Kyocera TKB09475 Indexable Drill Insert PR1225 Carbide

Product Description

The KYOCERA TKB09475 is an indexable drill insert designed for use in indexable drill tooling systems where precise, repeatable hole-making is required. This insert features a diamond (ZCMT) shape with a PVD-coated solid carbide construction in the PR1225 manufacturer grade, which is formulated for cutting stainless steel and steel workpieces. With 4 cutting edges and a positive rake geometry, it delivers efficient chip evacuation and reduced cutting forces. The insert carries ANSI code ZCMT150408 PR1225 and ISO code ZCMT150408, confirming its conformance to recognized industry standards. It is installed and replaced by machinists and toolroom professionals as part of routine insert indexing maintenance.

This insert is intended for use in compatible KYOCERA DRZ-series indexable drills operating on CNC machining centers, turning centers, or drill presses in production and job-shop environments. It is primarily rated for stainless steel (material code M) and steel (material code P) workpiece materials, making it well suited for general metalworking, aerospace component machining, and industrial manufacturing applications where consistent bore quality is essential.

Key Features

• Diamond (ZCMT) insert shape with 4 indexable cutting edges for maximum insert utilization
• PR1225 grade PVD-coated solid carbide construction engineered for stainless steel and steel cutting
• Positive rake geometry reduces cutting forces and improves chip flow
• 7-degree relief angle provides clearance and minimizes flank wear
• Micrograin carbide substrate delivers toughness and edge stability under interrupted cuts
• Conforms to ANSI and ISO standards (ANSI: ZCMT150408 PR1225 / ISO: ZCMT150408)

Compatibility

Designed for use in KYOCERA DRZ-series indexable drill bodies that accept ZCMT150408 insert geometry. Confirm drill body insert seat specification before ordering.

Installation Notes

Insert indexing and replacement should be performed by a qualified machinist with the machine in a full stop, de-energized, and locked out per OSHA lockout/tagout procedures. Use a calibrated torque wrench and the correct Torx or hex key as specified by the drill body manufacturer for insert clamping screws. Inspect the insert pocket seat for debris or damage before seating a new insert. Do not use damaged inserts or re-grind indexable inserts.
