About this product
This 4.0mm HSS jobber drill bit from Faithfull is a general-purpose size suited to pilot holes for larger screws, dowel work and everyday drilling in wood or metal. It's a versatile diameter for woodworking, furniture assembly and light engineering tasks, offering a good balance of size and precision.
Made from high-speed steel to the DIN 338 standard, it has a straight shank for secure grip in hand or power drill chucks. It can be used on wood and metal, though a cutting lubricant is recommended when drilling metal to reduce friction and prolong bit life.
Overall length is 75mm with a 42mm working length, and the bit is supplied in a pack of 10.
