    Recommendations for use:

    Observe the recommended rotational speed.  Clamp the pilot drill in the hole saw arbor and make sure that it projects at least 1 8” over the teeth of the hole saw.  When cutting metals, use a high-quality cutting oil, if possible. This facilitates smooth running and lengthens the hole saw service life.  Exception: When working on aluminum, use kerosene instead of cutting oil.  Bi-metal hole saws are suitable for work on stainless steel (INOX).  In order to avoid corrosion, remove any particles which develop during work from the workpiece.  Clean the workpiece chemically or mechanically (etching polishing, etc.).  Make sure that all the teeth are applied evenly. To prevent tooth breakage, avoid swinging movements during sawing.  Avoid overheating the saw.
