Kyocera TKC89001 Indexable Drill Insert WCMX05M1A PR1230

Product Description

The KYOCERA TKC89001 is a WCMX-style indexable drill insert designed for use in indexable drill and coredrill toolholders. This solid carbide insert carries the PR1230 manufacturer grade with a PVD coating for extended wear resistance in steel cutting applications. The trigon (80-degree included angle) geometry features a positive rake angle and a 7-degree relief angle, promoting efficient chip evacuation and reduced cutting forces. With a 5/16-inch inscribed circle and a 1/8-inch thickness, this insert is sized for compact drill bodies targeting smaller-diameter bores. Installation is performed by qualified machinists and toolroom technicians.

This insert is intended for use in the KYOCERA Holeshot Drill and Coremaster Coredrill series toolholders. The M1A chipbreaker geometry is optimized for steel workpieces (ISO material group P), making it well-suited for through-hole and blind-hole drilling operations in ferrous materials. The right-hand cutting direction and positive rake design support clean entry and controlled chip flow in production and job-shop environments. A 1/32-inch corner radius provides a balance between edge strength and surface finish at the drilled hole entrance.

Compatibility

Designed for use in the KYOCERA Holeshot Drill and Coremaster Coredrill series toolholders. Verify toolholder seat geometry and insert size code 05 (insert size 50308) before installation. Compatible with right-hand cutting configurations targeting steel and ferrous workpiece materials (ISO P group).

Installation Notes

Insert seating and torquing should be performed by a qualified machinist or toolroom technician following the toolholder manufacturer's clamping procedure. Power down or lock out the machine spindle before changing inserts. Inspect the toolholder pocket for debris, wear, or damage before seating a new insert. Do not exceed the toolholder manufacturer's recommended speed and feed parameters for this insert grade and geometry.
