HOLE SAW CARBIDE GRIT 20MM - RED

Using a hole saw:

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

• A portable 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 pin-type mandrels for hole saws larger than Ø32mm. When mounting the mandrel, lift the pins up and then screw the mandrel down into the hole saw as far as it will go. It is important that the pins holes are securely located in the hole saw.
3. Use the correct rotation speed. If the speed is too high or too low will have an effect on the cutting edge on the hole saw and decrease the life expectancy.
4. Always apply the necessary pressure for the intended use.
5. Keep the drill going straight to avoid binding the hole saw.
