Kyocera TKB09485 Indexable Drill Insert ZCMT08SP PR1225

Product Description

The KYOCERA TKB09485 is a solid carbide indexable drill insert designed for high-performance drilling applications in stainless steel and steel workpieces. Manufactured to ANSI and ISO standards under ANSI code ZCMT080304SP PR1225, this insert features a diamond shape with a positive rake angle and a 7-degree relief angle. The PR1225 manufacturer grade with PVD coating and micrograin carbide substrate delivers wear resistance and edge retention in demanding cutting environments. With four cutting edges per insert, it maximizes tool life and reduces per-edge tooling cost for production drilling operations.

This insert fits the KYOCERA DRZ series indexable drill system and is suited for drilling stainless steel (material code M) as primary workpiece material and steel (material code P) as secondary workpiece material. It is intended for right-hand cutting direction. Typical installation scenarios include CNC machining centers and turning centers in precision manufacturing, job shops, and aerospace or medical fabrication environments where stainless steel drilling is routine. The SP chipbreaker geometry supports chip control in these materials.

Key Features

• Diamond (ZCMT) insert shape with positive rake for reduced cutting forces in stainless steel and steel
• PR1225 grade with PVD coating on micrograin solid carbide substrate for wear resistance and edge toughness
• SP chipbreaker geometry designed for controlled chip evacuation in stainless and steel drilling
• Four usable cutting edges per insert to reduce tooling cost per hole
• Conforms to ANSI code ZCMT080304SP PR1225 and ISO code ZCMT080304SP for verified fitment
• Right-hand cutting direction with 7-degree relief angle for positive clearance

Compatibility

Designed for use in the KYOCERA DRZ series indexable drill system. Insert size code 08, series DRZ. Verify seating compatibility with the specific DRZ drill body before installation.

Installation Notes

Insert replacement should be performed by a qualified machinist or tooling technician. Power down and lock out the machine spindle before accessing the tool body. Use the appropriate torque wrench and KYOCERA-specified clamping screws when seating the insert; do not overtighten or substitute fasteners. Inspect the insert pocket for damage or debris before installing a new insert to ensure proper seating and runout.
