How to prepare for drill grinding
I. Preparation Steps Before Drill Grinding
- First confirm the drill diameter, then select the collet Ⓒ diameter.
- Insert the selected collet into the collet clamping nut Ⓑ at an appropriate angle.
- Insert the drill bit into the collet, extending it by about 35mm, but do not tighten it yet.
- Place the collet ring Ⓐ onto the collet Ⓒ and thread it into the collet clamping nut Ⓑ. Then screw it in lightly while ensuring the drill bit can still be rotated by hand.
- The above steps complete the preparation before drill grinding Ⓓ.
II. Steps for Replacing the Diamond Wheel
- Loosen and remove the screw (B1) on the machine, and open the wheel cover (B2).
- Use a 4mm hexagon wrench to loosen the screw (B3) counterclockwise.
- Replace with a new diamond wheel and tighten the screw back up.
- Close the wheel cover (B2) and securely tighten the screw (B1).
Caution! Do not turn on the power before the diamond wheel screw (B3) is tightened, the wheel cover (B2) is closed, and the screw (B1) is tightened, to avoid any danger.
