LNGU Shoulder Milling Inserts for Precision Face & Shoulder Milling

The LNGU series of shoulder-milling inserts is designed for demanding face and shoulder milling operations in industrial manufacturing setups. Featuring negative geometry, robust substrate and advanced coatings, these inserts deliver superior stability, excellent surface finish and consistent tool life on steel and stainless steel materials. 

Grades Offered & Material Coverage

• Grade PA1025 – optimised for steel finishing under continuous cut conditions.

• Grade PA1825 – designed for heavier steel milling and semi-interrupted cutting.

• Grade MA1525 – tuned for stainless steel applications, offering excellent built-up-edge resistance and surface finish.

Why Buyers Choose LNGU Series

• Longer tool life and predictable wear reduce downtime and cost per part.

• Compatible with standard shoulder mill cutter bodies using LNGU style inserts, enabling easy retrofit and stock consolidation.

• Enhanced chip control and edge geometry reduce surface defects and improve repeatability in production.

• Suited for automotive, mold & die, machine tool and general industrial manufacturing environments.

Typical Applications
Face milling and shoulder milling of steel and stainless steel components where precision, surface finish and throughput matter; semi-finishing and finishing operations; high-volume production where tooling stability translates into lower cost per part.
