Irwin Joran SDS-plus concrete drill bit with 4 cutting edges. The drill has a diameter of 5.0 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 life of the drill bit. 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 Prüfgemeinschaft Mauerbohrer eV (PGM®). The benefits of PGM®-marked drill bits include:

• Tight tolerance limits for diameter and symmetry of the carbide tip ensure the accuracy of the drill hole.
• Secure anchoring and fastening.
• Continuous quality assurance.
• Safety and trust in the product.

Compliance with these criteria is continuously monitored by PGM®, making the drill bits safe and reliable.
