Hole saw, core drill bit, practical non-slip stone for concrete, glass, ceramic tiles (30mm)

Features: 1. First, position the drill at a 45-degree angle, then drill the hole vertically (note the low-speed operation of approximately 800-1000 RPM). 2. Suitable for bench drills, electric drills, and machine tools with a drilling function, but not for impact drills (the impact function cannot be used for drilling). 3. Suitable for drilling stone, ceramic, glazed tiles, glass, etc. You must continuously add water for cooling during the drilling process. 4. The drill bit's cutting edges adopt a cross-section design for reduced cutting resistance and are also conductive for chip removal. 5. The universal triangular drill shank effectively prevents slippage during drilling and can withstand higher torque. 6. The long oval hole on the drill bit is more conductive for chip removal.
