Seco 02952786 Grooving Insert CP500 Solid Carbide X4

Product Description

The SECO 02952786 is a solid carbide grooving insert designed for external grooving and parting operations on CNC lathes and turning centers. It carries the X4GKR2503005MC designation and is coated with a PVD-applied TiAlN and TiN finish for improved wear resistance and heat resistance at the cutting edge. The insert delivers a 1.5 mm cutting width and a maximum depth of cut of 6.5 mm. A positive rake angle of 6 degrees and a 15-degree lead angle reduce cutting forces and help control chip formation across a broad range of workpiece materials. Installation requires a compatible X4-series grooving toolholder. This insert is intended for use by machinists, toolroom technicians, and CNC operators in production and job-shop environments.

The 02952786 is rated for universal primary workpiece material application, covering material groups H, K, M, N, O, P, and S under ISO classification. This makes it suitable for grooving carbon steels, stainless steels, cast irons, non-ferrous alloys, hardened materials, and superalloys. The MC chip breaker geometry is engineered to manage chip evacuation across this wide material range. With a double-end configuration, the insert offers two usable cutting edges per piece, extending tool life between changeovers. The X4 series is designed for indexable insert grooving systems common in medium-production turning applications.

Key Features

• Solid carbide substrate with PVD-applied TiAlN and TiN dual-layer coating for thermal and wear resistance
• 1.5 mm cutting width with a maximum depth of cut of 6.5 mm
• Positive rake angle (6 degrees) and 15-degree lead angle reduce cutting forces
• MC chip breaker geometry supports controlled chip formation across universal workpiece materials
• Double-end insert provides two usable cutting edges per insert
• 0.05 mm corner radius minimizes stress concentration at the cutting edge
• ISO-compliant insert geometry; compatible with X4-series toolholding systems

Compatibility

Designed for use with X4-series indexable grooving toolholders that accept the X4GKR insert style and the 2503005 insert size code. Verify toolholder compatibility with the specific insert seat geometry before installation.

Installation Notes

This insert is installed and indexed by a qualified machinist or CNC toolroom technician. Power down and lock out the machine spindle before changing or indexing any insert. Seat the insert fully and evenly in the toolholder pocket and secure the clamping mechanism to the toolholder manufacturer's specified procedure before resuming cutting. Inspect the cutting edge and seating surface for chips or debris before each indexing to prevent insert rocking and premature failure.
