Irwin Glass and Tile Drill Bit

The Irwin Glass and Tile Drill Bit in 5mm diameter offers versatility for a wide range of glass, porcelain and ceramic drilling applications. This popular mid-range size is ideal for standard bathroom fittings, towel rails, robe hooks and similar fixings that require a balance between strength and minimal material intrusion. Designed for precision drilling without cracking or chipping, this 5mm bit delivers optimal results when operated at low speeds of approximately 300 RPM. Water cooling is recommended during use to prevent heat build-up and maintain cutting performance. The 5mm diameter provides sufficient clearance for most standard wall plugs and fixings whilst minimising the visual impact on tiled or glass surfaces.
