Seco 00077952 Grooving Insert CP500 Solid Carbide Snap Tap

Product Description

The SECO 00077952 is a solid carbide grooving insert designed for external threading and grooving operations on CNC lathes and turning centers. Running in the Snap Tap series, this insert carries the 9NR046FG geometry with a CP500 manufacturer grade and a PVD-applied TiAlN and TiN dual-layer coating for extended tool life across a broad range of workpiece materials. The cutting width measures 0.046 inches, matched by a maximum depth of cut of 0.046 inches. At 0.3543 inches overall length, the insert seats in size-9 toolholders using a clamp holding method. This insert is suited for production turning environments where consistent groove geometry and finish are required.

This insert is rated for universal primary workpiece material compatibility, covering ISO material groups H, K, M, N, O, P, and S. That range includes steels, stainless steels, cast irons, non-ferrous metals, and high-temperature alloys. The Snap Tap series designation makes it appropriate for both threading and grooving applications where a full-radius chip breaker profile is not required. Machinists and CNC lathe operators working in job shops or production facilities will find this insert fits standard Snap Tap toolholding systems. The FG chip breaker geometry supports fine-to-medium chip control across this material range.

Key Features

• CP500 micrograin solid carbide grade for wear resistance and edge stability
• PVD TiAlN and TiN dual coating extends tool life across ISO material groups H, K, M, N, O, P, and S
• 0.046 inch cutting width with 0.046 inch maximum depth of cut for precise groove sizing
• Right-hand cut orientation for standard CNC lathe setups
• Clamp-style insert holding in size-9 seat for secure, repeatable indexing
• FG chip breaker geometry without full radius for controlled chip formation

Compatibility

Designed for use with Snap Tap series size-9 toolholders that accept the 9NR insert style with a clamp holding method. Compatible with ISO-standard grooving and threading insert systems using a 0.25 inch inscribed circle. Verify toolholder specifications before installation.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before seating or indexing the insert. Use the appropriate torque wrench and clamp screw specified by the toolholder manufacturer to secure the insert — do not overtighten by hand estimation. Inspect the insert seat for chips or debris before clamping to ensure proper seating and prevent edge breakage on first cut.
