Why this hole saw is the right choice for your project
When you're shaping bathrooms, kitchens, or custom glass installations, accuracy matters as much as speed. The Milwaukee Diamond Max hole saw is engineered to minimize breakout and chipping on polished surfaces while delivering round, true holes. Its diamond grit edge cuts through hard tile and stone that standard steel hole saws struggle with, reducing the risk of misaligned cuts or rough edges that require cleanup.
Ideal use scenarios
- Installing faucet, shower, or tub fixtures through porcelain or ceramic tile without fracturing surrounding material.
- Creating clean openings for glass panels, shower doors, or decorative tile features in granite countertops or stone backsplashes.
- Routing electrical boxes, plumbing access, or hardware installations in stone or glass tile installations where a precise diameter is essential.
- Renovation projects in kitchens and bathrooms where durable, long-lasting tooling reduces downtime and waste.
Practical tips for optimal results
To get the most from your Milwaukee Diamond Max hole saw, follow these best practices:
- Mark the center clearly and start with a light, controlled plunge to establish a guided cut.
- Keep the workpiece well-supported and use a drill with a slow-to-moderate speed setting to prevent overheating and edge chipping.
- Maintain a steady feed rate—pause if the tool seems to bind, then resume with even pressure.
- Lubricate or cool with water during cutting to extend edge life and reduce heat buildup on hard materials.
- Expect a two-step approach on very hard or thick tile: a shallow first groove, then a deeper pass to complete the cut while keeping the surface intact.
- Pair with a compatible arbor and secure clamping to avoid wobble during operation.
