Walter 7924241 Carbide Milling Insert Lnhu WSP45G

Product Description

The WALTER 7924241 is a double-sided carbide milling insert in the LNHU style, designed for high-performance face and shoulder milling operations on steel, stainless steel, and super alloys. Carrying manufacturer grade WSP45G with a PVD-applied TiAlN/Al2O3/ZrN multilayer coating, this insert delivers wear resistance and thermal stability in demanding cutting environments. It features four usable cutting edges, a right-hand cutting direction, and a corner radius of 0.80 mm (0.0315 inches). The L55T chip breaker geometry promotes efficient chip control across a range of feed and depth conditions. Licensed HVAC, plumbing, and similar trade technicians do not install this part; it is specified and installed by machinists and tooling professionals in metalworking operations.

The WALTER 7924241 is suited for milling applications on workpieces classified under ISO material groups P (steel), M (stainless steel), and S (super alloys). It fits LNHU-series milling cutter bodies that accept size 160708 inserts with a 5.5 mm screw hole diameter. The insert is screw-held and intended for right-hand cutting setups. Maximum depth of cut reaches 16.00 mm (0.6299 inches), making it appropriate for moderate to aggressive material removal passes in both roughing and semi-finishing contexts on CNC machining centers and manual mills.

Key Features

• Double-sided insert with 4 cutting edges for extended tool life and lower cost per edge
• PVD TiAlN/Al2O3/ZrN multilayer coating for heat resistance and flank wear protection
• L55T chip breaker geometry for controlled chip formation on steel and stainless steel
• Maximum depth of cut of 16.00 mm (0.6299 inches) supports medium to heavy milling passes
• Corner radius of 0.80 mm (0.0315 inches) reduces edge chipping and improves surface finish
• Screw-held mounting with 5.5 mm hole diameter for positive, repeatable seating in compatible cutter bodies

Compatibility

Designed for use in LNHU-series milling cutter bodies accepting insert size 160708. ISO catalog reference is LNHU160708R-L55T WSP45G. Compatible with workpiece materials in ISO groups P, M, and S: carbon and alloy steels, stainless steels, and super alloys.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Power down and lock out the machine spindle before seating or indexing inserts. Use the appropriate torx or hex key to tighten the clamping screw to the cutter body manufacturer's specified torque; do not over-torque, as this can crack the carbide substrate. Inspect the insert pocket and seating surface for chips or debris before mounting to ensure full, even contact.
