Laser 8405 7 piece Combination Drill & Tap Bit Set

A set of 6 combined drill tap bits designed to drill and tap a hole in a single pass. Each bit has been manufactured from high speed steel (HSS) with a titanium-nitride coating for hardness, rust resistance and longevity. The tap bits feature a drill section at the end of each bit which forms the perfect sized tap hole in the material for the following tap section to then cut the threads into, together with spiral flutes to clear the swarf created; plus a deburring shoulder to ensure the edge of the hole is finished without any sharp edges. The set also includes a 60mm long magnetic bit holder with a quick-chuck end for ease of use.
