Sandvik Coromant 5755603 Turning Insert VBMT220-PF 5015

Product Description

The SANDVIK COROMANT 5755603 is a solid carbide turning insert in the VBMT style, designed for use in external turning operations on CNC lathes and turning centers. It carries the ISO designation VBMT 11 03 02-PF 5015 and belongs to the CoroTurn 107 series. The insert features a 35-degree diamond shape, a neutral hand orientation, and a 0.20 mm (0.0079 inch) corner radius suited for precision finishing and semi-finishing passes. The uncoated bright finish of the 5015 grade makes it appropriate for applications where coating is not required or where sharp-edge geometry is critical to surface finish quality.

This insert is engineered primarily for machining steel (ISO material code P) and secondarily for cast iron (ISO material code K). It is commonly used in light to medium-duty turning operations where controlled chip formation is needed. The PF chip breaker geometry is optimized for finishing cuts, providing effective chip control at lower depths of cut and feed rates. Licensed machinists and CNC setup technicians working in job shop, production, and precision machining environments are the typical end users. The screw-in holding method ensures secure seating in compatible VBMT toolholders.

Key Features

• 35-degree diamond insert shape (shape code V) for access in tight-clearance turning profiles
• PF chip breaker geometry designed for finishing and light semi-finishing passes
• Solid carbide, uncoated (bright) 5015 grade for steel and cast iron applications
• Neutral hand orientation for flexible toolholder compatibility
• Screw-in insert holding method with 2.80 mm hole diameter for positive clamping
• Two cutting edges per insert, extending usable tool life per unit

Compatibility

Designed for use in VBMT-style toolholders compatible with the CoroTurn 107 series. Accepts inserts with a 1/4 inch inscribed circle and screw-in mounting. Verify ISO designation VBMT 11 03 02 compatibility with the toolholder before installation.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine before seating or indexing the insert. Ensure the toolholder pocket and clamping screw threads are clean and free of chips before inserting. Do not exceed the toolholder manufacturer's recommended clamping torque for the screw size used.
