Sandvik Coromant 5755627 Turning Insert VBMT330-MF 1125

Product Description

The SANDVIK COROMANT 5755627 is a solid carbide turning insert in the VBMT style, designed for precision external turning operations on CNC lathes and turning centers. Part of the CoroTurn 107 series, it carries a dual-layer TiAlN and AlCr2O3 coating applied via PVD process, providing heat resistance and edge toughness for demanding metal removal applications. The insert features a 35-degree diamond shape (Insert Shape Code V), a 0.0079-inch corner radius, an inscribed circle of 0.375 inches, and an overall length of 0.6459 inches. It is a neutral-hand insert with 2 cutting edges and is held by screw clamping. Machinists and CNC operators working in high-production environments will find the MF chip breaker geometry well suited to finishing and semi-finishing passes.

This insert is primarily rated for steel cutting (ISO material code P) and secondarily suited for stainless steel, superalloys, and titanium (ISO codes M, P, and S). The CoroTurn 107 series targets light to medium turning applications where controlled chip formation and surface finish are priorities. Typical installation scenarios include screw-on toolholders accepting VBMT-style inserts in both facing and longitudinal turning setups on manual and CNC turning equipment. The ISO designation for this insert is VBMT 16 04 02-MF 1125.

Key Features

• MF chip breaker geometry optimized for finishing and semi-finishing passes with controlled chip evacuation
• 35-degree diamond insert shape (VBMT) allows high accessibility in tight turning profiles
• 2 usable cutting edges per insert for extended tooling value
• Screw-on holding method with clearance code B and tolerance code M for consistent seating repeatability
• Neutral hand orientation compatible with standard VBMT screw-clamp toolholders

Compatibility

Designed for use in VBMT-style screw-clamp turning toolholders within the SANDVIK COROMANT CoroTurn 107 series. ISO designation VBMT 16 04 02-MF 1125. Compatible with toolholders accepting inserts with a 0.1732-inch hole diameter and VBMT insert geometry. Verify toolholder insert pocket specifications before installation.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Always power down and lock out the machine spindle before changing inserts. Use the appropriate Torx or hex key torque screwdriver recommended by the toolholder manufacturer when seating the clamping screw — do not overtighten. Inspect the insert pocket and clamping screw for debris or wear before seating a new insert to ensure proper contact and edge alignment.
