Kennametal 1868453 Turning Insert DNGP431 KC5010 Carbide

Product Description

The KENNAMETAL 1868453 is a solid carbide turning insert with ANSI designation DNGP431 and ISO designation DNGP150404, manufactured in the KC5010 grade. It features a PVD-applied TiAlN coating that delivers high wear resistance across a range of primary workpiece materials including steel, stainless steel, cast iron, superalloys, and titanium. The insert has a 55-degree diamond (rhombic) shape, a neutral hand orientation, and a 0.5-inch inscribed circle. Corner radius measures 0.0156 inches (1/64 inch), and insert length is 15.5 mm (approximately 1.221 decimal inches). This insert is part of the KENLOC series and is designed for use by machinists and CNC lathe operators in precision turning applications.

The KENNAMETAL 1868453 is suited for medium machining operations including turning, facing, boring, back turning, and back boring. Its KC5010 grade is engineered to maintain high to moderate wear resistance and toughness when cutting steel (P), stainless steel (M), cast iron (K), aluminum (N), and superalloys and titanium (S). The negative rake geometry and honed cutting edge provide stable, controlled chip formation in both roughing passes at shallow depths and consistent finish passes. Maximum depth of cut is 1.25 mm (0.0492 inches). This insert is a multi-use tool appropriate for production turning environments where insert longevity and consistent surface finish are priorities.

Key Features

• KC5010 grade with PVD TiAlN coating for high wear resistance on steel, stainless steel, cast iron, superalloys, and titanium
• 55-degree diamond (D-style) insert shape with neutral hand — compatible with KENLOC toolholders using clamp and pin retention
• 4 cutting edges per insert, maximizing cost-per-edge value in production turning
• Honed cutting edge with negative rake angle for stable chip control during medium machining operations
• Maximum depth of cut 1.25 mm (0.0492 inches) with common chip breaker geometry for medium material removal rates
• Meets ANSI and ISO dimensional standards; ANSI size code 431, ISO size code 150404

Compatibility

Designed for use in KENLOC series toolholders that accept DNGP-style inserts with clamp and pin holding methods. Compatible with toolholders specifying a 0.5-inch inscribed circle, 3/16-inch insert thickness, and negative side clearance (N tolerance, G clearance code). Verify toolholder specifications before ordering.

Installation Notes

Installation is performed by a qualified machinist or CNC lathe operator. Power down and lock out the machine spindle before seating or removing the insert. Use the appropriate KENLOC clamp and pin hardware to secure the insert; do not overtighten or substitute non-OEM clamping components. Inspect the pocket seat and clamp surfaces for chips or debris before installing a fresh insert edge.
