Diamond hole saw for grinder 40mm

Key Technical Specifications

• Diameter Profile: 40 mm (approx. 1-9/16 inches) — perfect for standard 1.5″ pipes.

• Spindle Interface: Standard M14 Female Thread. It screws directly onto the spindle of standard commercial 4.5-inch (115mm) and 5-inch (125mm) angle grinders. This rigid mechanical connection ensures zero vibration or chuck slippage under load.

• Abrasive Matrix: Vacuum Brazed Diamond Grit. Industrial diamond crystals are molecularly fused to the rim of a hardened carbon-steel alloy cylinder under high-temperature vacuum settings. This gives the bit an exceptionally sharp grinding face that outlasts traditional electroplated or carbide-tipped hole saws by up to 10 times.

• Speed Capability: Optimized for high-velocity dry micro-grinding between 10,000 and 14,000 RPM. The grinder’s high native speed shaves the material incrementally rather than hammering, ensuring chip-free edges.

• Dust & Heat Management: Built for seamless dry use. Features deep side ventilation slots that eject abrasive masonry dust instantly, dropping internal temperatures and making it simple to push out stuck core plugs.
