How to use

Fit the hole saw to a suitable arbor and secure it to a drill that supports masonry cutting accessories. Mark the center point of the required opening, position the pilot bit (if present) and start drilling at low speed to establish the cut. Apply steady pressure and moderate, consistent feed without forcing the tool. Use intermittent operation or water cooling as appropriate for the material and manufacturer guidelines to limit heat buildup and remove dust. After cutting, withdraw the tool and clear debris from the hole to verify fit.

Usage recommendations

Wear appropriate personal protective equipment—safety glasses, dust mask and hearing protection—when cutting stone or concrete. Use a drill with sufficient torque and choose drill speeds suitable for masonry to prolong tool life. For deeper or larger cuts consider step cuts and periodic cooling to reduce wear.
