Irwin 4 Piece Diamond Tipped Drill Bit Set

The Irwin 4 Piece Diamond Tipped Drill Bit Set is a professional-grade drilling solution designed for fast, smooth cutting in all grades of hard and soft tiles. This versatile set includes four commonly used bit sizes, making it ideal for tilers, bathroom fitters and general contractors working with ceramic, porcelain and natural stone materials.

Each drill bit features a raised diamond grit edge that enables easy starting on hard tile surfaces without requiring a guide or pilot hole. The tough brazed diamond construction ensures fast cutting performance and extended tool life, even when working with challenging materials.

The innovative reverse spiral design forces water towards the cutting head, keeping the diamonds cool during operation to increase cutting speed and prolong bit lifespan. An auto slug ejection slot allows for continuous, uninterrupted cutting without the need to stop and clear debris. For optimal performance and maximum longevity, drilling with water is recommended to further cool the cutting surface.
