About this product

A 20mm x 400mm masonry drill bit for drilling into hard building materials including brick, concrete, stone and block. Made from heat treated steel, it gives the extra length needed for deeper holes and jobs where a standard brick bit does not reach far enough.

Used for building work, renovation, installation and general site or home maintenance, this long masonry bit suits anyone drilling through solid walls and dense surfaces. It is a practical option for fitting pipework, cable runs, brackets, fixings and other fittings where extra drilling depth is needed in brickwork or concrete. Suitable for trade use and DIY repairs alike, it helps when working on garages, outbuildings, extensions and similar masonry tasks.

The 400mm length is useful when access is awkward or when drilling through thicker material, while the 20mm diameter suits larger fixing and clearance holes where required. Heat treated steel construction gives this 20mm drill bit a strong, durable build for repeated drilling work in tough surfaces. Supplied as a single long masonry bit, it is a straightforward choice for keeping the right size close to hand when larger diameter holes come up. For regular drilling in brick, block and concrete, the longer reach also helps reduce the need to stop and change approach on deeper jobs.
