The Irwin 5 Piece Glass and Tile Drill Bit Set is a specialist drilling accessory designed for precise work in glass, porcelain and ceramic materials. This versatile set provides tradespeople and installers with five essential sizes for a comprehensive range of drilling applications in delicate substrates where standard drill bits would cause cracking or damage. Each drill bit in this collection features a spear-point carbide tip specifically engineered for glass and tile work. The set includes 4mm, 5mm, 6mm, 8mm and 10mm diameter bits, covering the most commonly required hole sizes for bathroom and kitchen installations, splashback fitting, and glazing work. This size range makes the set ideal for tasks such as drilling pilot holes for fixings in tiled surfaces, creating openings for pipework through ceramic tiles, and installing fittings in glass shower screens. For optimal performance and to prevent material fracture, these bits should be operated at low speeds, with 300 RPM recommended by the manufacturer. Water cooling during drilling is also advised to reduce heat build-up and extend bit life. It is essential to ensure the hammer function is disabled when using these bits, as percussion drilling will damage both the bit and the workpiece.
