Kennametal 1874248 Milling Insert MDHX1004ZDFRGD4W K110M

Product Description

The KENNAMETAL 1874248 is a solid carbide milling insert identified by ANSI/ISO code MDHX1004ZDFRGD4W, manufactured in grade K110M with a bright uncoated finish. This parallelogram-style insert features a positive rake geometry, a 15-degree relief angle, and a wiper cutting edge style that supports improved surface finish in milling operations. With four cutting edges and a maximum depth of cut of 0.4331 inches, it delivers efficient material removal. The insert mounts via screw-holding method and is designed for use in Fix-Perfect cutter series tooling systems. It is installed and tooled by machinists and CNC operators in production and job-shop environments.

This insert is engineered for milling applications in cast iron and non-ferrous metals, corresponding to material grade codes K and N. The GD chip breaker geometry is suited to the controlled chip formation demands of these materials. Typical applications include face milling, shoulder milling, and finish passes on cast iron components and non-ferrous workpieces such as aluminum and copper alloys. The single-sided design and right-hand orientation define its setup in compatible MDHX-series Fix-Perfect milling cutters. This insert is a multi-use tool intended for repeated indexing across all four cutting edges before replacement.

Key Features

• Solid carbide K110M grade — uncoated bright finish suited for cast iron and non-ferrous metal cutting
• Wiper cutting edge style with GD chip breaker for improved surface finish and chip control
• Four indexable cutting edges per insert for extended tool life per unit
• Positive rake, 15-degree relief angle geometry reduces cutting forces on workpiece
• Maximum depth of cut of 0.4331 inches supports aggressive material removal passes
• Screw-mount insert holding method ensures secure, repeatable seating in Fix-Perfect cutter bodies

Compatibility

Compatible with MDHX-series Fix-Perfect milling cutter bodies. ANSI and ISO insert code MDHX1004ZDFRGD4W confirms fitment. Inscribed circle of 0.4252 inches falls within the 0.4000 to 0.5000 inch inscribed circle range for this insert size code (1004).

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Ensure the machine spindle is fully stopped and the cutter body is secured before indexing or replacing inserts. Use the appropriate Torx or hex key as specified by the cutter body manufacturer to seat the clamping screw — do not overtighten or cross-thread. Inspect the insert pocket seating surface for chips or debris before mounting to ensure proper insert contact and runout.
