STAINLESS STEEL

The UFS technical brochure is dedicated to families of stainless steel taps, specifically developed for high-performance threading taps for stainless steel applications in demanding industrial environments.

A practical resource that brings together the most efficient machine taps for stainless steel machining, engineered to ensure process stability, consistent thread quality and extended tool life. The range includes both cutting taps and roll form taps, available for through holes and blind holes, with dedicated geometries such as spiral point taps, spiral flute taps 48°, and versions with coolant through taps solutions for improved heat dissipation and chip control.

Cutting taps are available in DIN 371 and DIN 376 executions, covering a wide range of thread standards including ISO 228 (G) and UNC/UNF taps, making them suitable for rigid tapping tools and CNC applications.

The solutions are manufactured in high-quality materials such as PM3, and are available with advanced coatings including TXC coated taps, VS and AHI, developed to increase wear resistance and optimize tool performance in stainless steel machining.

The range is offered in the LINE series, providing an excellent balance between quality and cost-effectiveness, and in the TOP series, featuring advanced surface treatments and PVD coatings for maximum durability and productivity.

By scanning the QR codes included in the technical tables for each product code, users can directly access the UFS online B2B portal to check stock availability, consult detailed technical data and identify technically alternative or complementary industrial threading solutions.

A resource designed for professionals seeking speed, precision and reliable technical support in stainless steel tapping, backed by the full expertise of UFS in industrial threading solutions.

45° spiral taps for blind holes. The special anti-bird’s nest spiral geometry ensures efficient chip evacuation, making them suitable for threading blind holes with depths up to 3xD. Recommended for stainless steel grades 2.1 and 2.2, as well as for mild steels, magnetic steels, and construction steels in groups 1.1 and 1.2.

Straight flutes with spiral point taps for through holes and thread depths up to 3xD. They are designed exclusively for through-hole applications. The chip flow follows the tool feed direction. Suitable for stainless steels, including the more demanding grade 2.4, they stand out thanks to the high-performance TXC coating and the distinctive blue ring.

48° spiral taps for blind holes. Suitable for deep blind-hole applications thanks to their excellent chip evacuation capacity. Available with or without internal coolant. Designed for stainless steels grades 2.1, 2.2, and 2.3, they are distinguished by the high-performance TXC coating and the characteristic blue ring.

Spiral point taps for through holes, PM3 sintered steel. A tool family designed for applications on stainless steels and thread depths up to 3xD. Suitable exclusively for through holes, the chip flow follows the tool feed direction. Recommended for stainless steels, including the more demanding grade 2.4, it stands out thanks to the high-performance TXC coating and the distinctive blue ring.

48° spiral taps for blind holes, PM3 sintered steel, horizontal taper IT (INOX Tapered), TXC coating. The high-helix design ensures particularly effective chip evacuation. Characterized by high productivity, they are suitable for applications on stainless steels, including the more demanding grade 2.4. The chips are evacuated in the opposite direction to the tool feed, while the horizontal taper prevents chip entanglement during the tap’s return stroke, reducing the risk of chipping on the rear threads.

Roll taps with coolant grooves for blind and through holes, tolerances 6HX, 2BX, ISO22X. Based on the principle of plastic deformation, they do not produce chips and create highly durable threads. Recommended for steel, stainless steel, aluminium alloys with Si content <10%, and copper. Generally suitable for medium-strength materials, with an elongation coefficient above 10% and a tensile strength Rm <850 N/mm². The required torque is 1.5–2 times higher compared to cutting taps. The coolant grooves facilitate lubricant flow, ensuring improved lubrication and heat dissipation.

Like the previous P2CC but with 6GX tolerance, therefore for applications where subsequent galvanizing treatment is expected, or similar, which require a higher tolerance than 6HX.

Roll taps with coolant grooves for blind and through holes, tolerance 6HX.  Based on the principle of plastic deformation, they do not produce chips and generate highly durable threads. Recommended for steel, stainless steel, aluminum alloys with Si content < 10%, and copper. Generally suitable for medium-strength materials with an elongation coefficient above 10% and tensile strength Rm < 850 N/mm². The required torque is 1.5–2 times higher compared to cutting taps.  The coolant grooves facilitate lubricant flow, ensuring improved lubrication and heat dissipation. Available with next-generation AHI coating and also in left-hand thread (LH) versions.
