Accupro 56465651 Lnku Milling Insert Size 12 Solid Carbide

Product Description

The ACCUPRO 56465651 is a solid carbide milling insert in the LNKU style, designed for use in indexable milling cutters on CNC and manual milling machines. It features a rectangular shape with a positive rake geometry and a PVD coating applied over the ACM40P manufacturer grade carbide substrate. The insert has a corner radius of 0.0315 inches (0.80 mm), a maximum depth of cut of 0.4724 inches (12.00 mm), and four usable cutting edges on a double-sided body. The ISO code for this insert is LNKU120608ERSCM. Machinists and tooling technicians working in production or job-shop environments install this insert as part of a compatible LNKU-series cutter body.

This insert is suited for milling operations where positive rake geometry reduces cutting forces and improves chip evacuation. The PVD coating provides wear resistance during medium to high-speed milling passes. With an inscribed circle diameter of 0.3937 inches (10.00 mm) and a thickness of 0.2669 inches (6.7800 mm), the insert fits LNKU-series cutter bodies in the CI series. It is appropriate for ferrous and non-ferrous material removal in both roughing and semi-finishing applications. Right-hand cutting orientation is standard on this part. The insert is secured in the cutter body using a screw-type holding method.

Key Features

• Solid carbide construction with ACM40P manufacturer grade for cutting performance and edge integrity
• PVD coating for improved wear resistance and extended tool life
• Double-sided insert with 4 cutting edges to maximize value per piece
• Positive rake geometry reduces cutting forces and improves chip flow
• Corner radius of 0.0315 inches (0.80 mm) for controlled surface finish
• Screw-type insert holding method for secure, repeatable positioning in the cutter body

Compatibility

Compatible with LNKU-series cutter bodies in the CI series, as indicated by the ISO code LNKU120608ERSCM. Designed as a direct-fit replacement for LNKU style indexable milling cutter bodies that accept size 12 inserts.

Installation Notes

Installation is performed by machinists or tooling technicians during planned insert indexing or replacement. Power down and lock out the machine spindle before removing or seating any insert. Use the appropriate torx or hex key driver specified by the cutter body manufacturer to tighten the clamping screw to the body manufacturers torque specification. Inspect the insert pocket seat for chips or debris before seating the new insert to ensure full contact and accurate positioning.
