TNMG molded turning inserts are M‑tolerance triangular indexable carbide inserts designed for swiss type CNC lathe operations. Unlike fully‑ground inserts, these inserts are formed by molding and sintering process, delivering cost‑effective performance for general‑purpose turning jobs.
We supply a full lineup of coating grades to handle different workpiece materials including carbon steel, alloy steel, stainless steel, aluminum, high‑temperature alloy and titanium alloy. Optimized chip‑breaker geometry helps smooth chip evacuation, reduces built‑up edge and minimizes workpiece deformation during continuous turning. Standard stock sizes are available and custom solutions can be arranged for special machining requirements.

Q1: What is a TNMG 60° molded turning insert?
A1: It is a triangular 60° indexable carbide insert made by molding and sintering, designed for general turning on CNC lathes and swiss lathes.
Q2: What materials can TNMG molded inserts machine?
A2: They can machine carbon steel, alloy steel, stainless steel, cast iron, aluminum alloy, copper alloy, titanium alloy and some heat-resistant alloys.
Q3: How do I select the correct coating grade?
A3: Select the coating according to the workpiece material, hardness, cutting speed and feed rate. We can recommend the most suitable grade for your application.
Q4: Are TNMG 60° molded inserts standard?
A4: Yes, they follow the TNMG standard system and can be used with standard tool holders after confirming the size, hole diameter, thickness and corner radius.
Q5: Can I order custom TNMG inserts?
A5: Yes, we can produce custom TNMG molded inserts based on drawings, including special chipbreakers, corner radius, coating and material grades.
