Irwin Joran SDS-plus concrete drill bit with 4 cutting edges. The drill has a diameter of 5.5 mm, is 160 mm long, and has a working length of 100 mm. The Speedhammer Quad SDS-plus concrete drill bit is Irwin's strongest concrete drill. The unique carbide tip is optimized for fast, continuous drilling even through reinforced concrete. SDS-plus drill bits fit into a rotary hammer or combination hammer with an SDS-plus chuck. SDS-plus drill bits have a 10 mm shank with two slots, preventing slipping in the chuck. The unique carbide tip extends the drill's lifespan. The 4 cutting blades reduce vibrations, prevent jamming, and ensure that dust and debris are removed evenly and efficiently. High-quality steel and manufacturing in Germany provide improved core strength for maximum durability and longer lifespan. The Irwin Speedhammer Quad drill bits are certified by the Mauerbohrer Testing Association (PGM®). The advantages of PGM®-certified drill bits include: tight tolerances for diameter and symmetry of the carbide tip ensure the accuracy of the drill hole, secure anchoring and fastening, constant quality assurance, as well as safety and trust in the product. Compliance with these criteria is continuously monitored by PGM®, making the drill bits safe and reliable.
