Irwin Glass and Tile Drill Bit

The Irwin Glass and Tile Drill Bit in 10mm diameter is the largest size in the range, designed for substantial installations and heavy-duty fixings in glass, porcelain and ceramic surfaces. This diameter is ideal for major mounting projects including heated towel rails, large bathroom cabinets, substantial shelving units and other fixtures requiring maximum anchoring strength in tiled or glass areas. Built for precision drilling through demanding materials, this 10mm bit delivers optimal performance at low speeds of approximately 300 RPM with water cooling to prevent heat damage and material cracking. The substantial diameter provides excellent clearance for heavy-duty fixing systems whilst maintaining the clean, professional finish essential for high-quality installations.
