Sandvik Coromant 5723730 Turning Insert CCMT433-MR 2035

Product Description

The SANDVIK COROMANT 5723730 is a solid carbide turning insert in the CCMT433-MR 2035 designation, designed for precision external turning operations on CNC lathes. It carries an 80-degree diamond shape (insert shape code C) with a 3/64-inch (0.0469-inch) corner radius and a 1/2-inch inscribed circle. The grade 2035 substrate features a PVD coating process and an MR chip breaker geometry with a rounded cutting edge style. The T-style chip breaker aids in controlling chip flow during medium to finishing-range cuts. Relief angle is 7 degrees. This insert is part of the CoroTurn 107 series and is held in place by a screw clamping method. Machinists and CNC programmers specify this insert for controlled-chip turning applications across a range of workpiece materials.

The 5723730 is suited for external turning on CNC turning centers in production and job-shop environments, both light-duty and general finishing applications. The CCMT insert style with screw-on holding is a standard configuration compatible with ISO-designated CCMT toolholders. Maximum depth of cut reaches 11.70 mm. The ISO code for this insert is CCMT 12 04 12-MR 2035. It is commonly specified where consistent surface finish and tool-life predictability matter, such as in aerospace, automotive, and general machining applications using carbide-compatible toolholder systems.

Key Features

• 80-degree diamond insert shape (code C) for stable, two-edge cutting geometry
• Grade 2035 solid carbide with PVD coating process for wear resistance
• 3/64-inch (0.0469-inch) corner radius for controlled finish on external turning passes
• MR chip breaker geometry with rounded cutting edge for effective chip control
• 1/2-inch inscribed circle (12.70 mm) with 3/16-inch insert thickness
• Screw-on holding method (clearance code C, tolerance code M) for secure tool seating

Compatibility

Designed for use in CCMT-style screw-clamp turning toolholders compatible with the CoroTurn 107 series. ISO code CCMT 12 04 12-MR 2035 should be used to confirm toolholder compatibility. Verify insert pocket dimensions against holder specifications before installation.

Installation Notes

This insert is installed by a machinist or toolroom technician into a compatible CCMT screw-clamp toolholder. Before changing inserts, ensure the lathe is powered down and the spindle is fully stopped. Use the appropriate Torx or hex key to secure the clamp screw to the toolholder manufacturer's specification. Inspect the insert pocket and seating surface for chips or debris before seating the new insert, as contamination can affect cutting geometry and tool life.
