Sandvik Coromant 5755942 Turning Insert Vcet Coroturn 107

Product Description

The SANDVIK COROMANT 5755942 is a solid carbide turning insert in a 35-degree diamond (V) shape, designed for precision external turning operations on CNC lathes and turning centers. This insert carries a TiAlN coating applied via PVD process, which provides thermal resistance and extended tool life in steel and stainless steel applications. It features a UM chip breaker geometry suited for universal medium machining. The inscribed circle measures 0.25 inches (6.35 mm), insert length is 0.428 inches (10.87 mm), and insert thickness is 0.125 inches (3.17 mm). The corner radius is 0.20 mm (0.0079 inches). Two cutting edges are available per insert.

This insert belongs to the CoroTurn 107 series and is intended for use in screw-clamped turning toolholders that accept VCET-style inserts. Primary workpiece material is steel (ISO code P). Secondary workpiece materials include stainless steel, superalloys, and titanium (ISO codes M, S). Typical applications include finishing and semi-finishing passes on turned components in manufacturing, job shop, and production machining environments. Installation is performed by qualified machinists and CNC tooling technicians. The ISO code for this insert is VCET 11 03 02-UM 1105.

Installation Notes

Installation is performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate Torx or hex key as specified by the toolholder manufacturer when tightening the clamp screw — do not over-torque. Inspect the insert pocket and seating surfaces for chips or debris before seating a new insert to ensure proper contact and runout control.
