About this product
The IRWIN Speedhammer Plus is an SDS drill bit designed for fast drilling into brick, block, masonry, concrete and granite. At 20mm diameter and 460mm overall length (400mm working length), it suits deep drilling on specialist heavy-duty installations. A single flute design gives 28% greater capacity for efficient dust removal, reducing the risk of clogging, while also lowering vibration. The extra-short drill head takes on most of the workload for added durability and speed, and the bit contains 25% more tungsten carbide for extra strength. More aggressive, self-centring cutting angles help the bit start accurately and drill around 25% faster than comparable bits, while maintaining durability.
