Rolled Flute Taps

Dormer E200 Straight Flute Metric Machine Tap Bits

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.

Bright finish fluteless taps; for use on copper, aluminium, magnesium, brass, zinc etc.
Flash chrome finish fluteless taps; for use on steel up to 850N/mm² tensile strength, free matching and austenitic stainless steel
Made to ISO529 standard for tapping blind and through holes in a wide range of ductile materials
Smooth non-cutting action produces greater thread formed strength, higher life expectancy and increased tapping speeds especially where excessive tension occurs
