Taps for threading aluminium, copper and iron

The UFS technical brochure is dedicated to the families of taps for threading Aluminium, Copper and Iron (AL-CU-FE), designed to ensure high performance in tapping light alloys, mild steels and copper alloys.

A practical tool that brings together the most high-performance solutions of threading taps for soft or medium-hard materials, where cutting speed, chip evacuation, thread cleanliness and tool life are essential. The range includes taps for aluminium, taps for copper and taps for iron, available for through holes and blind holes, with specific geometries such as spiral flute taps, straight flute taps and roll-form taps.

Solutions with AZ alternate threads and chamfers designed to improve lubrication, reduce friction and optimize threading quality even in long-chip materials are included.

The range includes cutting taps and roll-form taps (P-ROLL), available in the LINE series, reliable and cost-effective for standard industrial applications, and TOP, with surface treatments and PVD coatings for maximum performance and longer tool life.

Thanks to the QR codes shown in the technical tables, users can quickly access the UFS B2B portal to check availability, consult detailed technical data and identify alternative products.

A tool designed for those looking for precision, efficiency and innovation in tapping non-ferrous and ferrous metals, backed by UFS expertise in the threading tool sector.

Straight flute taps with interrupted thread, for tapping materials such as magnetic soft iron, copper, and light aluminium alloys. The interrupted thread (AZ) eliminates the risk of chips welding to the thread flanks and breaking; it also reduces friction and allows for better lubrication and more space for chip passage. For blind and through holes up to 1,5xD.

Spiral point taps for through holes and AZ interrupted threads, for specific applications on aluminium alloys with Si<0,5%, iron, and copper. For machining with thread depths up to 3xD. The AZ interrupted thread reduced the risk of chips welding to the thread flanks and breakage of the taps or thread itself. It also reduces friction and allows for better lubrication, leaving more space for chip passage.

Taps with 15° helical flutes for blind holes up to 1.5xD. The combination of the helix and the alternating thread (AZ) promotes chip breaking and prevents the "bird nesting" on materials such as magnetic soft iron, light aluminium alloys, and copper.

Spiral point taps for through holes, for applications on aluminium alloys with Si<0.5%, iron, and copper. Thread depths up to 3xD. Special geometry for machining long-chipping materials; reduced number of cuts and wider flutes for improved chip evacuation.

Spiral flutes taps 45° with a reduced number of flutes for blind holes up to 3xD deep. The wide flutes and high helix angle, ensure effective chip removal when threading materials such as light aluminium alloy, iron, and copper alloys.

Spiral point taps for through holes, thread depths up to 3xD. Suitable for light aluminium alloys with Si<0.5%, iron, and copper. Special geometry for machining long-chipping materials; reduced number of flutes and wider grooves for better chip evacuation.

Thread rolling taps without lubrication grooves, tolerances 6HX, for blind and through holes. Based on the principle of plastic deformation, they produce no chips and generate a very strong thread. Recommended low thickness sheet metal, soft materials with high deformation, and light aluminium and copper alloys. In general, these taps are suitable for materials with a tensile strength Rm < 850 N/mm² and a minimum elongation coefficient of 10%. The torque is 1.5–2 times higher than that of metal cutting taps.

Like the previous P2SC 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, 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.
