Recommendations for use:
- Clamp the pilot drill in the hole saw arbor and make sure that it projects at least 3 mm (1/8") over the teeth of the hole saw.
- When cutting metals, use a high-quality cutt ing oil, if possible. This facilitates smooth running and lengthens the hole saw life. Exceptions: When working on aluminium, use kerosene instead of cutting oil.
- HSS hole saws are suitable for work on stainless steel (INOX). Remove any particles which develop during use from the
workpiece in order to avoid corrosion. Clean the workpiece chemically or mechanically (etching/polishing, etc.).
- Make sure that all the teeth are applied evenly. Avoid swinging movements during sawing to prevent tooth breakage.
- Avoid overheating.

Safety notes:
When using shank extensions, the recommended
hole saw rotational speed must not
be exceeded.
