Stainless taps of the V82 and V83 series, with helical grooves and strong torsion, are specifically designed and built to tap blind holes with a depth up to 3.5 x D in stainless steels, offering high reliability as industrial tapping solutions.
In the UFS R&D department, extensive testing was carried out using various tool types and configurations – starting with super-high-speed steel (HSS) materials for the taps and progressively integrating other metals to develop higher-performance alloys. The goal was to ensure high productivity, extended tool life and reliable tapping of medium-to-high strength steels, including carbon steels, alloy steels and precision machining tools for stainless steels (work-hardening, austenitic and ferritic).
The optimal solution was determined to be high-speed steel tools HSSV3 (high-speed steel with 3% vanadium), combined with a specialized geometry: a steep 48° helix, which facilitates smooth machining, effective chip control, and a drastic reduction in built-up edge formation.
Additionally, the tools feature a TXC coating that prevents adhesive wear and promotes chip evacuation, offering excellent resistance to wear and heat. This multi-layer coating comprises a soft, self-lubricating outer layer with a low friction coefficient, underlaid by a very hard, high-durability base layer.
The synergy between geometry and coating makes the UFS V82 and V83 tap series ideal for machining tough materials prone to adhesion. Unlike generic-purpose taps – which often cause chip clogging or ‘bird’s nests’, leading to production stops – these stainless steel taps produce consistent, well-formed chips, significantly reducing interruptions in the manufacturing process.
The blue color ring easily identifies their specific application range, making them a reliable choice among helical groove taps.
