Sandvik Coromant 5730741 Turning Insert Dcmt H13A Carbide

Product Description

The SANDVIK COROMANT 5730741 is a solid carbide turning insert designed for precision external turning operations. It features a 55-degree diamond (D) insert shape with a DCMT style designation and a neutral hand orientation. The insert carries the H13A uncoated, bright carbide grade and a KM chip breaker geometry. With an inscribed circle of 0.375 inches and a corner radius of 0.031 inches, it is engineered for controlled chip formation and consistent surface finish in light to medium turning applications. Licensed machinists and CNC turning specialists install this insert in compatible CoroTurn 107 toolholders as part of routine cutting tool changeovers.

This insert is part of the SANDVIK COROMANT CoroTurn 107 series and is optimized for machining cast iron (ISO material group K) as its primary workpiece material, with non-ferrous metals (ISO group N) as a secondary application. It is suited for both roughing and finishing passes where an uncoated carbide grade performs reliably without the thermal barrier of a coating. Typical use cases include CNC lathe operations in job shop and production environments where close tolerances and repeatable tool life are required.

Key Features

• DCMT insert style with 55-degree diamond shape and neutral hand orientation
• H13A uncoated solid carbide grade — bright finish, no coating delamination risk
• KM chip breaker geometry for controlled chip evacuation in cast iron and non-ferrous turning
• Screw-lock insert holding method for positive, repeatable seating in the toolholder pocket
• Two cutting edges per insert for extended usable tool life before discard
• ISO designation DCMT 11 T3 08-KM H13A for cross-reference with toolholder and catalog specifications

Compatibility

Designed for use in CoroTurn 107 series toolholders. ISO insert designation DCMT 11 T3 08-KM H13A can be used for cross-referencing compatible clamping units and toolholder bodies within this series.

Installation Notes

Installation is performed by qualified machinists or CNC tool-setup technicians. Before changing inserts, confirm the machine spindle is locked and the turret is indexed to a safe position. Use the correct torx or hex key torque tool as specified by the toolholder manufacturer when tightening the clamping screw — do not overtighten or use impact tools on insert screws. Inspect the toolholder pocket and screw for wear or damage before seating the new insert.
