Sandvik Coromant 6075408 Turning Insert VCGX331AL 1105

Product Description

The SANDVIK COROMANT 6075408 is a solid carbide turning insert in the CoroTurn 107 series, designed for precision external turning operations. This insert carries a VCGX331AL geometry with a TiAlN2 PVD coating and a 35-degree diamond shape, making it well-suited for finishing and semi-finishing cuts on difficult materials. It measures 16.61 mm (0.6539 inches) in length with a 3/8-inch inscribed circle and a 1/64-inch (0.40 mm) corner radius. The AL chip breaker geometry is engineered to handle the demanding chip control requirements common when machining stainless steel and superalloys. Installation is performed by licensed machinists and CNC operators in production and job shop environments.

This insert is intended for use in turning centers and CNC lathes running external turning applications on stainless steel (ISO material group M) as the primary workpiece material. Secondary applications include superalloys and titanium (ISO material group S). The neutral hand orientation allows use in standard right-hand toolholders compatible with VCGX-style seating. The screw-on insert holding method provides secure clamping and repeatable edge indexing. Maximum depth of cut reaches 16.21 mm (0.6382 inches), supporting both light finishing passes and moderate material removal rates on challenging alloys.

Key Features

• TiAlN2 PVD coating for enhanced heat resistance and tool life on stainless steel and superalloys
• 35-degree diamond insert shape (VCGX style) for access in tight profiling and contour turning
• AL chip breaker geometry optimized for stainless steel and titanium finishing cuts
• 1/64-inch (0.40 mm) corner radius for tight-tolerance surface finish requirements
• Screw-on holding method ensures positive seating and repeatable indexing
• Two cutting edges per insert for extended tooling value

Compatibility

Designed for use with CoroTurn 107 series toolholders accepting VCGX 16 04 04 insert style. Compatible with screw-on insert seating pockets with a 4.40 mm (0.1732-inch) hole diameter. ISO code: VCGX 16 04 04-AL 1105. Suitable for turning centers and CNC lathes running stainless steel (ISO group M), superalloy, and titanium (ISO group S) workpieces.

Installation Notes

Insert installation and indexing should be performed by a qualified machinist or CNC operator with the spindle powered down and the machine in an e-stop or lockout/tagout state per facility safety protocols. Use the appropriate Torx or hex key specified by the toolholder manufacturer to tighten the clamping screw — do not use impact tools on insert screws. Inspect the insert pocket seat and clamping screw threads for chips or damage before seating a new insert. Discard inserts when cutting edges show visible wear, chipping, or built-up edge rather than attempting to re-use a degraded edge.
