Seco 02754787 Turning Insert Ccmt 21.50.5 CP500 Carbide

Product Description

The SECO 02754787 is a solid carbide turning insert designed for precision finishing operations on a variety of workpiece materials. Conforming to ANSI insert code CCMT21.50.5 and ISO code CCMT060202, this insert features an 80-degree diamond (rhombic) shape with a positive rake and positive side clearance. It is coated with a multilayer TiAlN and TiN PVD coating under the CP500 grade, providing a balance of moderate to high wear resistance and toughness. The MF2 chip breaker geometry is optimized for finishing cuts. The inscribed circle measures 0.25 inches and the corner radius is 0.0079 inches. Licensed machinists and CNC operators install this insert in screw-held toolholders for turning, facing, and boring applications.

This insert is suited for finishing passes on stainless steel, steel, cast iron, superalloys, and titanium workpieces. The CP500 grade with PVD multilayer coating is rated for material groups P, K, and S, covering a wide range of ferrous and difficult-to-machine materials. It is appropriate for both manual engine lathes and CNC turning centers in job shop, production, and aerospace environments. Each insert provides two usable cutting edges, and the neutral hand orientation allows flexible toolholder compatibility. The MF2 chip breaker promotes controlled chip evacuation during light to moderate finishing depths of cut.

Key Features

• CP500 grade with multilayer TiAlN and TiN PVD coating for wear resistance across P, K, and S material groups
• MF2 chip breaker geometry engineered for finishing operations with controlled chip flow
• 80-degree diamond insert shape with positive rake and 7-degree relief angle for reduced cutting forces
• Two usable cutting edges per insert for extended tool life and lower cost per edge
• Screw-held mounting method with neutral hand for broad toolholder compatibility
• Chamfered and honed cutting edge style for edge stability on hard and abrasive workpiece materials

Compatibility

Designed to fit toolholders accepting CCMT21.50.5 (ANSI) or CCMT060202 (ISO) inserts with screw clamping. Suitable for turning, facing, and boring operations. Compatible with SECO CCMT-MF2 series tooling systems as stated by the manufacturer.

Installation Notes

Installation is performed by machining professionals or CNC setup technicians. Power down and lock out the machine before changing inserts. Seat the insert fully against the toolholder pocket and torque the clamping screw according to the toolholder manufacturer specification. Inspect the insert pocket for chips or wear before seating a new insert to ensure proper contact and edge alignment.
