IRWIN Speedhammer Quad Drill Bit 12.0 x 460mm IW2039425

This IRWIN® Speedhammer Quad Drill Bit features a 12mm diameter and 460mm overall length, providing exceptional reach for the deepest drilling applications. This extra-long bit is essential for drilling through very thick walls, deep foundations, or when access requires extended reach whilst maintaining the popular 12mm diameter. The 4-cutter geometry drills a more concentric hole for the best fixing retention, whilst the full head carbide tip offers the highest levels of drilling life and durability. A unique bonding system connects the solid carbide head to the 4-flute spiral, providing faster, more efficient dust removal. The specially engineered grooves are designed to minimise friction, resulting in increased speed and longer life. Manufactured in Germany with premium steel, this drill bit meets PGM standards for drill bits used for anchor fixing, ensuring reliable performance on professional applications.
