Kennametal 1832318 Turning Insert DNMG431MP KC5010 Carbide

Product Description

The KENNAMETAL 1832318 is a solid carbide turning insert in the DNMG431MP geometry, coated with TiAlN via a PVD process and manufactured to the KC5010 grade. It carries a 55-degree diamond shape with a neutral hand orientation and a 1/64-inch corner radius. The insert measures 15.50 mm (1.2208 inches) in length with a 1/2-inch inscribed circle and 3/16-inch thickness. Four cutting edges are available per insert, making it a cost-effective tooling option for production environments. It belongs to the KENLOC series and is designed for demanding material removal applications where edge wear resistance is critical.

This insert is suited for turning, facing, boring, back turning, and back boring operations on steel, stainless steel, superalloys, and titanium. The MP chip breaker geometry and chamfered-and-honed cutting edge style are optimized for medium-duty passes where chip control and edge stability are priorities. The negative rake angle and PVD TiAlN coating work together to extend tool life when cutting ISO material groups P, M, and S. It is a multi-use insert appropriate for both roughing and finishing passes within its maximum depth-of-cut range.

Key Features

• MP chip breaker geometry for reliable chip control during medium-duty operations
• 55-degree diamond insert shape (DNMG) with neutral hand for versatile setup configurations
• Four usable cutting edges per insert to reduce per-edge tooling cost
• Chamfered and honed cutting edge style for improved edge stability under load
• Maximum depth of cut of 1.25 mm (0.0492 inches) suitable for finish to semi-finish passes

Compatibility

Designed for use in KENLOC-series toolholders accepting DNMG-style inserts with clamp and pin holding method. Compatible with standard ANSI and ISO tooling systems. Verify toolholder pocket geometry and insert size code 431 before installation.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before seating or replacing the insert. Use the appropriate torque wrench and clamp hardware specified for the KENLOC toolholder to avoid insert movement or chipping during cuts. Inspect the pocket seat and clamp pin for wear before installing a new insert to ensure proper seating.
