Ingersoll Cutting Tools 6308770 Carbide Cutoff Insert TSC4

Product Description

The INGERSOLL CUTTING TOOLS 6308770 is a solid carbide cutoff and grooving insert in the TSC series, designed for precision parting and grooving operations on CNC turning centers and lathes. It carries manufacturer grade TT8020 with a PVD-applied TiCN coating, delivering consistent wear resistance and edge integrity on steel and stainless steel workpieces. The insert features a right-hand cutting direction, a 4-degree lead angle, and a 7-degree relief angle. Cutting width measures 0.1575 inches and overall length is 0.790 inches. Clamp-style holding keeps the insert securely seated during interrupted cuts and high-feed passes.

This insert is suited for production turning environments where repeatable groove width and clean parting are required. It targets steel and stainless steel applications, covering ISO material codes P and M. The chipbreaker style is C, which manages chip flow in continuous and semi-continuous cuts. The single-end configuration means the cutting edge is located on one side only. With an ANSI and ISO code of TSC4-4R, it fits TSC-series toolholders designed for size 4 insert seats. Machinists and CNC operators working in job shops or high-volume production facilities are the primary users.

Compatibility

Designed for use in TSC-series clamp-style toolholders accepting a size 4 insert seat. ANSI and ISO code TSC4-4R should be used to confirm toolholder fitment 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 removing the insert. Ensure the insert pocket and clamping surfaces are clean and free of chips before seating the insert. Verify torque on the clamp screw per the toolholder manufacturer specification and confirm cutting direction matches the machine setup before starting the spindle.
