Irwin Joran SDS-max concrete drill bit with 2 fixed cutting surfaces and 2 individual cutting teeth. The drill bit has a diameter of 18.0 mm, is 340 mm long, and has a working length of 200 mm. The Irwin SDS-max concrete drill is optimized for fast and efficient drilling even through reinforced concrete. SDS-max drill bits fit into a rotary hammer or combination hammer with an SDS-max chuck. SDS-max drill bits feature an 18 mm shank with three slots, preventing slipping in the chuck.

The carbide tip is soldered for a strong and durable connection with the drill bit. The 4 cutting edges ensure that dust and debris are quickly removed. High-quality steel and manufacturing in Germany provide improved core strength for maximum durability and longer lifespan. The Irwin Speedhammer Max drill bits are certified by the Testing Association for Masonry Drills (PGM®). The advantages of PGM®-certified 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.
