Angle Grinder Diamond Core Bit
Fast, Clean Hole Cutting Directly with M10 Angle Grinders
Engineered for clean and precise hole opening on tiles, marble, and hard stone. A secure, direct-mount connection ensures steady cutting without the need for water cooling.
Durable Diamond-Grit Edge
A thickened steel body combined with a wear-resistant diamond coating provides stable cutting strength on hard stone surfaces. The heavy physical base supports high-load applications while actively helping to reduce chipping and damage along the edges.
Dual dust & chip clearance
Designed with prominent longitudinal side clearance slots and specialized V-shaped (arrow-pattern) cutouts along the bottom edge. This integrated structural layout evacuates grinding dust quickly, maintaining a cooler cut and preventing burn-out during dry operation.
Direct M10 Thread Mounting
Installs directly onto the threaded spindle of compatible M10 angle grinders without requiring additional adapters or chuck conversions. This close, tight physically threaded connection prevents slipping and minimizes vibration under high-speed rotations.

Frequently Asked Questions
💡 Does this hole opener require water to cool down during drilling?
No. This diamond-coated hole saw is specifically designed for dry operation. The built-in bottom V-shaped cutouts and long side slots quickly clear stone dust, which aids in heat dissipation during dry cutting.
💡 Can I use this hole opener with a standard hand electric drill?
Out of the box, this tool features an integrated M10 internal thread, designed specifically for direct mounting on M10 angle grinders. To use this with a standard hand electric drill, you must purchase a separate M10 shank adapter.
💡 How do I start drilling a clean hole without a center pilot bit?
Since this tool does not have a center pilot drill, start the cutting process by holding the angle grinder at a 45-degree angle to establish a crescent-shaped groove on the tile or marble. Once this groove is cut, slowly upright the tool and proceed with circular, rocking motions to finalize the hole.
