Kennametal 1785717 Turning Insert CNGP431 KC5410 Carbide

Product Description

The KENNAMETAL 1785717 is a solid carbide turning insert in the CNGP431 geometry, grade KC5410, designed for high-speed turning, facing, and boring of non-ferrous metals and aluminum. It carries a TiB2 coating applied via PVD process, which delivers high wear resistance while maintaining toughness suited to medium machining conditions. The insert features an 80-degree diamond (rhombic) shape, a neutral hand orientation, and a honed cutting edge style. With four usable cutting edges per insert and a negative rake and negative side clearance, this insert fits standard KENLOC-style clamp-and-pin toolholders used in production turning environments.

This insert is intended for machining non-ferrous metals, primarily aluminum and other N-group materials, across light-to-medium depth-of-cut applications. The KC5410 grade is rated for high wear resistance to moderate wear resistance with toughness, making it well-suited to production turning cells and CNC lathes handling aluminum components. Typical applications include external turning, facing passes, and light boring operations. The CNGP431 geometry follows both ANSI and ISO standards, allowing use on any compatible toolholder system accepting that insert form factor.

Key Features

• TiB2 PVD coating optimized for aluminum and non-ferrous metal cutting
• 80-degree diamond insert shape with negative rake and negative side clearance for stable clamping
• Four usable cutting edges per insert, reducing per-edge cost in production runs
• Honed cutting edge style reduces built-up edge on aluminum workpieces
• Maximum depth of cut of 0.049 inches (1.25 mm) suitable for medium machining passes
• Meets both ANSI and ISO standards (ANSI CNGP431, ISO CNGP120404)

Compatibility

Designed for use in KENLOC-series toolholders and any ANSI- or ISO-compliant clamp-and-pin turning toolholder accepting the CNGP431 insert geometry. Compatible with multi-use turning, facing, and boring operations on non-ferrous and aluminum workpieces. Insert holding method requires both clamp and pin retention.

Installation Notes

This insert is installed by a machinist or toolroom technician on a CNC or manual lathe using a KENLOC-compatible clamp-and-pin toolholder. Power down and lock out the spindle before seating or indexing any insert. Inspect the insert pocket and seating surfaces for chips or debris before installation, as contamination affects edge runout and tool life. Index only to undamaged cutting edges and discard the insert when all four edges show wear beyond acceptable limits.
