The SANDVIK COROMANT 5724104 is a solid carbide, uncoated turning insert designed for external and internal turning operations on CNC lathes and turning centers. Belonging to the CoroTurn 107 series, this insert carries the ISO designation CCMT 09 T3 02-PF 5015 and features an 80-degree diamond shape with a neutral hand orientation. The insert measures 0.3729 inches in length with a 3/8-inch inscribed circle and a 0.20 mm (0.0079 inch) corner radius. A screw-clamp holding method and 7-degree relief angle contribute to reliable, repeatable seating in compatible toolholders. Two cutting edges are available per insert. Installed by machinists and CNC operators in precision metal-cutting environments.
This insert is intended for turning operations where steel is the primary workpiece material and cast iron is the secondary workpiece material. The PF chip breaker geometry is optimized for finishing passes, producing controlled chip evacuation and consistent surface finish on ferrous materials. The CoroTurn 107 series is commonly used in applications requiring positive-geometry inserts with a central clamping screw, typical in both production shops and job shops running steel components.
Designed for use with CoroTurn 107 series toolholders that accept CCMT 09 T3 inserts with a central clamping screw. Primary workpiece material is steel (ISO material code P); secondary workpiece material is cast iron (ISO material code K). Verify toolholder seat and clamp compatibility before installation.
Insert installation and indexing should be performed by a qualified machinist or CNC setup technician with the machine powered down and locked out per facility LOTO procedures. Use the appropriate Torx or hex key at the torque recommended by the toolholder manufacturer for the clamping screw - do not overtighten, as this can fracture the insert or damage the seat. Inspect the toolholder pocket and clamp for chips or debris before seating the new insert. Always verify runout and tool offset after indexing before returning the machine to production.
