Sandvik Coromant 5755909 Turning Insert Coroturn 107

Product Description

The SANDVIK COROMANT 5755909 is a solid carbide, uncoated turning insert designed for precision metal-cutting operations on CNC lathes and turning centers. Manufactured to ISO code VCGX 11 03 02-AL H10, this insert features a 35-degree diamond shape (V) with a 7-degree relief angle and a 0.20 mm (0.0079 inch) corner radius. The H10 uncoated carbide grade delivers sharp, consistent cutting edges suited to finishing and semi-finishing passes. With 2 cutting edges per insert and a neutral hand orientation, it is used by machinists and CNC turning specialists working to tight tolerances on non-ferrous and superalloy workpieces.

This insert is engineered primarily for non-ferrous metals such as aluminum and copper alloys, with secondary suitability for superalloys and titanium. It belongs to the CoroTurn 107 series, which is designed for external and internal turning in light to medium cutting conditions. The XM chip breaker geometry supports free-cutting action on gummy or stringy materials. Typical applications include finishing passes on aluminum components in aerospace, automotive, and general machining environments where surface finish and dimensional accuracy are critical.

Key Features

• 35-degree diamond insert shape (V) with 7-degree relief angle for low cutting forces on non-ferrous materials
• H10 uncoated solid carbide grade optimized for sharp-edge performance on aluminum and superalloys
• 0.20 mm corner radius provides a precise, controlled cutting edge for finishing operations
• XM chip breaker geometry promotes efficient chip evacuation on non-ferrous and titanium workpieces
• 2 indexable cutting edges per insert for cost-effective tooling management
• Screw-holding method (VCGX style) ensures rigid, repeatable insert seating in compatible toolholders

Compatibility

Designed for use in CoroTurn 107 series toolholders accepting VCGX 11 03 02 style inserts with screw clamping. Compatible with toolholders sized for a 1/4-inch (6.35 mm) inscribed circle insert. Suitable for external and internal turning applications on non-ferrous metals and superalloys as designated by ISO material code N and S respectively.

Installation Notes

Insert replacement and indexing should be performed by a qualified machinist with the machine powered off and the spindle locked. Use the appropriate Torx or hex key driver to secure the clamping screw to the toolholder manufacturer's recommended procedure — do not overtighten, as this can fracture carbide inserts. Inspect the insert pocket and clamping screw for wear or debris before seating a new insert. Verify runout and tool offset after indexing before resuming cutting operations.
