10 head shapes:
Cylindrical and pointed cylinder, spherical, egg mold, bullet, point type, oval, post-shape, taper, reverse cone, so you can choose the shape according to your application.
There are some precautions for using, so you should be careful when processing and polishing.
1. For the best performance of the carbide drill, it is necessary to adjust the rotation speed for the cutting object.
2. The harder the material is, the lower the rotational speed.
3. Use with a higher rotational speed as small carbide drill.
4. When using, please constantly move and apply light pressure.
5. Using the rotation speed below the optimal rotation, it will lead to blade chipping.
6. Using worn tools or collets will lead to blade failure.
7. Do not submerge the carbide drill over 1/3 of the tip length.
8. The speed of rotation is too fast to wear the blade faster.
