Sandvik Coromant 5730468 Turning Insert DCET32.50-UM 1125

Product Description

The SANDVIK COROMANT 5730468 is a solid carbide turning insert in the CoroTurn 107 series, designed for precision external and internal turning operations on CNC lathes. The insert carries a 55-degree diamond shape (DCET style) with a neutral hand orientation and a 7-degree relief angle, making it well-suited for profiling and finishing cuts in tight-clearance applications. The TiAlN and AlCr2O3 dual-layer coating applied via PVD process provides thermal resistance and wear protection during continuous cutting cycles. With a 0.0079-inch corner radius and two cutting edges per insert, this grade 1125 insert delivers consistent surface finish on steel and stainless steel workpieces.

This insert is intended for use in screw-clamp toolholders compatible with the CoroTurn 107 insert system. Primary workpiece material is steel (ISO code P), with secondary application in stainless steel (ISO code M). Typical install scenarios include finishing passes on turned components where low cutting forces and close-tolerance geometry are required. The insert conforms to ISO designation DCET 11 T3 02-UM 1125 and is selected by machinists and CNC operators in job shops and production turning environments.

Key Features

• 55-degree diamond insert shape with DCET geometry for profiling and finishing
• TiAlN and AlCr2O3 PVD coating for wear resistance and thermal stability
• 0.0079-inch (0.20 mm) corner radius for tight-tolerance finishing cuts
• Neutral hand orientation compatible with standard CoroTurn 107 screw-clamp holders
• Two cutting edges per insert reduce per-edge tooling cost
• UM chip breaker geometry suited for steel and stainless steel turning

Compatibility

Designed for use in screw-clamp toolholders built to the CoroTurn 107 system standard, with a 4.40 mm hole diameter for insert retention. Compatible with steel (ISO P) and stainless steel (ISO M) workpiece materials per the manufacturer grade 1125 specification.

Installation Notes

Installation is performed by CNC machinists and tool-setup technicians. The machine spindle must be stopped and all motion axes must be locked before changing inserts. Use the appropriate Torx or hex key for the clamp screw and avoid overtightening, which can crack the carbide body. Inspect the toolholder seat and clamp for chips or debris before seating the new insert to ensure proper edge registration.
