Using a hole saw:

To use a hole saw, you need the following accessories:

• A portable drill or stationary drill with a 3 jaw chuck.
• The correct mandrel and pilot drill for the material being drilled into.
• The necessary safety equipment. Safety goggles, gloves and hearing protection.

IMPORTANT:
For the best results and for safety reasons, use the recommended rotation speed for the material being drilled into.

For longer hole saw life, use the following instructions:

1. Use the correct mandrel for the diameter hole saw being used.
2. Use the correct rotation speed. If the speed is too high or too low, it will have an effect on the cutting edge and decrease the life expectancy.
3. Always apply the necessary pressure for the intended use.
4. Keep the drill going straight to avoid binding the hole saw.

TIP:
When using a hole saw for wood, clamp an off-cut backing board on the back to prevent tear out when the hole saw exits the material. The backing board also prevents materials from flexing.
