DeWalt Extreme Masonry Drill Bit 5.5mm x 85mm

The DeWalt Extreme Masonry Drill Bit 5.5mm is crafted for powerful, efficient performance in demanding masonry applications. Built with a durable carbide head and high-temperature copper brazing, this drill bit is optimized for extended life and break-out safety. It’s designed to outlast standard DeWalt percussion drill bits, offering twice the lifespan and delivering up to 50% more holes per charge when used with a cordless drill. Ideal for professional and DIY projects, this bit combines durability with precise drilling action.

Featuring a hardened steel body with core reinforcement, this 5.5mm drill bit incorporates a large-volume, machined spiral that enhances drilling speed and tensile strength. The anti-slip shank, designed with three milled flat sides, secures the bit firmly in place within the chuck, reducing slippage and ensuring consistent, steady drilling. Additionally, the optimized carbide tip reduces “walking” and wandering, allowing for greater accuracy when starting holes.

Engineered for high performance across a range of masonry materials, this bit is suitable for drilling in brick, stone, tile, and light concrete, making it versatile for anchor installation, plastic plugs, fixings, and clearance holes for pipework. The milled flute design promotes fast dust and debris removal, keeping the bit cooler and increasing drilling speed, which is particularly advantageous when working in tougher materials.
