Kennametal 5698301 VBMT332LF KCK15B Turning Insert Carbide

Product Description

The KENNAMETAL 5698301 is a solid carbide turning insert carrying the VBMT332LF geometry and KCK15B grade designation. It features a multilayer CVD coating system consisting of TiCN, Al2O3, and TiOCN applied via MT-CVD process, delivering wear resistance and thermal stability during continuous cutting operations. The 35-degree diamond shape (VBMT insert style) provides a sharp, low-force cutting geometry suited to finish and semi-finish turning. With an inscribed circle of 0.375 inches, an insert length of 16.61 mm (approximately 0.654 inches per half-length reference), and a corner radius of 0.0313 inches (1/32 inch), this insert is sized for moderate material removal on steel and cast iron workpieces. It is installed by licensed machinists and CNC operators in production turning environments.

This insert is designed for external and internal turning applications including facing, boring, back turning, and back boring on steel and cast iron materials (ISO material codes P and K). The LF chip breaker geometry promotes efficient chip control during light-to-moderate finish turning passes. The neutral hand orientation and screw-on holding method make it compatible with standard VBMT-style toolholders used in CNC lathes and turning centers across both job shop and production environments.

Key Features

• Multilayer CVD coating (TiCN / Al2O3 / TiOCN) for extended tool life on steel and cast iron
• 35-degree diamond insert shape (VBMT) with positive rake angle for reduced cutting forces
• LF chip breaker geometry optimized for finish and semi-finish turning operations
• Honed cutting edge style for edge stability and consistent surface finish
• Screw-on insert holding method for secure, repeatable indexing in compatible toolholders
• Two cutting edges per insert; neutral hand for versatile toolholder compatibility
• Rated for turning, facing, boring, back turning, and back boring applications

Compatibility

Designed for use in VBMT-style screw-on toolholders. Primary workpiece materials are steel (ISO P) and cast iron (ISO K). Conforms to ANSI and ISO standards for VBMT332 insert geometry. Material grades C3 and C4 apply.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Ensure the machine spindle is fully stopped and the turret is de-energized before indexing or replacing inserts. Use the correct torque driver for the screw-on clamp screw to avoid insert movement or screw damage during operation. Verify toolholder pocket cleanliness and seating surface condition before securing the insert to maintain dimensional accuracy.
