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.
Specifications

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 code | Characteristic | Advantage |
|---|---|---|
| 1T | Universal, covers a very wide working range | One 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. |
| 3T | Cost-effective, with good accuracy and early finishing in one pass | Combines roughing and finishing in one tool, which extends tool life. Thread taper is reduced, so thread accuracy is easier to hold. |
| KM | High efficiency, good surface finish | Fastest cycle per part: fewer passes, less machining time, high efficiency and good surface finish. |
