Mitsubishi Materials | Small-Part Machining & Precision Grooving
The Mitsubishi MLG1015L UTI20T is a specialized precision insert designed for grooving and threading in small-part machining. Engineered for use with the SMG holder series, the MLG insert provides a stable, high-accuracy cutting edge. The UTI20T grade is a legendary uncoated tungsten carbide that offers superior edge sharpness and thermal conductivity, making it the premier choice for non-ferrous metals, aluminum, and cast iron.

| Grade / Composition | UTI20T (Uncoated Tungsten Carbide) |
UTI20T Uncoated Carbide
The UTI20T grade is an uncoated K-type carbide. Its micro-structure is optimized for anti-adhesion properties, which is essential when machining "sticky" materials like aluminum or copper. By eliminating the coating, the edge remains extremely sharp, reducing cutting pressure and preventing the smearing of material on the workpiece surface.
Precision Grooving Geometry
The MLG series is dedicated to precision grooving. This geometry ensures high chip control even at low feed rates. Its slim profile allows for access in tight spaces, making it a favorite for automatic lathe machining and medical or electronic component manufacturing.
Recommended Cutting Parameters
| Workpiece Material | Cutting Speed ($v_c$) | Feed Rate ($f$) |
|---|---|---|
| Aluminum Alloy / Copper | 100 - 300 m/min | 0.02 - 0.10 mm/rev |
| Cast Iron (FC/FCD) | 60 - 120 m/min | 0.03 - 0.12 mm/rev |
SMG HOLDER COMPATIBILITY
This MLG insert is designed for Mitsubishi SMG series external grooving holders.
