Rolled Flute Taps

Dormer Series E500 HSS Metric Thread Straight Flute Taps

A range of machine metric straight flute HSS taps from Dormer. The tap bit tolerance class is 6H and features a 2-thread input and a 7 degree cutting angle. These tap bits are recommended for use in both through or blind holes with a depth of up to 2 times 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.
