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

Dormer ’Shark Line’ Blue Spiral Point Taps for stainless steel. These taps are constructed from premium grade High Speed Cobalt (HSS-E) for increased hardness and improved edge strength with a tap bit tolerance class of 6H.

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.

Precision HSS taps designed to produce repeatable tolerance threads in most engineering materials. Suitable for medium/high rate production.
