A rotary hammer drill or a rock drill (jackhammer) is ideal as they provide both rotation and percussive action. For very hard rocks like granite, a Down-The-Hole (DTH) hammer drill is highly effective.
3.Gather Safety Gear:
Wear safety glasses to protect your eyes from flying debris.
Use work gloves for a firm grip and hand protection.
Consider hearing protection due to the noise generated.
4.Mark the Spot:
Clearly mark the desired location for the hole on the granite surface using a marker or tape.
5.Prepare for Cooling:
Have a water source nearby for cooling the bit and suppressing dust, especially for deeper holes.
Starting the Hole
1.Position the Bit:
Place the tip of the drill bit on your marked spot.
2.Begin Drilling:
Start drilling at a slow speed with light, consistent pressure. Engage the hammer function from the beginning to help break down the rock. Avoid pushing too hard to prevent damaging the bit or overloading the drill motor.
3.Maintain Pressure:
As the bit begins to penetrate the granite, maintain a steady grip and continue applying consistent pressure.
Drilling and Progress
1.Continue Drilling:
Once the hole is initiated, continue drilling at a moderate speed with consistent, firm pressure.
2.Clear Debris:
Periodically withdraw the drill bit slightly to allow dust and debris to escape the hole. Use water for cooling and dust suppression.
3.Inspect the Bit:
Check the bit tip for any signs of damage or excessive wear. Allow the bit to cool if necessary.
Finishing the Hole
1.Withdraw the Bit:
Slowly withdraw the bit while it's still rotating to clear any remaining debris.
