Sandvik Coromant 5755626 Turning Insert VBMT331-PF 5015

Product Description

The SANDVIK COROMANT 5755626 is a solid carbide, uncoated turning insert in the VBMT331-PF geometry, part of the CoroTurn 107 series. This single-sided insert features a 35-degree diamond shape with a neutral hand orientation and a 5-degree relief angle. It measures 0.638 inches in length with a 3/8-inch inscribed circle and a 1/64-inch (0.0156-inch) corner radius. The PF chip breaker geometry is engineered for finishing and light cutting passes. With two cutting edges per insert, it is installed by licensed machinists and CNC operators on turning centers and lathes working in production environments.

The 5755626 is suited for turning applications on steel as its primary workpiece material, with cast iron as a secondary workpiece material. The PF chip breaker geometry performs well in finishing operations where tight tolerances and controlled chip evacuation are required. The uncoated carbide substrate in grade 5015 is matched to applications where coating would not provide a benefit or where sharp, consistent edge integrity is the priority. This insert fits screw-clamped toolholders designed for the VBMT insert style and is used on both manual lathes and CNC turning centers in job shop and production environments.

Installation Notes

Installation is performed by qualified machinists or CNC operators. Power down and lock out the machine before seating or replacing inserts. Use the correct insert screw and torque wrench per toolholder manufacturer specifications. Inspect the insert pocket and seating surface for chips or debris before clamping the new insert to ensure proper edge indexing and runout control.
