Milwaukee Diamond Max 1-3/8" Diamond Grit Hole Saw for Glass, Porcelain, Tile & Stone

Take the guesswork out of drilling clean, precise holes in hard materials. The Milwaukee Diamond Max hole saw combines rugged diamond grit engineering with a compact 1-3/8" diameter for fast, dependable cuts through glass, porcelain, tile, and stone. Its 2.9" overall length and 0.5" cutting depth give you just enough reach for standard installations without over-penetration.

Key features that matter in real-world work

• Diamond grit construction designed to slice through hard surfaces with reduced risk of chipping and cracking, ideal for porcelain tiles, granite slabs, glass panels, and natural stone.
• 1-3/8" diameter is a versatile size for common openings such as electrical boxes, plumbing passes, and decorative hardware in tile or stone installations.
• 2.9" overall length and 0.5" cutting depth provide controlled, shallow cuts that protect underlying substrates and deliver consistent results.
• Shank diameter 7/16" and Quick-Change system enable fast swap-outs with compatible drill settings, reducing downtime on working days.
• Arbor not included – requires a compatible arbor for your drill setup. Pair it with a suitable arbor to complete your tool kit.
• Style focuses on Glass, Porcelain, Tile, and Stone applications, making this an all-purpose accessory for bathroom remodels, kitchen backsplashes, and stone countertop work.

Who this is for

• Professionals and DIY enthusiasts tackling tile bathrooms, subway tile mosaics, or glass panels where clean edge results matter.
• Renovators working with porcelain and ceramic tiles who need a dedicated hole saw that minimizes cracking and chipping.
• Stone and granite installers needing precise, repeatable holes for mounting fixtures or routing cables without compromising material integrity.

Practical tips for best results

• Use a light, steady feed and let the diamond grit do the work—avoid heavy pressure that can cause wander or chipping.
• Cool the cut with water or a dedicated coolant to extend blade life and reduce heat-related damage.
• Ensure you have a compatible arbor for your drill; this hole saw ships without an arbor, so set up your drill accordingly before starting.
• Mark your drilling location clearly and start with a small pilot guide if needed to improve hole accuracy on slippery tile surfaces.

Whether you're installing new fixtures, routing through a glass window panel, or creating precise openings in stone countertops, the Milwaukee Diamond Max 1-3/8" Diamond Grit Hole Saw delivers durable performance, focused on reliability when it matters most. Add it to your toolkit for quick, accurate openings in hard materials.
