Sandvik Coromant 5755586 Turning Insert VBGT3303-UM 1125

Product Description

The SANDVIK COROMANT 5755586 is a solid carbide turning insert in the VBGT style, designed for precision external turning operations on CNC lathes and turning centers. It carries a dual-layer TiAlN and AlCr2O3 coating applied via PVD process, which provides heat resistance and edge wear performance during medium to light finishing cuts. The insert features a 35-degree diamond shape (V), a 0.1 mm corner radius, and a UM chip breaker geometry suited for versatile steel and multi-material turning. It measures 0.6498 inches in length with a 3/8-inch inscribed circle and belongs to the CoroTurn 107 series. Installation is performed by screw clamping. This insert weighs 0.24 pounds per package.

The 5755586 is suited for finishing and semi-finishing operations on steel as the primary workpiece material, with secondary capability on stainless steel, non-ferrous metals, superalloys, and titanium. The CoroTurn 107 series targets external longitudinal turning, facing, and profiling on moderate to small-diameter workpieces. The UM chip breaker geometry handles a range of depths of cut and feed rates across these material groups, making the insert a versatile choice for job shops and production turning environments running mixed material work. The ISO designation for this insert is VBGT 16 04 01-UM 1125.

Key Features

• TiAlN and AlCr2O3 dual-layer PVD coating for thermal resistance and extended edge life
• 0.1 mm corner radius for fine surface finish on finishing passes
• UM chip breaker geometry compatible with steel, stainless steel, non-ferrous metals, superalloys, and titanium
• Screw-held mounting with clearance code B and tolerance code G for repeatable positioning
• 2 cutting edges per insert for cost-effective indexing

Compatibility

Designed for use in CoroTurn 107 series toolholders that accept VBGT-style inserts with a screw clamping method. Compatible toolholders must match the VBGT insert style, 3/8-inch inscribed circle, and 0.1732-inch hole diameter. Consult the SANDVIK COROMANT CoroTurn 107 toolholder catalog for confirmed holder pairings.

Installation Notes

Turning insert replacement is performed by machining technicians or CNC setup personnel. Power down and lock out the machine spindle before indexing or replacing inserts. Use the correct Torx or hex key driver specified by the toolholder manufacturer to seat the clamping screw — do not overtighten or substitute fasteners. Inspect the toolholder pocket and seating surfaces for wear or debris before installing a new insert to ensure accurate positioning and prevent premature edge failure.
