Kennametal 6084948 KCPM40 Milling Insert Solid Carbide Lnpu

Product Description

The KENNAMETAL 6084948 is a solid carbide milling insert in the LNPU series, designed for high-performance face and shoulder milling of steel, stainless steel, superalloys, and titanium. It carries a dual PVD coating of TiAlN and AlCrN for heat resistance and extended tool life at elevated cutting speeds. The insert measures 25.00 mm (0.9850 inches) wide and 10.00 mm (0.3940 inches) thick, with a length of 29.00 mm (1.1420 inches). Four cutting edges and a chamfered and honed edge style help control chip formation and reduce entry shock. The HD chip breaker geometry supports aggressive cuts in difficult workpiece materials. Licensed machinists and CNC tooling technicians install this insert in compatible milling cutter bodies.

This insert is intended for use in MEGA45 series cutter bodies. Its left-hand configuration, positive rake geometry, and rectangular LNPU insert shape make it suited for shoulder milling operations on ferrous and exotic alloys in both production and job-shop environments. The insert style code is LNPU863 per ANSI and LNPU2410 per ISO standards, with a 90-degree included angle and a corner radius of 3/64 inch (0.0469 inches). It is held in the cutter body with a screw-lock mounting method.

Key Features

• Dual PVD coating — TiAlN and AlCrN — for thermal stability and wear resistance in steel and superalloy cuts
• Four usable cutting edges on a single-sided rectangular insert for extended tool life per unit cost
• HD chip breaker geometry controls chip flow in heavy-material applications
• Chamfered and honed cutting edge style reduces micro-chipping at entry and exit
• Positive rake angle reduces cutting forces in difficult-to-machine alloys including titanium and stainless
• ANSI and ISO dimensional compliance — ANSI code LNPU863ANSLHD, ISO code LNPU2410ANSLHD

Compatibility

Designed for use with MEGA45 series milling cutter bodies. Insert style LNPU, size code 863, left-hand orientation. Confirm cutter body pocket geometry and hand orientation before installation.

Installation Notes

Insert replacement should be performed by a qualified CNC machinist or tooling technician. Power down and lock out the spindle before accessing the cutter body. Use the correct Torx or hex key for the screw-lock retention system and follow the cutter body manufacturer torque guidance. Inspect the pocket seat for chips or wear before seating the new insert, as debris under the insert will affect runout and edge life.
