Diamond hole saw for grinder 20mm

Key Technical Specifications

• Diameter Size: 20mm (Perfect sizing for installing standard water supply lines, anchor bolts, conduit lines, and bathroom bathroom fittings).

• Thread Connection: M14 Internal Thread. This thread profile screws directly onto the spindle of standard 4.5-inch (115mm) and 5-inch (125mm) angle grinders without requiring chuck keys or separate arbor adapters.

• Manufacturing Technology: Vacuum Brazed Diamond Grit. This process fuses the industrial diamond crystals directly to the steel matrix at high temperatures, offering vastly superior cutting speeds and a significantly longer tool life compared to traditional electroplated bits.

• Maximum Operating Speed: Rated for speeds up to 11,000 to 14,000 RPM, perfectly matching the native operating velocity of commercial angle grinders.

• Cooling System: Most premium 20mm variants feature an internal cooling wax core inside the barrel. As drilling begins and temperatures rise, the wax melts to automatically lubricate and cool the diamond edge, allowing for effective dry drilling.

• Working Depth: Typically handles material thicknesses up to 30mm to 40mm.
