Irwin Speedhammer SDS Plus Masonry Drill Bit

This IRWIN® Speedhammer Quad Drill Bit features a 5.5mm diameter and 160mm overall length, offering a specialist size for specific fixing requirements. The 5.5mm diameter is ideal for applications requiring a slightly larger hole than standard 5mm fixings, providing versatility for precision masonry and concrete drilling tasks. 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.
