Product information

The thread milling cutter line (catalog L73–L82) includes ISO metric full profile solid carbide thread mills, American UN full profile thread mills, BSP(G)-55° full profile thread mills, NPT-60° thread mills and partial profile 60° thread mills, with tolerance classes 6g/6H for metric and standard NPT per USAS B2.1:1968. The supplier's solutions deck groups thread mills into single-tooth (1T), three-tooth (3T) and full-tooth (KM) styles and states that thread milling offers process flexibility (one tool covers a diameter range, left- and right-hand threads), reliable machining in difficult materials such as titanium alloy and stainless steel, and suitability for high-hardness materials above HRC 60 and large-diameter threads.

Product details

One thread mill can cover a range of diameters and both left- and right-hand threads through CNC program adjustment, reducing the variety of dedicated tools in stock.

Thread milling is presented by the supplier as suitable for difficult-to-machine materials such as titanium alloy and stainless steel and for blind holes, avoiding tap breakage risk.

The supplier states the process can handle high-hardness materials (HRC>60) and large-diameter threads.

Thread mill styles

Solutions deck slide 22 · 3 entries

The catalog groups thread mills by how many teeth engage the thread.

Style codeCharacteristicAdvantage
1TUniversal, covers a very wide working rangeOne cutter handles several thread diameters and pitches, so far fewer sizes have to be stocked — especially useful for non-standard and sampling work. Cuts both right-hand and left-hand threads.
3TCost-effective, with good accuracy and early finishing in one passCombines roughing and finishing in one tool, which extends tool life. Thread taper is reduced, so thread accuracy is easier to hold.
KMHigh efficiency, good surface finishFastest cycle per part: fewer passes, less machining time, high efficiency and good surface finish.

Variable pitch thread mills (A60° / G55°)
