HSS Fluteless Taps
Fluteless taps are also referred to as "Roll Form" or "Thread Flow" taps.
Unlike standard taps, fluteless taps create internal threads by pressure deformation, rather than by material removal.
As a result, no chips are formed as no material is removed.
BA (British Association)
In 1884 the British Association for the Advancement of Science adopted a thread form and series, primarily for use in precision equipment.
It was inspired by one used in the Swiss watch and clock industry, and was formerly sometimes called the Swiss Small Screw Thread System; but is now just referred to as the BA series.
Like the Whitworth thread, it has a rounded root and crest, but the included angle is 47.5°.
Despite the date of origin and the British sponsorship, the BA is a metric series.
Not only is it based on the metre, but the thread frequency is specified in terms of round numbers in the pitch sequence, with threads per metre allowed to fall where it may.
Manufactured from HSS this fluteless tap is designed for use in medium tensile materials and is for hand or general machine use.
