Forming Taps

Forming Taps otherwise known as ‘Roll’, ‘Fluteless’ or Polygon taps. Used for the chipless production of threads in ductile materials such as copper, aluminium, soft brass or steel. Threads produced by fluteless taps are formed by plastic deformation, they are not cut.

These taps do not have flute or cutting edges but have special roll forming lobes with circular land. They are operated at high speeds and are better at maintaining gauge qualification.

Because they produce no chips they are very suitable for blind hole application as well as through hole application.

• Can be used in both blind holes & also in through holes
• Chips are pushed upwards due to spiral flute – Chip clogging avoided
• Full thread depth can be achieved and this design prevents tap breakage
