General description The Irwin Diamond tipped drill bits are designed for fast and smooth cutting in all grades of hard and soft tiles. Their raised diamond grit edge allows for easy starting in hard tile without the need for a guide. The tough brazed diamond grit ensures fast cutting and long life, while the reverse spiral design forces water towards the cutting head, keeping the diamonds cool to enhance cutting speed and prolong the tool's lifespan. Drilling with water further increases the lifespan of the drill bit. The auto slug ejection slot enables continuous, uninterrupted cutting.
