Sandvik Coromant 7080751 Turning Insert Dcmt Coroturn 107

Product Description

The SANDVIK COROMANT 7080751 is a solid carbide turning insert in the DCMT style, designed for precision external turning operations on CNC lathes and turning centers. Part of the CoroTurn 107 series, this insert carries a multilayer CVD coating of TiCN, Al2O3, and TiN, optimizing performance on steel workpieces. The 55-degree diamond insert shape provides a sharp, pointed geometry suited for profiling and finishing passes. The neutral hand orientation allows use in standard right-hand toolholders. With a 3/8-inch inscribed circle and a 1/32-inch corner radius, this insert delivers controlled chip formation through its UM chip breaker geometry. Installation requires a compatible screw-lock toolholder accepting DCMT 11 T3 08 inserts.

The 7080751 is intended for turning steel in light-to-medium finishing and semi-finishing applications. The UM chip breaker is engineered for low-to-medium depth-of-cut passes on steels classified under ISO material group P. It is commonly used by CNC machinists and production turning shops running both short-run and high-volume parts where surface finish and dimensional accuracy are priorities. This insert is sold individually and is compatible with screw-type DCMT toolholders as part of the CoroTurn 107 tooling system.

Key Features

• CVD multilayer coating: TiCN, Al2O3, and TiN for wear resistance on steel
• DCMT 55-degree diamond insert shape for profiling and contour turning
• UM chip breaker geometry optimized for finishing passes on ISO P steels
• Neutral hand insert suitable for standard right-hand screw-lock toolholders
• 3/8-inch inscribed circle with 1/32-inch corner radius for controlled nose geometry
• Two cutting edges per insert to maximize tool life per unit

Compatibility

Designed for use with screw-lock DCMT-style toolholders in the CoroTurn 107 system. ISO code DCMT 11 T3 08-UM 4335 identifies the insert for toolholder matching. Intended for primary use on steel workpieces under ISO material group P.

Installation Notes

This insert is seated and secured using the screw-lock (hole diameter 0.1732 inches) clamping method standard to DCMT toolholders. Power down the machine and follow lockout/tagout procedures before changing inserts. Seat the insert firmly and evenly in the pocket before tightening the clamping screw to avoid chipping the cutting edge. Inspect the insert pocket and seating surface for wear or debris before each insert change.
