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

A range of cobalt metric pitch machine tap bits that meet stringent high-production machining demands due to significant resistance to wear and high temperatures. These tap bits have a short entry of 2-3 threads and the tap bit tolerance class is 6H. The taps cutting angle is 10° and the tap flutes are straight. These taps also feature a reinforced shank and a shiny surface treatment.

These excellent quality tap bits are ideal for tapping in blind or through-holes to depths up to two times their diameter.

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.
