Sandvik Coromant 5752110 Turning Insert TCGT220-UM 1115

Product Description

The SANDVIK COROMANT 5752110 is a solid carbide turning insert in the CoroTurn 107 series, designed for precision external turning operations on CNC lathes and turning centers. The insert carries a TCGT220-UM 1115 designation, identifying it as a 60-degree triangular geometry with a UM chip breaker and 1115 grade substrate. The 1115 grade features a TiAlN and AlCr2O3 PVD coating optimized for cutting stainless steel, superalloys, and titanium. With a 0.25-inch inscribed circle diameter and a 0.0079-inch (0.20 mm) corner radius, this insert delivers fine finishing and semi-finishing performance. Each insert provides three usable cutting edges and is held by screw clamping.

This insert is suited for light to medium turning passes on stainless steel (ISO material code M), superalloys, and titanium (ISO material code S) in both production and job-shop environments. The UM chip breaker geometry is engineered for the stringy, work-hardening chips common when machining these difficult materials. Typical applications include shaft turning, bore finishing on chucked components, and facing operations where close tolerances and good surface finish are required. The CoroTurn 107 series is a common choice for positive-rake toolholders used in lower-cutting-force applications on modern CNC turning equipment.

Key Features

• TiAlN and AlCr2O3 PVD coating for heat resistance and extended tool life on stainless and superalloy workpieces
• UM chip breaker geometry controls chips effectively on work-hardening materials
• Three cutting edges per insert maximize value per unit consumed
• 0.20 mm corner radius suits fine to medium finishing passes
• Screw-clamp holding method provides rigid, repeatable insert seating
• ISO code TCGT 11 03 02-UM 1115 for cross-reference with toolholder documentation

Compatibility

Designed for use in CoroTurn 107 series positive-rake screw-clamp toolholders that accept TCGT-style triangular inserts with a 0.25-inch inscribed circle. Consult the toolholder manufacturer documentation to confirm pocket geometry and clamping pin diameter before installation.

Installation Notes

Installation is performed by machining technicians using the appropriate Torx or hex key for the clamp screw specified by the toolholder manufacturer. Power down and lock out the machine spindle before changing inserts. Ensure the insert seat and pocket are clean and free of chips or debris before seating the new insert, as contamination under the insert will affect runout and edge life. Follow the toolholder manufacturer torque specification for the clamping screw — do not overtighten.
