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 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. Clear away wood chips or iron filings frequently to prevent the hole saw
   from overheating.
5. Always apply the necessary pressure for the intended use. Too much
   pressure can destroy the teeth when cutting in metals.
6. 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.
