Sandvik Coromant 5755623 Turning Insert VBMT221-MF 1115

Product Description

The SANDVIK COROMANT 5755623 is a solid carbide turning insert designed for precision metal cutting on CNC lathes and turning centers. Manufactured to the VBMT 11 03 04-MF 1115 ISO designation, this insert features a 35-degree diamond shape with a neutral hand orientation and an MF chip breaker geometry suited for light to medium finishing cuts. The PVD-applied TiAlN and AlCr2O3 dual-layer coating delivers heat resistance and wear performance during demanding turning operations. With a 1/4-inch inscribed circle and a 1/64-inch corner radius, the insert is engineered for close-tolerance finishing work on challenging materials.

This insert is designed for turning stainless steel as its primary workpiece material, with secondary suitability for superalloys and titanium. It fits into CoroTurn 107 series toolholders that accept VBMT-style inserts held by screw clamping. Typical applications include finishing and semi-finishing passes on difficult-to-machine alloys in aerospace, medical, and industrial manufacturing environments. The insert is sold individually, with a minimum order quantity of 10 units per order.

Key Features

• 35-degree diamond insert shape (VBMT style) for low cutting forces in finishing operations
• PVD-coated TiAlN and AlCr2O3 dual-layer coating for elevated-temperature wear resistance
• MF chip breaker geometry optimized for light to medium finishing cuts on stainless steel and superalloys
• Neutral hand orientation for flexible toolholder mounting
• Screw-clamp insert holding for secure, repeatable seating in CoroTurn 107 toolholders
• Two cutting edges per insert for extended tool life between changeovers

Compatibility

Designed for use in CoroTurn 107 series toolholders accepting VBMT-style inserts with screw clamping. Primary workpiece material compatibility is stainless steel (ISO material code M), with secondary compatibility for superalloys and titanium (ISO material code S).

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine before changing inserts. Seat the insert fully against the toolholder pocket before tightening the clamping screw to the toolholder manufacturer's specified torque. Inspect the pocket and clamping components for chips or wear before installing a new insert to ensure proper seating and edge integrity.
