The UFS Premium line represents the highest expression of our technology in the production of high-performance taps.
It is designed to ensure precision, durability, and production consistency in the most demanding applications, where tight tolerances, difficult materials, and challenging working conditions require superior tools.

The Premium range is the result of UFS experience in the automotive, precision engineering, mould and die, energy, and component manufacturing sectors, integrating latest-generation sintered materials, advanced coatings, and optimised geometries.

Distinctive features of the Premium line

High-performance materials

  • PM3 – high-strength sintered steel for demanding applications
  • PM1 – sintered material for multi-flute geometries and tight tolerances
  • HSSE – high-speed cobalt steel for universal precision applications

Advanced coatings

  • TiAlN – high thermal and wear resistance
  • TXC – multilayer coating for maximum durability
  • AHI – ideal for abrasive materials and critical applications
  • TiN – universal solution for steels and light alloys
  • V – vaporisation to reduce friction and improve stability

Special tolerances

The Premium line includes taps with standard and special tolerances:

  • 6H – ISO standard
  • 6G + 0.03 – for freer fits
  • 6H + 0.1 – for applications with subsequent coatings or treatments
  • 7G – for special assembly requirements

Premium families

The Premium line includes a selection of taps optimised for different materials, depths, and working conditions.
The main families are:

  • K26 – taps for cast iron, straight flutes, PM3, TiAlN coating
  • K27 – taps for cast iron and steels, FOR/FORY versions, PM3
  • E24 – spiral point taps for through holes, HSSE
  • E25 – DIN 376 spiral point taps, HSSE
  • E60 – 40° spiral flute taps for blind holes, HSSE
  • E61 – DIN 376 40° spiral flute taps, HSSE
  • E70 – taps for light alloys, TXC coating

Each family is available in different versions: standard, coated, with special tolerances, and with FOR or FORY internal lubrication.

Recommended applications

Premium taps are designed to deliver high performance in the following materials:

  • Steels up to 850–1200 N/mm²
  • Cast iron, grey and spheroidal
  • Aluminium alloys (including high-silicon alloys)
  • Copper alloys and brass
  • Austenitic stainless steels

They are particularly suitable for:

  • automotive components
  • precision engineering
  • moulds, dies, and tooling
  • machine tools
  • high-volume production applications

Advantages of the Premium line

  • Longer tool life thanks to PM sintered materials
  • Stability and production consistency even under demanding conditions
  • Reduced cycle times and scrap rates
  • Superior and repeatable thread quality
  • Availability of special tolerances for specific requirements
  • Versions with internal lubrication for deep applications

Customisations and special solutions

On request, UFS can manufacture customised Premium taps:

  • special lengths
  • dedicated geometries
  • special profiles (MJ, UNJC, UNJF, AVIO)
  • material-specific coatings
  • non-standard tolerances

Each solution is developed in collaboration with our customers’ technical departments and through testing carried out by our Technology Department.
