Sandvik Coromant 5730472 Turning Insert DCET32.51-UM 1105

Product Description

The SANDVIK COROMANT 5730472 is a solid carbide turning insert in a 55-degree diamond shape, designed for precision external turning operations on CNC lathes and turning centers. Designated as DCET32.51-UM 1105 and part of the CoroTurn 107 series, this insert features a TiAlN coating applied via PVD process for improved wear resistance and thermal stability. It carries a 0.3750-inch inscribed circle, a 0.0156-inch corner radius, and an insert length of 0.4420 inches. The UM chip breaker geometry is optimized for light to medium finishing cuts. Machining professionals and CNC operators install this insert in screw-clamp toolholders for high-tolerance turning work on steel and stainless steel workpieces.

This insert is suited for finishing and semi-finishing applications on steel (ISO P) and stainless steel (ISO M) materials. The DCET style with a 7-degree relief angle and neutral hand orientation makes it well-suited for external turning and profiling where clearance geometry is critical. The CoroTurn 107 series is engineered for close-tolerance work in precision component manufacturing environments, including aerospace, medical, and general machining shops. The ISO designation for this insert is DCET 11 T3 04-UM 1105.

Key Features

• 55-degree diamond insert shape (ISO shape code D) for profiling and external turning
• TiAlN PVD coating on solid carbide substrate for extended tool life on ferrous materials
• UM chip breaker geometry for light to medium finishing cuts
• 7-degree relief angle (clearance code C) for improved clearance in close-tolerance applications
• Screw-clamp holding method for secure, repeatable insert positioning
• 2 cutting edges per insert for economical tool usage

Compatibility

This insert is part of the SANDVIK COROMANT CoroTurn 107 series and is designed for use in compatible DCET-style screw-clamp toolholders that accept a 3/8-inch inscribed circle insert with a 5/32-inch insert thickness. ISO code DCET 11 T3 04-UM 1105 can be used to cross-reference compatible toolholder specifications.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before changing inserts. Use the manufacturer-specified torque wrench and insert screw to seat the insert correctly in the pocket — do not over-tighten by hand. Inspect the toolholder pocket for wear or debris before seating the new insert to ensure proper contact and runout accuracy.
