Why this Milwaukee Diamond Max hole saw stands out

• Diamond grit cutting edge designed for hard materials, delivering smoother entry and cleaner hole edges with less chipping than traditional carbide options.
• 1/2" hole diameter enables standard-sized penetrations for plumbing, wiring, and fixture installations in glass, porcelain, tile, and stone surfaces.
• 3" overall length provides ample reach for tile and countertop work without compromising control or stability.
• Arbor included and Quick-Change system for fast, hassle-free bit changes—minimizing downtime on the job site.
• 1/4" shank fits a broad spectrum of standard drill chucks, making it a versatile addition to professional and DIY tool kits.

Ideal use cases

• Installing electrical outlets, plumbing rough-ins, or venting through glass or ceramic tile backsplashes.
• Creating clean openings for glass panels, shower surrounds, or tile countertops where precision matters.
• Drilling through natural stone or porcelain tile for fixtures, insets, or hardware mounting.

Practical guidance for best results

• Secure the workpiece firmly and mark the drilling point to start with a precise pilot hole or guide mark.
• Use slow, steady feed pressure to maintain control and reduce chipping at the entry cut.
• Allow the bit to do the work; avoid forcing the cutter through the material to minimize edge breakout.
• After use, clean the cutter and store it in a dry place to preserve the diamond grit’s effectiveness.
