Precautions for Operation
Summary of Issues Regarding Drill Bit Tip Breakage During Use
1. When drilling, ensure the hole saw and wood panel are securely fastened before proceeding.
Answer: If the wood panel is not firmly secured, vibration during drilling can cause the drill bit tip to break off.
2. Ensure the drill bit is locked in place before starting the drilling operation.
Answer: Failure to lock the drill bit securely causes loosening during drilling, leading to tip breakage.
3. Ensure the drill operates in forward rotation; never drill in reverse.
Answer: Reverse rotation prevents drilling, causes wood to emit black smoke, and burns the drill bit.
4. Do not drill with the bit tip pressed against the wood.
Answer: This can cause excessive torque, breaking the drill bit.
5. After the drill bit tip contacts the wood in the hole jig, lift it slightly upward before starting the drill. Once the drill speed stabilizes, apply steady downward pressure to drill.
6. Do not forcefully press down on the drill during operation; maintain a steady downward pressure.
Answer: Excessive downward pressure overloads the drill bit, causing excessive torque that may snap the bit.
7. After adjusting the angle drill jig's height, ensure the drill bit does not contact the jig's metal base plate. Secure the drill bit depth stop ring firmly in place.
Answer: Contacting the metal base plate may snap the drill bit.
8. Use a high-power hand drill; do not use low-speed, high-torque hand drills.
Answer: Excessive torque from the hand drill can easily break the drill bit.
9. Use hardwood-specific drill bits for hardwood; they are faster and more stable.
10. The drill bit is designed as a woodworking bit and is not suitable for drilling metal.
Answer: Drilling metal with this bit can easily break the drill bit.
