Kyocera TKB09487 Indexable Drill Insert ZCMT12SP PR1225

Product Description

The KYOCERA TKB09487 is an indexable drill insert designed for use in indexable drill bodies operating in metal cutting applications. It carries the ZCMT12SP insert style with manufacturer grade PR1225, a PVD-applied MEGACOAT coating on a solid carbide micrograin substrate. The diamond shape and positive rake geometry promote clean chip formation and reduced cutting forces. With four cutting edges per insert and a 0.40 mm corner radius, this insert delivers consistent performance across multiple index positions before replacement. It is installed by machinists and tool-crib technicians in CNC drilling operations targeting stainless steel and steel workpieces.

This insert is suited for production and job-shop drilling environments where stainless steel is the primary workpiece material and carbon or alloy steel is the secondary material. The SP chipbreaker geometry is engineered for chip control in these demanding materials. The DRZ series insert fits indexable drill bodies that accept the ZCMT12T304SP seat geometry. Right-hand cutting direction makes it compatible with standard clockwise-spindle setups found on CNC machining centers and drill presses.

Key Features

• Solid carbide micrograin substrate for high wear resistance in stainless steel and steel cutting
• PVD MEGACOAT coating for extended tool life and reduced built-up edge
• Diamond insert shape with 7-degree relief angle and positive rake for lower cutting forces
• SP chipbreaker for effective chip control in tough materials
• Four usable cutting edges per insert to maximize value per piece
• Conforms to ANSI code ZCMT12T304SP PR1225 and ISO code ZCMT12T304SP

Compatibility

Designed as a replacement insert for indexable drill bodies accepting the ZCMT12T304SP seat geometry in the DRZ series. ANSI code ZCMT12T304SP PR1225 and ISO code ZCMT12T304SP confirm seat and grade interchangeability with compatible toolholders.

Installation Notes

Insert installation and indexing should be performed by qualified machinists or tool-crib personnel with the machine spindle fully stopped and locked out per OSHA lockout/tagout procedures. Use a calibrated torque wrench and the correct Torx or hex key for the clamping screw to avoid seat damage. Inspect the pocket seat and clamping screw for wear or contamination before seating a new index position. Do not force the insert into the pocket; proper seating is confirmed when the insert lies flush against all pocket walls.
