Sandvik Coromant 5755715 Turning Insert VBMT332-MM 2025

Product Description

The SANDVIK COROMANT 5755715 is a VBMT332-MM 2025 grade solid carbide turning insert designed for precision external turning operations. It features a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, which provides wear resistance and thermal stability during cutting. The insert has a 35-degree diamond shape, a 3/8-inch inscribed circle, and a 1/32-inch corner radius. At 0.6223 inches in length and 3/16 inches thick, it is sized for use in CoroTurn 107 toolholders. With two cutting edges and a screw-holding method, it suits high-productivity turning cycles on stainless steel and similar materials.

This insert is intended for turning applications where stainless steel is the primary workpiece material. The MM chip breaker geometry is suited for medium machining conditions, providing effective chip control across a range of feeds and depths of cut. The neutral hand orientation makes it compatible with standard right-hand and left-hand toolholder configurations within the CoroTurn 107 series. Machinists and CNC operators in production shops, tool rooms, and contract machining environments are the typical end users. It is sold individually with a minimum order quantity of 10 pieces per order.

Key Features

• CVD-coated with TiCN, Al2O3, and TiN for extended tool life on stainless steel
• 35-degree diamond insert shape (V) with a 5-degree relief angle for clearance in tight profiles
• MM chip breaker geometry optimized for medium turning on difficult-to-machine materials
• 1/32-inch (0.0313-inch) corner radius for a balance of edge strength and surface finish
• Screw-holding method with 0.1732-inch hole diameter for secure, repeatable seating
• Two usable cutting edges per insert for cost efficiency in production runs

Compatibility

Designed for use in SANDVIK COROMANT CoroTurn 107 series toolholders that accept VBMT-style inserts. ISO code VBMT 16 04 08-MM 2025 can be used to cross-reference compatible holders and pockets.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. Before changing inserts, ensure the machine spindle is stopped and all axis motion is locked out per shop safety procedures. Use the correct torx or hex key to seat the clamping screw to toolholder manufacturer torque specifications found in the toolholder documentation. Inspect the insert pocket and seating surface for chips or debris before seating the new insert to ensure accurate and repeatable tool height.
