Sandvik Coromant 5730657 Turning Insert Dcmx 55 Diamond

Product Description

The SANDVIK COROMANT 5730657 is a solid carbide turning insert designed for external and internal turning operations on CNC lathes and turning centers. Carrying the ISO designation DCMX 11 T3 04-WF 1125, it features a 55-degree diamond shape with a neutral hand orientation and a wiper edge geometry (WF chip breaker) that supports high surface finish and improved chip control. The insert is coated with TiAlN and AlCr2O3 applied via a PVD coating process, providing thermal resistance and wear protection. With a 3/8-inch inscribed circle and a 0.0156-inch corner radius, this insert is suited for medium to finishing passes where accuracy and edge integrity are critical. It is held in place by a screw-clamping system and is compatible with toolholders specified for the CoroTurn 107 series.

This insert is engineered primarily for cutting steel and secondarily for stainless steel workpieces, covering ISO material codes P and M respectively. It fits into the CoroTurn 107 series, which is commonly used in production turning environments where consistent chip breaking, tight tolerances, and repeatable surface finishes are required. Typical applications include shaft turning, facing, and contour operations on mid-sized components in job shops, aerospace, and general metalworking facilities. Licensed machinists and CNC operators are the primary users of this tooling. The minimum order quantity for this insert is 10 pieces per order, with a package quantity of 1 per unit.

Key Features

• 55-degree diamond insert shape (DCMX style) with neutral hand orientation
• TiAlN and AlCr2O3 dual-layer PVD coating for thermal wear resistance
• Wiper edge (WF chip breaker) geometry for improved surface finish
• Screw-clamping insert holding method for secure, repeatable seating
• 2 cutting edges per insert for cost-effective tooling use
• ISO grade 1125 carbide substrate suited for steel and stainless steel cutting

Compatibility

Designed for use with CoroTurn 107 series toolholders accepting DCMX-style inserts with a screw-clamping holding method, tolerance code M, and clearance code C. Primary workpiece material compatibility is steel (ISO code P) with secondary compatibility for stainless steel (ISO code M).

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Before changing inserts, ensure the machine spindle is fully stopped and the tool turret is in a safe, indexed position. Use the appropriate Torx or hex key to secure the clamping screw to the toolholder manufacturer's specified procedure without overtightening, which can crack the insert. Verify insert seating and shim condition before resuming cutting operations.
