2. MATERIAL: A thick diamond coating on the top offers superior cutting strength for maximum drilling outcomes.
3. PRACTICAL USE: Each diamond hole saw has a smooth finish that lower the incision resistance and drill pressure. The diamond hole saw makes clean and precise holes. The large clearance hole along the diamond hole saw facilitate the entrance of cooling water and escape of chips and particles from drilling.
4. IDEAL FOR: Tiles Glass Marble Granite
5. WE RECOMMEND: Always using lubrication (e.g., water) when in use. The diamond hole saw works best with an electric drill.
