Kennametal 5651223 Milling Insert X400 Solid Carbide

Product Description

The KENNAMETAL 5651223 is a solid carbide milling insert in the X400 grade, designed for high-performance metal removal in milling applications. Carrying the ANSI/ISO designation XDLW120508SRD, this square-shaped insert features a TiAlN coating applied via PVD process, which provides thermal resistance and extended tool life when cutting steel and hard materials. It has 4 cutting edges, a positive rake geometry, and a right-hand cutting orientation. The insert measures 0.5 inches in length and width, with a thickness of 0.2189 inches and a corner radius of 0.0312 inches. Licensed technicians and tooling specialists install this insert into compatible milling cutter bodies as part of precision machining operations.

This insert is suited for milling steel and hard material workpiece categories, as indicated by material application codes P and H. The positive rake and chamfered, honed cutting edge style reduce cutting forces and improve surface finish on ferrous and hardened materials. The flat-top chip breaker geometry supports controlled chip evacuation in both roughing and semi-finishing passes. It is a single-sided insert held in place by a screw-clamping method at a 15-degree relief angle and a 90-degree included angle, making setup straightforward for experienced machine operators.

Key Features

• X400 grade solid carbide construction with PVD TiAlN coating for thermal and wear resistance
• Square insert shape (XDLW series) with 4 usable cutting edges per insert
• Positive rake geometry with chamfered and honed cutting edge for reduced cutting forces
• Flat-top chip breaker for controlled chip flow in steel and hard material applications
• Right-hand cut orientation with screw-type insert holding method
• Conforms to ANSI and ISO standards; ANSI/ISO code XDLW120508SRD

Compatibility

Compatible with the 7792VXD12 cutter series. Designed as an OEM-style replacement or direct-fit insert for milling cutter bodies that accept the XDLW120508SRD insert style.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician with the machine fully powered down and spindle locked before changing inserts. Use the manufacturer-specified torx or hex key to seat the clamping screw to the cutter body specification — do not overtighten, as this can fracture the carbide body. Inspect the pocket seat and clamping hardware for wear or debris before installing a new insert. Follow applicable shop safety protocols and machine tool manufacturer guidelines during all insert indexing procedures.
