Kennametal 1937580 Boring Insert TPCG2205 KC5010 Carbide

Product Description

The KENNAMETAL 1937580 is a solid carbide boring insert with a triangular geometry and a KC5010 manufacturer grade, designed for precision internal turning and boring operations on CNC and manual lathes. The insert features a PVD-applied Titanium Nitride (TiN) coating over a micrograin carbide substrate, delivering strong wear resistance and edge retention on a range of ferrous and non-ferrous workpiece materials. Key dimensional specs include a 1/4-inch inscribed circle, a 3/32-inch thickness, and a 0.007-inch corner radius. The left-hand configuration determines seating orientation in the toolholder. This insert is sold individually but must be ordered in multiples of five.

This insert is suited for light to medium boring and finishing passes in machine shop environments, both job shop and production floor settings. The 60-degree included angle and 11-degree relief angle make it appropriate for internal diameter work where clearance is limited. It is installed and indexed by machinists and tooling specialists working with compatible TPCG-style boring bars and toolholders. The TPCG2205 insert size code identifies the seating geometry and must match the toolholder pocket specification before installation.

Key Features

• Solid carbide micrograin substrate for consistent edge geometry and extended tool life
• PVD Titanium Nitride (TiN) coating for improved surface hardness and reduced built-up edge
• 60-degree triangular shape with 11-degree relief angle for positive clearance in boring applications
• 0.007-inch corner radius provides a balance between edge strength and surface finish quality
• Left-hand insert orientation for use with left-hand TPCG boring bar toolholders
• ISO code TOHH110202L for cross-reference and toolholder matching

Compatibility

Designed for use with TPCG-style boring bar toolholders that accept a 2205 insert size with a left-hand seating configuration. Verify toolholder pocket geometry and ISO code TOHH110202L compatibility before ordering.

Installation Notes

This insert is installed and indexed by qualified machinists or tooling technicians. Always power down and lock out the machine spindle before changing or indexing inserts. Use the appropriate torque wrench and insert screw specified by the toolholder manufacturer when securing the insert in the pocket — do not overtighten by hand. Inspect the toolholder pocket for wear, chips, or debris before seating a new insert to ensure proper support and accurate edge positioning.
