Accupro 56465446 Milling Insert Solid Carbide Lnku Size 12

Product Description

The ACCUPRO 56465446 is a solid carbide milling insert designed for indexable face and shoulder milling operations. Manufactured in the LNKU insert style with an ISO code of LNKU120608ERHCM, this double-sided insert provides four usable cutting edges per insert, reducing tooling cost per edge. The ACP30M manufacturer grade features a CVD coating and is ground to a positive rake geometry with a 0-degree relief angle. The corner radius measures 0.0315 inches (0.80 mm), and the maximum depth of cut reaches 0.4724 inches (12.00 mm). Installation is performed by screw-holding method into compatible LNKU-series cutter bodies.

This insert is suited for milling applications in metalworking environments, including roughing and semi-finishing passes on ferrous and non-ferrous workpiece materials. The right-hand cutting orientation and positive rake geometry reduce cutting forces, making this insert appropriate for both horizontal and vertical machining centers. Machinists and CNC operators in job shops, production facilities, and maintenance machining environments will find this insert applicable to a wide range of milling programs. It is sold individually and requires a minimum order quantity of 10 units per order.

Key Features

• Double-sided insert with 4 cutting edges per insert for extended tool life
• CVD coating over solid carbide substrate for wear resistance in milling
• Positive rake geometry reduces cutting forces and heat generation
• Screw-holding retention method provides secure seating in the cutter body
• Corner radius of 0.0315 inches (0.80 mm) for controlled edge transition
• Maximum depth of cut of 0.4724 inches (12.00 mm) per pass

Compatibility

Designed for use with LNKU-series cutter bodies compatible with CI-series tooling. Cutter series compatibility is listed as LNKU. Confirm cutter body pocket geometry and screw size before installation.

Installation Notes

Insert installation should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before indexing or replacing inserts. Use the correct torx or hex key driver to seat the clamping screw to the cutter body manufacturer specification — do not overtighten. Inspect the pocket seating surface for chips or debris before installing a fresh insert edge.
