Product Details
Descriptions about Angle Grinder
- high efficiency : brushless motor has no friction between brush and electric coil, low energy loss and higher efficiency. 12
- long life : Since there is no friction, the motor has a longer life, and there is no need to replace the carbon brush, reducing maintenance costs.
- high safety : brushless motor will not produce sparks, to avoid the risk of fire caused by sparks.
- low noise : The noise of brushless drill is lower, and the use experience is better. 2
- strong performance : brushless electric drill will not have a strong instant impact when starting, and it is more comfortable to use.
lower price : The cost of brushed electric drills is relatively low, suitable for users with limited budgets. 3
mature technology : Brush motor technology is mature, repair and replacement parts are easier to find.
Application scenario
High efficiency requirements : If you need an efficient, long life and safe tool, the brushless drill is the better choice.
on a limited budget : If you are on a limited budget, a brushed power drill is an affordable option.
Lithium electric drill is a kind of electric drill tool that uses lithium battery as a power source.
Next, explain the concept and characteristics of lithium electric drill in detail:
I. Basic definition
Lithium electric drill is a kind of power tool, which uses the electric energy provided by the lithium battery to drive the rotation of the drill, so as to drill holes, tighten screws and other operations. Because of its convenience and high efficiency, lithium electric drill is widely used in home decoration, engineering construction, machining and other fields.
Second, the characteristics of lithium batteries
The reason why lithium electric drills are favored has a lot to do with the lithium batteries they use. Lithium battery has the advantages of high energy density, long life and no memory effect. This means that it can store more electrical energy in a smaller volume, providing continuous and stable power for the drill. At the same time, the lithium battery has many charging times, long service life, and will not cause battery capacity attenuation due to partial charging.
Three, the function of electric drill
Lithium electric drill can not only carry out drilling operations, but also adjust the speed and torque to adapt to different work needs. Modern lithium electric drill is also equipped with many intelligent functions, such as overload protection, battery power indicator, etc., to make the operation more convenient and safe.
Application and advantages
Lithium electric drill because of its lightweight, easy to operate characteristics, especially suitable for home decoration of wood, metal, plastic and other materials drilling. Compared with traditional electric drills, lithium electric drills are lighter and reduce fatigue during operation. At the same time, the long life of lithium batteries also reduces the maintenance cost of users.
In summary, lithium electric drill is a lithium battery-powered power tool, with high efficiency, convenient, easy to operate and other characteristics, widely used in various fields. Because the lithium battery it uses has many advantages, the lithium electric drill has become one of the indispensable tools in modern industry and home decoration.

Safty Instruction
A recoil is a sudden reaction to a squeezed or stuck spinning wheel, back pad, brush, or any other accessory. Squeezing or hooking causes a rapid stall of the rotating attachment, which in turn causes the uncontrolled power tool to be forced in the opposite direction to the rotation of the attachment at the restraint point. For the previous ample, if the grinding wheel is snagged or pinched by the workpiece, the edge of the grinding wheel entering the pinch point may penetrate deep into the surface of the material, causing the grinding wheel to crawl out or kick out. The wheel can jump towards or away from the operator, depending on the direction the wheel is moving at the squeeze point. Under these conditions, the grinding wheel may also break. Kickbacks are the result of misuse of power tools and/or incorrect operating procedures or conditions and can be avoided by taking the appropriate precautions given below.
a) Firmly hold the power tool and adjust the position of the body and arms to resist the recoil force. Always use an auxiliary handle (if provided) to maximize recoil or torque reaction during start-up. If proper precautions are taken, the operator can control the torque reaction force or recoil force.
b) Do not put your hands near rotating accessories. Accessories may bounce off your hand.
c) If recoil occurs, do not place your body in an area where the power tool will move. The recoil will push the tool in the opposite direction to the wheel movement at the hook point.
d) Be especially careful when handling corners, sharp edges, etc. Avoid bouncing and snagging attachments. Corners, sharp edges, or bounces can easily snag rotating accessories and cause loss of control or recoil.
e) Do not install chainsaw woodcarving blades or serrated saw blades. This blade can cause frequent recoil and loss of control.
