CMT Diamond Dry Hole Saw - 3/4" x 1-9/16" x 2-3/8" by CMT is engineered for precision dry cutting through hard tiles, natural stones, and artificial stones using an angle grinder. With a 3/4" cutting diameter and a 5/8"-11UNC threaded shank, this diamond hole saw delivers clean, accurate holes in ceramic, granite, marble, and engineered stone surfaces - making it a practical choice for tile installers, countertop fabricators, and stone workers who need reliable performance without water cooling.

Key Features

• Diamond dry hole saw design for angle grinder use - attaches directly to a standard angle grinder via a 5/8"-11UNC threaded shank, so you can use the tool you already own without any adapter hardware.
• Filled with cooling wax - the built-in wax melts during operation to manage heat at the cutting edge, protecting both the blade and the workpiece during dry cutting so you get longer blade life without water.
• 3/4" cutting diameter with 1-9/16" cutting height - sized for precise, clean-through holes in tiles and slabs of standard installation thickness, reducing the chance of chipping or overcut on finished surfaces.
• Up to 14,000 RPM rated speed - built to handle the high rotational speeds of an angle grinder, giving you consistent cutting performance across hard and dense stone materials.
• Right-hand rotation (RH) - matches the standard rotation direction of angle grinders, ensuring safe, predictable engagement with the material from the first contact.
• Suitable for hard tiles, stones, and artificial stones - one saw covers a wide range of demanding materials including ceramic, gres, granite, marble, and engineered surfaces like Silestone or Okite, reducing the need for multiple specialty bits.
• 2-3/8" total length - compact enough to maintain good control during handheld angle grinder work while still providing adequate reach through thick tile or stone.

Why This Product

• Dry cutting capability combined with integrated cooling wax means you can drill through granite, marble, and hard ceramic tile without setting up water cooling equipment - reducing job site complexity and cleanup time.
• The 5/8"-11UNC shank is a standard thread found on most angle grinders, so this diamond hole saw can be put to work immediately without sourcing a separate adapter or specialty tool.
• A 14,000 RPM speed rating gives this saw the headroom to run safely at typical angle grinder operating speeds, protecting both the operator and the tool from the risks of running an underpowered or over-stressed blade.
• With a cutting height of 1-9/16" and compatibility across hard tiles, natural stone, and artificial stone materials, this single saw handles the range of materials commonly encountered in countertop and tile installation work.
