Irwin Speedhammer Plus Drill Bit 4.0 x 110mm IRW10501943

The IRWIN SDS Speedhammer Plus Drill Bit is engineered for high-performance drilling in tough materials such as brick, block, masonry, concrete, and granite. Its patented extra-short drill bit head takes on 80% of the workload, enhancing durability and speed while ensuring efficient waste removal. The design includes a patented single flute that clears dust directly into the flute, reducing clogging and contributing to lower vibrations for better control. The bit features 25% more tungsten carbide for extra strength and offers faster drilling compared with similar bits. In addition, the cutting angles are more aggressive and the tip is self-centering, supporting faster and more precise drilling in demanding applications.
