Dormer Threading Tap, M4 Thread, Metric Standard, Machine Tap

A range of machine metric thread spiral flute HSS-XS1 taps from Dormer with a tap bit tolerance class of 6H. Specially formulated high helix of 45º allows adequate room for chip formation and rapid and smooth chip evacuation at high cutting speeds for threading blind holes of up to 2.5 x diameter of the tap used. The 3 radii flute profile gives a constant rake angle all along the flute length, while the short thread length means low torque and better chip evacuation.

Threading taps are used to create threads for bolts in materials like metals and plastics. Threading taps work like a drill but due to the unique shape of a tap, when they are screwed into a piece of material, screw threads are created. Taps can be used in machines like drill presses or with hand tools such as a tap wrench.
