HOW TO USE:
- Select the Correct Bit: Choose the drill bit size (from 1mm to 13mm) that matches the diameter of the hole you need to create.
- Secure the Workpiece: Always clamp your material firmly to prevent it from moving during drilling. This ensures safety and accuracy.
- Insert Bit into Drill: Securely insert the drill bit into the chuck of your drill (corded or cordless), ensuring it is centered and tightened properly.
- Set Drill Speed: Adjust your drill’s speed according to the material you are drilling. Slower speeds are generally better for harder metals like stainless steel, while higher speeds can be used for softer materials.
- Start Drilling: Place the tip of the drill bit on the marked center of your desired hole. Apply steady, moderate pressure, allowing the 135-degree split point to initiate the hole without walking.
- Maintain Consistent Pressure: Keep a consistent, firm pressure as you drill through the material. Avoid excessive force, which can overheat the bit.
- Clear Chips (for deeper holes): For deeper holes, periodically withdraw the drill bit slightly to clear chips from the flutes. This prevents chip buildup and reduces heat.
- Cooling (Optional): When drilling hard metals, consider using a cutting fluid or coolant to prolong bit life and improve cutting performance.
- Finish Drilling: Continue until the desired depth is reached. Once the hole is complete, slowly withdraw the drill bit while the drill is still rotating.
