Standard DIAMOND™ Hole Saws
1. If drilling in hard tiles and stones, pre-drill pilot hole using a ¼” One-Piece DIAMOND™
Hole Saw. Otherwise, assemble the arbor with a Carbide Tipped Pilot Bit. (Use a
2. Ensure that the work piece is supported to avoid flexing of the work piece during cutting.
This will help prevent cracking or breaking of the material.
3. Verify you are using the correct speed the size being used. Longest life is obtained by
using the correct RPM.
4. If possible, wet the work piece with water in the location you plan to cut. Water will
extend the life of the tool. If drilling without water, stop regularly to keep the saw from
5. Orbit the back of the drill in a small circular fashion while applying LIGHT PRESSURE
(15-20 lbs of force; See Figure 1 Above).
6. DO NOT use excessive force for cutting. This will strip the diamond grit from the edge
greatly reducing the life of the saw.
7. Remove each slug before the next hole is drilled.
NOTE: When using a drill press, an interrupted or “pecking” drilling method is recommended
to extend the life of the tool. Engage the hole saw and begin drilling and then stop every 5-10
seconds briefly and then re-engage the hole saw in the material. Repeat until the hole is
