Sumitomo 1NT5007 Turning Insert CCGT32.51MESI-AC5015S Carbide

Product Description

The SUMITOMO 1NT5007 is a CCGT-style solid carbide turning insert designed for precision external turning and boring operations on CNC lathes and turning centers. Coated with TiAlSiN via a PVD process under Sumitomo's Absotech Bronze proprietary designation, this insert delivers wear resistance and thermal stability suited for demanding cutting applications. It features an 80-degree diamond insert shape, a 3/8-inch inscribed circle, and a 0.0156-inch corner radius. The neutral cutting direction and positive rake geometry at 15 degrees promote smooth chip flow. Licensed machinists and CNC operators install this insert in commercial and industrial machining environments.

This insert is engineered for turning powdered metal workpiece materials, classified under material grade S10. The MESI chip breaker geometry is suited to finishing and light semi-finishing passes where surface integrity is critical. With screw-type insert holding and a CCGT insert style, it fits standard CCGT-compatible toolholders. It is identified under ANSI code CCGT32.51MESI and ISO code CCGT09T304MN-SI, making cross-referencing with toolholder catalogs straightforward for machinists working across multiple machine platforms.

Key Features

• Solid carbide construction with TiAlSiN PVD coating (Absotech Bronze designation) for heat and wear resistance
• MESI chip breaker geometry optimized for finishing cuts on powdered metal materials
• 80-degree diamond insert shape with positive rake angle of 15 degrees for reduced cutting forces
• 0.0156-inch corner radius for tight-tolerance surface finishing
• Screw-type clamping method for secure, repeatable insert seating
• Dual standard identification: ANSI CCGT32.51MESI and ISO CCGT09T304MN-SI

Compatibility

Compatible with CCGT-style screw-clamp toolholders accepting a 3/8-inch inscribed circle insert. Identified by ANSI code CCGT32.51MESI and ISO code CCGT09T304MN-SI. Part of the Sumitomo AC5000S series.

Installation Notes

Installation is performed by licensed machinists or CNC setup technicians. Power down and lock out the machine spindle before changing inserts. Use the appropriate torx or hex wrench to seat the clamping screw to the toolholder manufacturer's specified method without over-torquing. Verify insert seating and runout before resuming cutting operations.
