Types of Hammers and Their Uses (Part 2)

 The Hammer Club

The design of Club Hammer is one of the most effective and satisfying designs for our work. It has double-sided print heads, making it versatile enough to successfully perform various types of work.

For example, we can use it to drive steel chisels and masonry nails. Although you can use it for domestic work, the hammer is also suitable for light disassembly work.

Therefore, we should not give up their power. It allows debris to fly over the whole place, which is why it is recommended to use appropriate equipment to avoid accidents.

6. The hammer

This is where things start to get serious. The hammer is ideal for tasks requiring power and high intensity.

Sledgehammers are an ideal solution for dealing with surfaces that do not slip using any other type of tool. An obvious example of its ability is its ease of breaking through concrete, masonry, or different types of stone.

That is not the only purpose, though. If we swing the hammer like an ax, we can use it for heavy work to cope with all the damage we need. However, we can still use it for lighter work by just using the weight of the head.

Like the last one, sledgehammers require us to wear safety gear. Not only does it get into our eyes, but it also prevents us from being harmed by unexpected influences.

Joinery Hammer

7. The Joiner's Mallet

Joinery Hammer is the first hammer in this list with wood features for the head and handle and is designed to provide high-quality performance through different structural designs.

Professionals usually use this hammer to drive a chisel or to strike a wooden joint. It is designed to perform certain software tasks, while metal hammers can cause confusion.

08. Soft-faced Hammer

These hammers provide an alternative when steel hammers are not careful, and carpenter hammers are not an option. Soft hammers can handle materials that do not require high pressure to form or break on them.

09. Power hammer

The best choice for nails and staples.

These hammers allow us to operate automatically, thus taking care of our convenient work. Over the long days, we had to hammer in each nail one by one, and that's the main reason why these hammers are so successful.

We found that they come in two sizes, one for light and one for heavy. The first model lets us take care of the frame and shape of the frame. Heavy electric hammers, on the other hand, are better suited for floors and denser operations.

If you want to work faster without a lot of effort and effort, these hammers are the tools you need. Rotary and drill hammers are the most popular power hammers.

The last word

The various hammers are available on the market offer many possibilities for our work. However, we must keep their specifications in mind to understand what they can or cannot do. We are a Hammers Manufacturer China. If you are interested in our products, please contact us at any time.

Types of Hammers and Their Uses (Part 1)

 One of the most common tools we use in most projects throughout our lives is a hammer. It's a tool that allows us to work with materials, destroy them often, reshape them later, and create something better and more beautiful.

Choosing the right choice can be tricky because there are so many options available. In this article, Hammers Exporter China introduces the most popular types of Hammers you can find.

Different kinds of professional hammers

01. Claw hammer

The most popular hammer to get through is the Claw Hammers. If you've ever worked as a handyman around your house, you've probably used it.

It is easy to find in most garages because of its perfect balance between comfort and weight and its powerful ability to generate an impact on most surfaces and produce high-quality results.

For their design, manufacturers usually use wood, fiberglass, and sometimes steel handles. It comes with or without a rubber handle, but we recommend that you purchase a handle with a rubber handle for added comfort. Its total weight is between 455-680 grams.

The claws usually have a curved design and are combined with a V-shaped shape, ideal for pulling nails out of wood. We can use this claw to lever the floor and other surfaces that need to be levered.

However, in all cases, we must always be careful, as excessive force may weaken the joints of the handle and its head.

Claw Hammers

02. Roundhead hammer

The hammer has a circular design and one of its main purposes is to help us shape the metal and close the rivets. Therefore, the hammer performs well in professional applications, and its design makes it versatile enough to be used in different types of applications.

For example, we can mention that engineers are the target audience for using it.

In most cases, the handle is wood. It comes in different weights and shapes. It is an effective tool for both professional and domestic use.

03.Straight Pein

Another metal hammer. Of course, you can use it for different applications and it will perform very well, but the cross pin is very effective for the pins and tacks in the boot panel. For handles, it features wood.

04.Cross Pein Pin Hammer

This hammer attempts to improve the comfort of the previous hammer while also reducing weight and providing a comfortable design. It weighs about 55 grams (or 4 ounces). It performs well and produces high-quality results, especially in cabinetwork and light carpentry.

 

Essential Knowledge of Circular Saw Blades (Part 3)

 ■Dado saw blade

Table saws (and some rocker saws) can use the combined stacked dado kit.

For cutting 7/8" wide single-lane wall panels (skirts), grooves and notches, depending on the machine. These kits include two external cutting blades (one with left helical teeth and the other facing right Oblique teeth) and internal saw blades (with flat top teeth). Stack any combination of internal saw blades between the external saw blades to obtain the required passing width.

■Aperture

The size of the hole in the center of each circular saw blade matches the saw shaft (saw blade driveshaft). Most blades with a diameter of 10 inches or smaller are mounted on a 5/8-inch saw shaft, but 12-inch blades use a 1-inch saw shaft. If the saw shaft and the inner hole of the saw blade do not match, you need to use a reducing ring to reduce the diameter. This is due to the different table saw shaft standards in Europe and the United States. North America often uses inch shaft diameters, and the EU often uses metric systems. Shaft diameter size, and because of the difference in the standards they define for table saws, there will be different shaft sizes such as 15.875mm, 25mm, 30mm, etc. In China, because sliding table saws, circular saws, etc. often adopt European standards, our market The saw blades that are purchased are usually 25mm and 30mm shaft holes.

■Saw Blade Coating

Some saw blades have so-called coatings on the substrate, such as titanium plating, nitride black, chromium nitride color, etc., such coatings are designed to reduce friction, rust, and resin accumulation. Of course, some special saw blades are coated with metal or PTFE to resist the deformation of the saw blade substrate, maintain the hardness of the saw blade, and prevent heat generation. This kind of coating can effectively protect the saw blade and eliminate sawdust in time. The high-quality coating keeps the saw blade sharp for longer and consumes less energy. There are two different types of coatings that can be used for saw blades, one for the saw blade substrate and the other for the saw teeth. When the saw blade has two types of coatings, they will be different coatings because they achieve different purposes.

The saw blade substrate is coated with a protective layer to prevent rust or friction. Modern metal processing has developed a variety of manufacturing methods and used different alloys in the casting process to improve durability. The type of coating depends on the hardness of the metal making the saw blade, the rake angle, the back angle (clearance angle), tooth shape design, bonding material, and general-purpose. Some manufacturers paint saw blade substrates, mostly blue, red or orange, to provide brand recognition, but they can still provide rust-proof boards. Some high-cost saw blades are coated with polytetrafluoroethylene (PTFE) to reduce friction. This type of coating can be very valuable because the greatest friction comes from the debris clamped between the saw blade plate and the material being cut. By coating the saw blade substrate, these fragments will not stick to the saw blade. In addition, sometimes the material will squeeze the saw blade, even if the saw blade substrate is thinner than the teeth, especially for hand-held circular saws and electric saws.

The serrated coating is an important part of extending the life of the saw blade. Wood products are highly fibrous and tend to dull any saw blade. When cutting hard materials such as composite materials or plywood, the temperature is easily close to the melting point. This requires additional overheat protection. The harder the material used on the teeth, the longer the blade will last without dulling the teeth. Therefore, some extremely hard materials are used to cover the serrations.

Carbide serrations can also be improved by coating. Tungsten, titanium, cobalt, or vanadium can be electroplated on the cemented carbide to increase its surface hardness, reduce serration wear, and maintain sharpness for longer. The material can be identified by the color of the saw blade. In addition to permanent sharpness, this coating also has the characteristics of clean cutting, has a certain anti-corrosion performance, and will not damage the internal structure of the metal. The only disadvantage of carbide saw blades is that the coating is lost after re-sharpening.

Circular Saw Blade

■Expansion tank

In addition to the saw blade coating, in order to release the residual welding stress of the saw blade, eliminate the expansion of the saw blade body and reduce chattering, the lines and holes cut by the laser and the expansion grooves, vibration holes, etc., are well passed through the air. Convection measures to eliminate the heating of the saw blade, of course, also have the effect of reducing vibration and noise. Some saw blades are also filled with soft metal in the grooves and pores as a means of damping. These are the saw blade protection measures developed by saw blade manufacturers.

The expansion slot is a laser cutting slot, you can also call it an expansion joint, designed to disperse heat and prevent the saw blade from overheating and deforming. The sawing process will cause a lot of friction even under ideal conditions. When the teeth of the saw blade remove material, they are also rubbing the sides of the saw blade. The tooth tip rubs against the material on the cutting path. This friction can generate amazing heat, enough to scorch wood and even twist saw blades. The saw blade is quite hot even after cutting; when trying to remove the saw blade from the table saw, tap it with your hand and it will be easily burned. The best way to avoid burns is to cool down after shutdown. However, this does not solve the problem of overheating.

As the temperature of the metal increases, the metal shows a tendency to expand. The temperature of the saw blade is usually not uniform on the saw blade, forcing it to expand unevenly. Generally speaking, the saw blade substrate is hotter than the saw teeth, although the saw teeth are experiencing most of the friction. Even though the sawtooth has the greatest friction, it can be cooled by air movement. Therefore, when the saw blade substrate expands, it needs to be released. The outer edge of the saw blade substrate, where the saw teeth are attached, is not so hot, so there is no such big expansion. The saw blade substrate is deformed to the side, which is the cause of warpage. Saw blade warping becomes a waste product, so it is necessary to prevent them from expanding unevenly to avoid the risk of warping. One method is to use high-density alloys in the saw blade substrate. The other is to cut expansion grooves on the saw blade substrate by laser. Allow the saw blade to expand "inside". Although these cut grooves seem to be for artistic decoration, they can absorb the metal expansion and prevent warping of the saw blade.

Finally, to explain the knowledge of the saw blade thoroughly, we need to further explore the knowledge points of speed, noise, feed rate, tooth gap, sawing ability, substrate material, sawtooth shoulder, and so on. However, I think for beginner woodworking enthusiasts, the above ten points are enough to help you correctly understand the saw blade, choose the saw blade and use the saw blade.

Essential Knowledge of Circular Saw Blades (Part 2)

 ■Number of teeth

Except for grinding saws used for cutting ferrous metals, glass, and ceramic tiles, all circular saw blades have many teeth scattered on the circumference. The number of teeth on the saw blade is one of the most obvious characteristics of the intended use of the saw blade, and it is also one of the biggest issues to consider when choosing a saw blade. It is usually the first parameter that should be considered when buying a saw blade. This quantity will describe whether it is designed for longitudinal or transverse cutting, wood or masonry, thick or thin materials. There are two extreme types: saw blades with fewer but larger teeth, with larger spacing between each tooth, used for longitudinal cutting; and saw blades with many small teeth, used for cross-cutting.

Saw blades designed for slitting generally have fewer teeth. They are designed to take a larger piece of sawdust from the wood or "bite" it, cutting faster. Since slitting is easier than cross-cutting, having a saw blade that can cut larger chips can improve efficiency without sacrificing cutting quality. In order to adapt to this rapid cutting, according to the size and quality of the saw blade, the number of saw teeth of the longitudinal cutting saw blade will be less than 40, more than 18 teeth, and there are large tooth grooves between. On the other hand, when saw blades are used for cross-cutting, they need to cut the grain of the wood so that they are smaller bites and produce smaller chips.. This requires more serrations instead of large cogging. The cross-cut saw blade has 60 to 150 teeth. The more teeth the saw blade has, the smoother the cut. Hollow ground or plywood saw blades have roughly the same number of teeth, but please note that the performance of these saw blades is significantly different from what is considered a combination/multipurpose saw blade. Combination saw blades are between these two numbers, ranging from 40 to 80 teeth. These saw blades are a compromise solution designed to allow the same blade to be used for longitudinal and cross-cutting.

For most woodworkers, the number of teeth of the saw blade is the most important part when choosing a saw blade. Generally speaking, a higher number of teeth indicates a higher quality of the saw blade, because each tooth added to the saw blade increases the cost of the saw blade. This is especially true for carbide saw blades. However, just the number of sawteeth is not enough. The best way to find a saw blade that suits your needs is to cut 25.4mm thick wood at any height.

Circular Saw Blades

■Tooth

The tooth groove is the circular space in the saw blade base plate between the saw teeth. This space is designed to take away debris such as sawdust and wood chips. Prevent the saw blade from clogging. The size of the tooth groove on the saw blade is closely related to the feed speed factor. The cross-cut saw blade has more teeth, so the tooth groove is smaller, and the heavy-duty saw blade and the longitudinal saw blade have a larger tooth space between each tooth, which can quickly remove wood chips. The tooth groove must be used to prevent the saw blade from overheating and the material being cut from burning. If there is not a large enough gullet, the sawdust will be trapped, stick to the saw blade, and increase friction, thereby generating excess heat. Since wood chips burn more easily than solid wood, it is actually possible (though not common) to catch fire in this way. If there is enough overheating, the saw blade will begin to warp, which increases the thickness of the saw path and eventually damages the saw blade. Therefore, it is not recommended to try to use a cross-cut saw blade for longitudinal cutting. The tooth grooves on the cross-cutting saw blade are small, and the more frequent saw teeth are accompanied by smaller teeth, and the ability of the saw teeth is not enough to transport a large number of chips and wood chips. The cutting speed of the cross-cut saw blade is slow, and there is enough time to discharge the waste, so there is no need for large tooth grooves. But forcing the wood to pass through the saw blade can also block up due to the accumulation of sawdust and sawdust.

Combination saw blades can be used for longitudinal and transverse cutting. When used for slitting, the saw blade will accumulate too much sawdust in the saw gap. Some combined saw blades solve the problem of chip accumulation by skipping teeth and adding an extra deep tooth groove after every five teeth. The deep tooth grooves between the sawtooth profile groups can provide a place for excess sawdust to be removed from the saw grooves, thereby eliminating overheating problems.

Compared with hardwoods, softwoods tend to produce larger, looser piles of wood chips. Therefore, for cork, the problem of wood chips accumulating in the tooth grooves will be more serious. If you are cutting damp wood, the problem will increase because the dampness of the wood will cause the wood chips to clump together instead of falling off the teeth. As the saw blade becomes more and more clogged, the temperature will rise, which can only be noticed when the table saw begins to deform or the saw blade begins to bend. The reason for the opposite situation is the obvious error, which is less likely to occur: when the slitting saw blade is incorrectly used for cross-cutting, the serrations caused by the slitting saw blade are not neatly handled, a lot of waste, and a lot of waste and large Block of sawdust, which prevents people from using it. Although the grade of the saw blade is not determined by the size of its tooth groove, it is easy to see when inspecting the saw blade. Saw blade designers consider the intended use of the saw blade and ensure that they provide sufficient tooth spaces for the intended use. When the saw blade is used outside of its intended purpose, especially when the cross-cutting blade is used for slitting, the tooth space may be insufficient.
