Sandvik Coromant 5755939 Turning Insert Coroturn 107

Product Description

The SANDVIK COROMANT 5755939 is a solid carbide, uncoated turning insert designed for precision machining of non-ferrous metals, superalloys, and titanium. It carries the ISO designation VCGX 11 02 02-AL H10 and belongs to the CoroTurn 107 series. The insert features a 35-degree diamond shape (VCGX style), a 0.2 mm corner radius, and a neutral hand orientation. With an inscribed circle of 0.25 inches and an insert length of 0.428 inches, it is sized for light to medium finishing operations. The H10 carbide grade and bright, uncoated surface make it well suited for cutting materials where coating adhesion or heat buildup is a concern. Machinists and CNC operators working on aluminum, copper, and similar non-ferrous stock will find this insert a direct fit for compatible CoroTurn 107 toolholders.

This insert is intended for turning applications on CNC lathes and turning centers where tight tolerances and fine surface finishes are required. Its primary workpiece material is non-ferrous metal, with secondary applications in superalloys and titanium. The screw-in holding method and VCGX geometry suit both external and internal turning setups. The MMC chip breaker geometry supports chip control during finishing passes at higher surface speeds typical for aluminum and light alloy work. This insert is sold individually with a minimum order quantity of 10 units.

Installation Notes

Insert installation and indexing should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before changing inserts. Use the correct Torx or hex key as specified by the toolholder manufacturer for the clamping screw - do not overtighten. Inspect the toolholder pocket and seating surface for chips or damage before seating a new insert.
