Drill and tap holes in a single pass with this combined drill-tap bits set
Tuesday 20 September 2022
New in the Laser Tools range is this set of six combined drill-tap bits designed to drill and tap a hole in a single pass (part number 8405). Each bit has been manufactured from high speed steel (HSS4241) and coated with a super-hard, ceramic titanium-nitride coating for edge-retention and corrosion resistance.
The 1/4" hex drive drill-tap bits feature a drill section at the forward end of each bit that forms the perfect-sized tap hole in the material. The following tap section then cuts the threads. The bits include spiral flutes to clear the swarf created plus a deburring shoulder to ensure the edge of the hole is finished without any sharp edges. Bits included: M3 x 0.5; M4 x 0.7; M5 x 0.8; M6 x 1.0; M8 x 1.25 and M10 x 1.5mm. Suitable for drilling and tapping iron or carbon steel plate up to 3mm thick and aluminium or copper plate up to 6mm thick.
A 60mm long magnetic bit holder is also included that features a quick-chuck end for ease of use. Supplied in a useful storage case, the set is available now from your Laser Tools stockist.
