Ingersoll Cutting Tools 6241355 Cpmt Turning Insert

Product Description

The INGERSOLL CUTTING TOOLS 6241355 is a solid carbide CPMT-style turning insert designed for precision metal cutting operations on steel workpieces. It features a diamond-shaped insert body with an 80-degree included angle and a neutral hand orientation, making it suitable for a wide range of turning applications. The insert carries a TT8125B manufacturer grade with a CVD-applied triple-layer coating of TiCN, Al2O3, and TiN, which provides thermal resistance and extended tool life during continuous or interrupted steel cuts. A screw-mounted holding method secures the insert firmly in compatible toolholders. Licensed machinists and CNC operators working in job shops or production environments are the primary installers of this insert.

This insert is intended for turning steel workpieces in both roughing and finishing passes where controlled chip formation is required. The PC chip breaker geometry promotes positive rake cutting action, helping to manage chip flow and reduce cutting forces. With a maximum depth of cut of 0.118 inches and an inscribed circle of 0.375 inches, it fits standard CPMT toolholder pockets and suits light-to-moderate material removal rates on lathes and turning centers. Its ANSI code is CPMT32.51PCTT8125B and ISO code is CPMT09T304PC TT8125B.

Key Features

• Solid carbide construction with CVD-applied TiCN, Al2O3, and TiN triple-layer coating for heat and wear resistance
• Diamond insert shape with 80-degree included angle and 11-degree relief angle for controlled edge engagement
• PC chip breaker with positive rake promotes efficient chip control on steel
• Neutral hand orientation for flexible toolholder compatibility
• Screw-mount holding method (clearance code P, tolerance code M) for secure seating and repeatable indexing
• 2 cutting edges per insert for extended service life

Compatibility

Designed to fit standard CPMT-series toolholder pockets per ANSI code CPMT32.51PCTT8125B and ISO code CPMT09T304PC TT8125B. Primary workpiece material designation is steel (material code P). No additional model-specific compatibility data was provided in the source input.

Installation Notes

Insert installation and indexing should be performed by a qualified machinist or CNC tooling technician with the machine fully powered down and the spindle locked before handling toolholders. Use the correct Torx or hex key specified by the toolholder manufacturer when tightening the clamping screw - do not overtighten, as this can fracture the carbide body. Inspect the toolholder pocket and seating surface for debris or damage before installing a fresh insert. Follow the toolholder manufacturer's recommended torque procedures and verify insert seating before resuming cutting operations.
