1-5/8 in. Diamond Hole Saws for Granite & Stone

Turbo Rim hole saws feature a segmented, wave-like edge that increases cutting speed and reduces heat buildup, ideal for faster material removal. Straight Rim hole saws provide a continuous cutting edge that produces smoother, cleaner cuts with less chipping — preferred when finish quality is a priority in granite, marble, or porcelain applications.

Yes, water cooling is strongly recommended when cutting granite and dense stone with a diamond hole saw. Water prevents overheating of the diamond segments, extends tool life significantly, and reduces dust. You can use a water feed attachment, a rubber dam filled with water, or continuously apply water manually during the cut.

For a 1-5/8 in. diamond hole saw on granite or stone, a lower RPM between 600–900 RPM is generally recommended. Higher speeds generate excess heat that can damage diamond segments. Using steady, moderate pressure with consistent water cooling ensures optimal cutting performance and maximizes the lifespan of your hole saw.

Yes, DI Tool's diamond hole saws are compatible with standard drills featuring a 5/8 in.-18 UNF threaded arbor connection. For best results on granite and stone, use a variable-speed drill that allows you to control RPM. A drill press or angle grinder with appropriate attachments can also be used for more controlled cuts.

The lifespan of a diamond hole saw depends on material hardness, cutting technique, and whether water cooling is used. With proper water cooling and correct drill speed, a quality diamond hole saw can cut dozens of holes in granite. Dry cutting or excessive speed significantly reduces diamond segment life and may cause premature wear.

Yes, the 1-5/8 in. diameter is a common size used for plumbing supply line holes, faucet cutouts in tiled surfaces, and electrical conduit openings through stone countertops or tiled walls. It is widely specified in bathroom and kitchen renovation projects where precise hole sizing is required through granite, marble, or porcelain tile.
