MLG1015L UTI20T
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.

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.

Technical FAQ & Buying Guide
When choosing CNC cutting tools, check the full model code, dimensions, grade and selected variant before ordering. Do not rely on the product image alone.
For carbide inserts, tool holders, drills and end mills, compare the mounting dimensions, connection type and manufacturer's specifications with your holder or machine. If you are unsure, share your existing part number and machining application with us before ordering.
Check the product listing for the selling unit, pack quantity and included components. If it is unclear whether the price is per piece or per pack, or whether a tool body and inserts are sold separately, contact us before purchasing.
Select cutting speed, feed rate and depth of cut using the relevant manufacturer's recommendations for your tool model, workpiece material, machine conditions and coolant method. The same settings are not suitable for every product or application.
