Irwin Glass and Tile Drill Bit

The Irwin Glass and Tile Drill Bit in 7mm diameter provides increased capacity for larger fixings and more substantial installations in glass, porcelain and ceramic surfaces. This size is particularly useful for heavier bathroom accessories, grab rails, substantial shelving brackets and installations requiring greater load-bearing capacity. Designed for precision and control, this 7mm bit delivers excellent results when operated at low speeds of approximately 300 RPM with water cooling to protect both the bit and the material being drilled. The larger diameter makes it suitable for heavy-duty wall plugs and fixings whilst still maintaining the clean, crack-free holes essential when working with brittle materials.
