Thread forming (over thread cutting) eliminates costly and time-consuming chip clean-up and disposal. Improved tap life, even in abrasive materials...no cutting edges to get dull. Lubrication grooves allow forced passage of air and lubricant when tapping.

Fluteless taps are used for the forming of internal threads without chip removal. In contrast to conventional tapping where material is cut from the workpiece, thread forming is a pressure deformation process without chip removal for the production of internal threads.

Fluteless Taps (Forming Taps) are threading tools to form internal threads without cutting. The thread is produced by deformation of the material without damaging the fibre structure.

For tapping depths, more than twice the tap diameter, roll taps with oil grooves are recommended. These grooves provide a passage for the lubricant and also for the escape of air and oil to avoid a piston effect in blind holes.

These taps are designed for machine tapping in ductile materials. Also known as Cold Forming Tap, Roll Forming Tap or Fluteless Tap. Emkay Tools Hi-Performance Thread Forming Taps have no flutes or cutting edges but have special roll forming lobes with circular lands and short taper leads for through or blind holes.
