Kennametal 1937615 Boring Insert TD6P5 KC5010 Solid Carbide

Product Description

The KENNAMETAL 1937615 is a solid carbide boring insert in the TD6P5 style, finished with a PVD-applied Titanium Nitride (TiN) coating and graded KC5010. Designed for internal boring operations, this triangular insert features a 60-degree included angle, a 3/8-inch inscribed circle, a 0.007-inch corner radius, and a thickness of 0.127 inches. The micrograin carbide substrate combined with the TiN coating supports extended tool life in precision boring applications. Licensed machinists and tooling technicians install this insert in compatible boring bars and toolholders for turning center and lathe operations.

This insert is suited for internal diameter boring on CNC lathes and turning centers in both production shop and job shop environments. The TD6P5 style and KC5010 grade make it appropriate for a range of ferrous and non-ferrous materials where a sharp, coated carbide edge is required. The 11-degree relief angle reduces cutting forces and helps maintain surface finish quality in finish and semi-finish boring passes. The 0.1300-inch hole diameter accommodates standard insert clamping screw systems used in precision boring toolholders.

Key Features

• Solid micrograin carbide substrate in manufacturer grade KC5010 for wear resistance
• PVD-applied Titanium Nitride coating for improved edge hardness and tool life
• 60-degree triangle shape (TD6P5 style) with 11-degree relief angle for reduced cutting force
• 3/8-inch inscribed circle (0.3750 inches) and 0.127-inch thickness for compact boring applications
• 0.007-inch corner radius for controlled surface finish in finish boring passes
• Clamp hole diameter of 0.1300 inches for compatibility with standard screw-clamp toolholders

Compatibility

Designed as an OEM-style replacement boring insert for toolholders and boring bars accepting TD6P5 style triangular carbide inserts with a 3/8-inch inscribed circle. Verify seat geometry, clamping screw size, and pocket relief angle against your toolholder specification before installation.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Power down and lock out the machine spindle before changing inserts. Use the correct insert clamping screw and appropriate torque wrench per the toolholder manufacturer specification. Inspect the insert pocket seat for wear, chips, or debris before seating the new insert, as a contaminated seat will affect runout and surface finish.
