Sandvik Coromant 5915145 VNMG332-SM H13A Turning Insert

Product Description

The SANDVIK COROMANT 5915145 is a solid carbide, uncoated turning insert in the VNMG332-SM H13A designation, part of the T-Max P series. It features a 35-degree diamond insert shape (V-code), a 3/8 inch inscribed circle, and a 1/32 inch corner radius. The SM chip breaker geometry is engineered for controlled chip formation during turning operations on difficult-to-machine materials. With four cutting edges and a neutral hand orientation, this insert suits high-precision external turning applications where edge integrity and dimensional consistency are critical. Licensed machinists and CNC lathe operators working in aerospace, medical, and energy sectors will find this insert well-suited to demanding production runs.

This insert is intended for turning stainless steel as its primary workpiece material (ISO material code M), with secondary suitability for superalloys and titanium (ISO material code S). The T-Max P series targets productive turning across a range of work materials where toughness and thermal stability are required. The H13A uncoated carbide grade performs best in finishing and semi-finishing passes where sharp edge retention and low built-up edge tendency are priorities. Maximum depth of cut is 2.40 mm (0.0945 inches). The ISO designation for this insert is VNMG160408SMH13A.

Key Features

• VNMG insert style with 35-degree diamond shape and neutral hand orientation
• H13A uncoated solid carbide grade engineered for stainless steel, superalloys, and titanium
• SM chip breaker geometry for controlled chip formation in difficult materials
• Four usable cutting edges for extended tool economy per insert
• Clamp and pin insert holding method for secure seating under cutting loads
• 3/8 inch inscribed circle with 1/32 inch corner radius for precise finishing geometry

Compatibility

Designed for use in toolholders accepting VNMG-style inserts with a 3/8 inch inscribed circle. Compatible with T-Max P series tooling systems. Verify toolholder pocket specifications and clamping style before installation. Confirm ISO code VNMG160408SMH13A matches the toolholder designation on file.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician with the machine powered down and all axes at rest before insert indexing or replacement. Use the appropriate torx or hex key specified by the toolholder manufacturer when tightening the clamp screw — do not overtighten. Inspect the insert pocket and seating surfaces for chips, debris, or wear before seating a new insert. Confirm insert orientation and hand designation match the toolholder before resuming operation.
