About this product
An SDS drill bit designed for fast drilling into brick, block, masonry, concrete and granite. It has a diameter of 4.0mm, a total length of 160mm and a working length of 100mm, giving extended reach for deeper holes or thicker masonry sections.
The bit uses a unique single flute design offering 28% greater capacity, helping clear dust efficiently and reducing the risk of clogging while lowering vibration. An extra-short head takes 80% of the workload, improving durability, and the bit contains 25% more tungsten carbide for added strength. Aggressive, self-centring cutting angles help the bit drill faster while maintaining durability.
