Hole Saw Use and Care Information
Lubricants – Use a good cutting oil for faster, more efficient cutting in ferrous metals. Do not use cutting oil when cutting cast iron. Paraffin or beeswax is frequently used when cutting aluminum.
Workpiece position – Do not enter the workpiece at an angle. It is important to have all the saw teeth in contact with the material to avoid tooth damage.
Feeds – Hole saws require a level, even pressure to saw efficiently. Excessive pressure will contribute to premature wear, dulling of the teeth and tooth breakage. When cutting thick material, the saw should be removed from the cut at intervals to allow for chip clearances.
