Kennametal 1937532 Boring Insert KC5010 Solid Carbide Tin

Product Description

The KENNAMETAL 1937532 is a solid carbide boring insert designed for precision internal turning and boring operations on CNC lathes and machining centers. This insert carries the TDHB12807501 designation and is manufactured to grade KC5010, a PVD-applied titanium nitride (TiN) coated micrograin carbide grade suited for finishing and semi-finishing cuts. The 60-degree triangular geometry provides three usable cutting edges per insert. With a 0.002 inch corner radius and a 15-degree relief angle, this insert is engineered for tight-tolerance bore finishing where controlled chip formation and dimensional accuracy are critical. Machinists and tool-and-die professionals working in high-precision bore applications will find this insert a direct fit for standard TDHB-style boring toolholders.

This insert is appropriate for light finishing passes in steel, stainless, and similar ferrous materials where the KC5010 TiN-coated micrograin carbide grade performs best. It seats in TDHB-style boring bar toolholders that accept a 5/32 inch inscribed circle triangular insert. Typical applications include bore sizing on close-tolerance hydraulic components, pump housings, and precision machined bores in both job shop and production environments. The insert is sold individually but requires a minimum order of 5 units per purchase.

Key Features

• KC5010 micrograin solid carbide grade with PVD titanium nitride coating for wear resistance on ferrous materials
• 60-degree triangular shape provides three cutting edges per insert, reducing per-edge cost
• 0.002 inch corner radius suited for fine surface finish requirements in tight-tolerance bores
• 15-degree relief angle reduces rubbing and supports clean cutting action in boring applications
• TDHB insert style with 5/32 inch inscribed circle and 0.095 inch hole diameter for positive toolholder seating
• Lightweight at 0.02 pounds, consistent with high-precision indexable insert construction

Compatibility

Designed for use in TDHB-style boring bar toolholders that accept a 5/32 inch inscribed circle triangular insert with a 0.095 inch mounting hole diameter and a 15-degree relief angle.

Installation Notes

Installation should be performed by a qualified machinist familiar with indexable insert toolholders. Ensure the boring bar and machine spindle are fully stopped and the machine is locked out before changing inserts. Use the appropriate torx or hex key to seat the insert clamp to the toolholder manufacturer's specified torque. Inspect the insert pocket and clamp for wear or debris before seating a new insert to ensure proper seating and runout control.
