These taps are designed for tapping in ductile materials. Fluteless taps have no flutes or cutting edges, but have special roll forming lobes with circular lands.

The advantages of Fluteless tapping are:

Elimination of Tap Breakages: There are no chips to cause jamming or cutting edges to grow dull or break down.

The Fluteless Design: produces threads with unbroken metal grain fibres. The threads therefore are much stronger.

Better Control of Tapping Hole Sizes:   Fluteless taps cannot be forced into lead-error or go oversize when changes occur in machine or operators pressure. The clamping of the work piece is important as the method of forming threaded holes compared with conventional tapping creates additional torque of up to 50%.

Blind Hole Tapping:   No chips to cause interferece at the bottom of the hole. In plating operations there are not chips to cause rejects.

Longer Tap Life:   The fluteless tap is substantially stronger than a conventional tap; hence there is longer tool life.

Faster Tapping Speeds:  The fluteless tap will ultimately produce more tapped pieces per hour.
