Seco 00099407 Turning Insert CCMT21.52-F1 CP500 Carbide

Product Description

The SECO 00099407 is a solid carbide turning insert in the CCMT-F1 series, designed for precision finishing operations in CNC and manual turning applications. It carries a multilayer PVD coating of TiAlN and TiN, providing wear resistance and thermal stability across a range of workpiece materials. The insert features an 80-degree diamond (rhombic) shape with a 0.25-inch inscribed circle, a 1/32-inch corner radius, and a positive rake geometry with positive side clearance. The F1 chip breaker is optimized for finishing cuts, producing controlled chip formation at light depths of cut up to 0.2205 inches.

This insert is suited for finishing passes on stainless steel, steel, cast iron, superalloys, and titanium in both boring, facing, and turning operations. The neutral hand orientation and screw-holding method make it compatible with standard CCMT-style toolholders used in production and job-shop environments. It is appropriate for light-duty material removal where surface finish and dimensional accuracy are the primary objectives. Machinists working with difficult-to-machine alloys will find the CP500 grade useful across moderate to high toughness demands as classified under material grades M10, M20, and M30.

Key Features

• CP500 grade with multilayer PVD TiAlN and TiN coating for wear resistance across steel, cast iron, and superalloy applications
• 80-degree diamond insert shape with sharp cutting edge style for precise finishing cuts
• F1 chip breaker geometry engineered for finishing operations with controlled chip evacuation
• Positive rake and positive side clearance for reduced cutting forces on difficult materials
• Two cutting edges per insert; screw-held, neutral hand orientation
• Conforms to ANSI code CCMT21.52 and ISO code CCMT060208 for standardized toolholder fit

Compatibility

Designed for use in standard CCMT-style toolholders accepting a 0.25-inch inscribed circle insert with screw clamping. Conforms to ANSI insert code CCMT21.52 and ISO insert code CCMT060208, ensuring fit with any compliant holder to those standards. Suitable for multi-use applications including boring, facing, and turning on CNC lathes and machining centers.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician with the machine in a de-energized and locked-out state before changing inserts. Use the appropriate torx or hex key for the clamping screw specified by the toolholder manufacturer; do not overtighten, as this can fracture the carbide insert. Verify seating of the insert in the pocket before resuming cuts, and inspect the cutting edge for chipping after initial passes on hard or abrasive workpiece materials.
