2. Vibration
Like noise, a certain vibration of household power tools is inevitable, however, high-quality power tools will try to reduce the vibration phenomenon to improve the comfort and precision. In addition, low vibration and low noise are one of the characteristics of the high-quality household electric tools.
3. Convenience
Power Tools having compact size and highly integrated electric will will be more popular than large volume, single-function products. Recommend that everyone should carry out horizontal comparison in the purchase of household electric tools.

What Are Classification of Grinding Wheels?

Grinding wheel is the most important class of abrasives & grindings. Due to different abrasive, bond and manufacturing processes, grinding wheels characteristics are vary wide, so the grinding process quality, productivity and economy have an important impact. The characteristics of grinding wheel mainly determined by the abrasive particle size, hardness, structure, binder, shape and size and other factors.
According to abrasive material, grinding wheels can be divided into ordinary and natural abrasive grinding wheel, natural abrasive grinding wheel has diamond grinding wheel and others.

According to the shape can be divided into flat-shaped grinding wheel, bevel wheel, cylindrical grinding wheel, cup wheel, disc wheel and so on; In accordance with the binding agent can be divided into ceramic wheel, resin wheel, rubber wheel, metal grinding wheel. The main parameters of grinding wheel are abrasive, viscosity, hardness, binding agents, shape, size and so on.

What Characteristics Does Hammer Drill Have？

What are the characteristics of a good hammer drill? We sort out five characteristics hammer drill should have, as follows:
1. Damping system, it can not only make staff comfortable to hold, but also relieve fatigue. By "vibration control system" to achieve; soft handle increases comfort feeling to hold.
2. Speed switch, when touch the switch, speed is relatively low, the machine can help smooth tripping.
3. Stable and reliable safety clutch, during use, this is a way to avoid a large torque reaction force to the user due to catching drill arising, which is a safe protection for user.
4. Comprehensive motor protection devices, in use, it is inevitable to enter the machine for granular hard objects, if the motor does some protection, high-speed rotation can easily be touched off by a hard object or scraping wire, resulting in motor failure.
5. Reversing function, application scope of hammer drill is broader and broader, its manifestations mainly is achieved through switch or adjust the position brush. This benefit is easy to operate and effective to protect the commutator, it can also extend motor life.

Use Hand Tools Carefully

1. When use the hand tools, you must wear eye protection equipment.
2. Select the hand tool that is suitable for the job nature.
3. Choose contractors recommended tools.
4. Maintain hand tools good performance. First, avoid rust. Second, keep the handle secure safe. Finally, keep the hand tools section sharp.
5. Tools section has sharp edges, be careful for hand tools, when handheld hand tools, not to climb the ladder.
6. When nearby places may have flammable substances, explosive dust or gas, it should be used in spark-proof tool.
7. The work should not use worn or broken tools.
8. The high-altitude operations, measures should be taken to prevent the hand tool shedding from the hands, it may hurt workers working on the ground.
9. Ensure that the adjustable portion of tool has been greased to prevent wear and alignment errors.
10. If use the hand tools, it will generate extremely loud noises, you shall wear ear protection.

Distinction of Electric Drill, Impact Drill and Hammer Drill

Power tools belong to large wide range of electrical products, which are widely used in construction, machinery, electric power, petrochemical, metallurgy, transportation, agriculture and other industries. Power Tools products have entered the home, and now drills are diverse on the market, let's take a closer distinguish of different types of drill.
Electric drills can only drill, impact drills not only can drill, but also can have a little hammering effect. Hammer drill can drill and higher hammering.
Electric drill: it only rely on motor driven gear to increase strength of the drill bit, make the drill bit do the scraping ripped form on a metal, wood and other materials.
Impact drill: In operation, the drill chuck has the adjustment knob, it has adjustable drill and impact drill two ways. Impact drill is the use of the inner shaft gear beating to achieve impact, the impact is less than hammer. It can also reinforce concrete, but ineffective.
Hammer drill: It is the use of bottom motor to drive two sets of gear structure, one set achieves drill, and the other set is driven the piston, it has a strong impact, along with the drilling results. Forces can crack stone and gold.

Precautions of Angle Grinder

There are many uses of angle grinder, carpenters, bricklayers, welders are commonly used angle grinders.
Small angle grinder is often used power tools in our daily lives, Angle grinder is designed for grinding, sawing and cutting function is not the designer's mind. Because angle grinder has high speed, the use of the blade and cutting films can not be forced pressure, can not cut more than 20mm hard material, otherwise, once stuck, it will cause machine cutting, chip fragmentation splash, or the machine out of control, which will damage goods, more serious is hurt people! Please choose more than 40 high-tooth blade, and keep your hands to operate, do good protective measures.

Category of Garden Tools

According to using the occasion categories, garden tools include gardening tools and garden tools.
