1.Basically can be replaced by small shank grinding wheel, and no dust pollution.

2.High production efficiency. Processing efficiency than manual file is improved by ten times, than small shank grinding wheel increased nearly ten times.

3.Good processing quality, high degree of finish. Can produce various high precision shape of the mold cavity

4.Long service life. Durability than high speed steel tool increased ten times, over 200 times more than the small grinding wheel.

5.To master convenient, easy to use, safe and reliable.

6.Processing costs can be reduced by dozens of times.

1.Carbide rotary burrs on the pneumatic or electric tool use, speed is 6000-40000/ min, must clamp tool.

2.Cutting direction from right to left uniform movement, not like the use of wheels like a reciprocating cutting; pay attention not to overexert ( pressure is generally not more than4 kg.).

3.Work because the chip flying, please use the protective glasses
