Sandvik Coromant 5755551 Turning Insert Diamond Carbide

Product Description

The SANDVIK COROMANT 5755551 is a VBMT-style turning insert designed for precision external turning operations on CNC lathes and turning centers. Manufactured from solid carbide and coated with TiCN and TiN layers, this insert delivers wear resistance and thermal stability during finish to semi-finish cuts. The 35-degree diamond insert shape (V) provides a sharp cutting geometry suited to low-depth passes and tight-tolerance workpieces. It measures 0.4044 inches in length with a 1/4-inch inscribed circle and a 1/32-inch corner radius, making it appropriate for fine surface finish requirements in production machining environments.

This insert is used in CNC turning applications across general machining, aerospace component work, and precision part production. The VBMT geometry with UF chip breaker designation is suited for finishing operations on steel and alloy materials where chip control and surface finish quality are critical priorities. It installs via screw-clamping (insert holding method: screw) into compatible VBMT toolholders. The ISO code for this insert is VBMT 11 02 08-UF 235, which can be used to cross-reference compatible toolholder systems.

Key Features

• TiCN and TiN dual-layer coating for improved wear resistance and surface hardness
• 35-degree diamond insert shape (V) with UF chip breaker for controlled chip formation during finishing cuts
• 1/32-inch corner radius for tight-tolerance and fine-finish turning passes
• Screw-clamping retention method for secure seating and repeatable indexing
• Solid carbide substrate provides rigidity and dimensional stability under thermal load
• ISO code VBMT 11 02 08-UF 235 for straightforward toolholder cross-reference

Compatibility

This insert is compatible with VBMT-style screw-clamp turning toolholders designed for inserts with a 1/4-inch inscribed circle, B clearance code, M tolerance code, and a 2.80 mm hole diameter. Use the ISO code VBMT 11 02 08-UF 235 to verify toolholder fitment. No specific machine model or system family compatibility was stated in the product data.

Installation Notes

Installation is performed by a qualified machinist or CNC tooling technician. Power down the machine and engage the spindle lock before indexing or replacing inserts. Use the correct torx or hex key to seat the clamping screw to manufacturer specification without over-torquing. Inspect the insert pocket and seating surface for debris or damage before installing a new insert to ensure accurate positioning and prevent premature wear.
