Combination Drill & Tap Bit Set 7pc(-8405)
€39.36 | €32.00 excl. VAT
A set of 6 combined drill tap bits designed to allow for a hole to be drilled and threaded with 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 blank 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 magnetic bit holder with a quick-chuck end for ease of use. 6x tap drill bits with 1/4″ Hex drive: M3 x 0.5 (max 400rpm), M3 x 0.7 (max 400rpm), M5 x 0.8 (max 350rpm), M6 x 1.0 (max 300rpm), M8 x 1.25 (max 250rpm), M10 x 1.5mm (max 200rpm). Supplied with a magnetic bit holder. Length: 60mm. Suitable for drilling, tapping or cutting on thin iron or carbon steel plate up to 3mm thick & aluminium or copper plate up to 6mm thick.
