1 1/8 Inch Diamond Hole Saws for Tile & Stone

A turbo rim diamond hole saw features a serrated, wave-like edge that allows faster cutting speeds and better water and debris removal. A straight rim provides cleaner, smoother cuts with less chipping, making it preferable for delicate or polished tile surfaces where finish quality is the priority.

Yes, using water as a coolant is strongly recommended when drilling tile and stone with a diamond hole saw. Water prevents the diamond segments from overheating, extends the tool's lifespan, reduces dust, and helps maintain cutting efficiency. Dry cutting can prematurely wear down the diamond rim and risk cracking the tile.

For a 1 1/8 inch diamond hole saw on tile or stone, a lower RPM between 600–1,200 RPM is generally recommended. Starting slowly allows the diamond rim to establish a guide groove, reducing the risk of slipping. Using steady, moderate pressure combined with water cooling produces the cleanest and most accurate cuts.

Yes, a 1 1/8 inch diamond hole saw is suitable for porcelain tile. Porcelain is a dense, hard material, so a diamond-tipped hole saw is one of the few tools capable of cutting through it cleanly. Use water cooling, low RPM, and consistent pressure to achieve a clean hole without cracking the porcelain.

Most 1 1/8 inch diamond hole saws are compatible with standard drill arbors. DI Tool's diamond hole saws feature a universal shank design for easy attachment. Always verify the arbor thread size — common options include 5/8"-11" threads — to ensure compatibility with your drill or rotary tool before purchase.

The lifespan of a diamond hole saw depends on the material hardness, cutting technique, water usage, and RPM. On tile and porcelain, a quality diamond hole saw can last for dozens of holes when properly used with water cooling and correct speed. Dry cutting or excessive pressure will significantly shorten the tool's service life.
