Sandvik Coromant 5755664 Turning Insert VBMT331-UR H13A

Product Description

The SANDVIK COROMANT 5755664 is a solid carbide turning insert designed for precision metal cutting operations on CNC lathes and turning centers. Manufactured to the VBMT insert style with a 35-degree diamond shape, this uncoated (bright finish) insert carries the H13A grade designation, indicating a fine-grain carbide substrate suited for finishing and semi-finishing cuts. The insert measures 0.638 inches in length with a 3/8-inch inscribed circle and a 1/64-inch corner radius. The UR chip breaker geometry supports controlled chip formation during turning. Licensed machinists and CNC operators install this insert type in compatible toolholders as a direct replacement during scheduled tooling changes.

This insert is used in turning applications on ferrous and non-ferrous workpieces where a sharp, uncoated carbide edge is preferred over coated alternatives. Typical scenarios include finishing passes on cast iron, hardened steel, and non-metallic materials where coating adhesion or edge build-up is a concern. The ISO code VBMT 16 04 04-UR H13A provides direct cross-reference for sourcing and toolholder matching. The screw-type insert holding method (clearance code B, tolerance code M) is standard for indexable toolholder systems used in production and job-shop turning environments.

Key Features

• VBMT insert style with 35-degree diamond shape (insert shape code V) for pointed-tip geometry
• H13A uncoated solid carbide grade — bright finish, no coating layer
• 1/64-inch (0.0156-inch) corner radius for fine detail and finishing work
• UR chip breaker geometry for predictable chip control during turning
• Screw-type insert holding method compatible with standard VBMT indexable toolholders
• ISO code VBMT 16 04 04-UR H13A for direct cross-reference and toolholder matching

Compatibility

Designed for use in indexable turning toolholders that accept VBMT-style inserts with screw-type clamping. ISO code VBMT 16 04 04-UR H13A provides the reference for confirming toolholder compatibility. Minimum order quantity is 10 pieces; individual package quantity is 1.

Installation Notes

Installation is performed by CNC machinists or tool-room technicians during scheduled insert indexing or replacement. Power down and lock out the machine spindle before removing or seating the insert. Use the appropriate Torx or hex key to secure the clamping screw to the toolholder manufacturer's specified procedure — do not overtighten, as carbide inserts are brittle. Inspect the toolholder pocket and seating surface for chips or wear before installing a new insert.
