Sandvik Coromant 5733331 Turning Insert MABR3020 1025

Product Description

The SANDVIK COROMANT 5733331 is a solid carbide turning insert in the MABR style, designed for precision grooving and parting operations on CNC lathes and turning centers. It carries a dual PVD coating of TiAlN and TiN, which provides thermal resistance and wear protection during high-speed cutting. The insert features a full radius geometry with a 0.20 mm corner radius and a right-hand cutting orientation. With an inscribed circle of 0.125 inches and an insert thickness of 0.125 inches, this is a compact, small-bore insert suited to tight-clearance applications. It is installed by licensed machinists and CNC operators working in production turning environments.

This insert belongs to the SANDVIK COROMANT CoroCut XS series, which targets small-part turning and grooving where radial and axial space is limited. Typical applications include grooving shallow profiles, facing small-diameter workpieces, and turning operations on Swiss-type and gang-tool lathes. The right-hand configuration suits standard tool orientations common in production-volume shops. The MABR insert style and grade 1025 substrate make it appropriate for a range of workpiece materials where PVD-coated carbide performs reliably. It is sold individually but requires a minimum order of 5 pieces.

Key Features

• Solid carbide substrate with PVD-applied TiAlN and TiN dual coating for wear and heat resistance
• Full radius geometry with 0.20 mm (0.0079 inch) corner radius for consistent profile accuracy
• MABR insert style with irregular shape code M and right-hand cutting orientation
• Inscribed circle of 0.125 inches (3.17 mm) for compact small-bore and small-part applications
• Screw-holding method for secure, repeatable seating in compatible toolholders
• Multi-use insert rated for turning applications per ISO code MABR 3 020 1025

Compatibility

Designed for use in SANDVIK COROMANT CoroCut XS series toolholders that accept the MABR 3020 insert seat. Confirm toolholder seat geometry and insert size code 3020 before installation. Do not substitute into holders rated for different insert styles or seat sizes.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before changing inserts. Use the appropriate Torx or hex key driver to seat the clamping screw to the toolholder manufacturer specification — do not overtighten, as carbide inserts are brittle and can fracture under excessive clamp force. Inspect the insert seat and clamp mechanism for debris or damage before seating the new insert.
