Kennametal 1937519 Boring Insert CDHH12061 KC5010 Carbide

Product Description

The KENNAMETAL 1937519 is a solid carbide boring insert in the CDHH style, designed for precision internal boring operations on CNC lathes and machining centers. It carries the KC5010 manufacturer grade, a micrograin carbide substrate with a PVD-applied Titanium Nitride (TiN) coating that extends wear resistance in demanding cutting applications. The insert features an 80-degree diamond shape with a 15-degree relief angle and a corner radius of 0.015 inches, making it well suited to finishing and semi-finishing passes where dimensional accuracy matters. Machinists and toolroom technicians specify this insert for its consistent edge geometry and carbide hardness across production runs.

This insert is intended for right-hand boring operations and fits into CDHH-series boring bar toolholders. It is commonly used in production machining environments handling ferrous and non-ferrous metals where a TiN-coated micrograin carbide grade delivers reliable performance. The 80-degree diamond shape provides a strong cutting edge while maintaining clearance geometry suited to internal diameter work in both manual and CNC setups.

Key Features

• Solid carbide micrograin substrate with PVD Titanium Nitride (TiN) coating for extended tool life
• 80-degree diamond shape with 15-degree relief angle for efficient internal boring
• Corner radius of 0.015 inches (1/64 inch) for controlled surface finish on finish and semi-finish passes
• Right-hand cutting orientation, CDHH insert style, Series C
• Inscribed circle of 0.156 inches (5/32 inch) and thickness of 0.040 inches for consistent holder seating
• Hole diameter of 0.083 inches for positive screw-on mounting in compatible toolholders

Compatibility

Designed as an OEM-style replacement or direct-fit insert for CDHH-series boring bar toolholders accepting a 5/32-inch inscribed circle, 80-degree diamond insert with a 0.083-inch mounting hole diameter.

Installation Notes

Insert installation should be performed by a qualified machinist or toolroom technician with the machine powered down and locked out per OSHA lockout/tagout procedures. Use a calibrated torque wrench and the insert manufacturer-specified clamping screw to seat the insert fully in the pocket without overtightening. Inspect the insert pocket and clamping components for chips or wear before seating a new insert. Always verify cutting direction and tool offset registration before resuming cutting operations.
