About this product
A masonry drill bit in a 12mm x 400mm size, made for drilling into brick, concrete, stone and block. The extra length is useful when you need more reach than a standard bit can give, whether for deeper holes or access through thicker material.
Used for building work, renovation jobs, fixing tasks and general site or home maintenance, this 12mm drill bit suits anyone drilling into hard masonry surfaces. It is a practical option for fitting brackets, running fixings into walls, drilling through blockwork, or handling repair work where a longer bit helps reach the required depth. Suitable for trade use, workshop preparation and DIY repairs where solid materials need a proper masonry bit rather than a general-purpose drill bit.
Made from heat treated steel, it is built for regular drilling work in tough materials. The 12mm diameter suits jobs that call for a larger hole size, while the 400mm overall length gives added reach for thicker walls, deeper anchor points or awkward access areas. It is described as suitable for most drills, which makes it a useful choice when you need a straightforward replacement or spare bit for common masonry drilling jobs. For repeated maintenance or installation work, having the right length close to hand helps avoid stopping to change approach mid-job.
