Irwin Speedhammer Plus Drill Bit 4.5 x 160 mm

The IRWIN SDS Speedhammer Plus Drill Bit is designed for fast, efficient drilling into brick, block, masonry, concrete, and granite. Featuring a patented single flute design for quick dust removal and lower vibrations, it supports smoother operation. An extra-short head handles 80% of the workload, increasing durability and speed, while dust is cleared directly into the flute to reduce clogging. With 25% more tungsten carbide for strength and 28% greater capacity for faster waste removal, these bits drill 25% faster than comparable drill bits and employ more aggressive cutting angles with self-centering for quicker, precise results.
