HSS hole saw

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 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:

Use the correct rotation speed. If the speed is too high or too low, it will have an effect on the cutting edge on the hole saw and decrease the life expectancy.
Clear away metal filings frequently to prevent the hole saw from overheating.
Always apply the necessary pressure for the intended use. Too much pressure can destroy the teeth when cutting in metals.
Keep the drill going straight to avoid binding the hole saw.
