Sandvik Coromant 5724274 Turning Insert Ccmt Coroturn 107

Product Description

The SANDVIK COROMANT 5724274 is a CCMT-style turning insert from the CoroTurn 107 series, designed for precision external turning operations on CNC lathes and turning centers. This solid carbide insert carries a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, which builds heat resistance and wear life across a range of cutting conditions. The 80-degree diamond insert shape (Shape Code C) provides a strong cutting edge, while the MF chip breaker geometry is engineered for light-to-medium finishing cuts. The insert features a neutral hand orientation and is held in place by a screw-clamp method.

This insert is intended primarily for machining stainless steel (ISO material code M), making it well-suited for shops running 300-series and 400-series stainless components. Typical applications include finish turning of shafts, flanges, and fittings in industrial manufacturing environments. The MF chip breaker promotes controlled chip formation at lower feed rates, which is critical for achieving tight surface finish tolerances on difficult-to-machine alloys. Installation is performed by licensed machinists and tooling setup professionals in production and job-shop settings.

Key Features

• CVD multilayer coating: TiCN, Al2O3, and TiN for extended tool life on stainless steel
• MF chip breaker geometry suited for light-to-medium finishing passes
• 80-degree diamond insert shape (CCMT) for strong edge geometry
• Screw-clamp insert holding for secure, repeatable seating in compatible toolholders
• Neutral hand orientation for flexible toolholder compatibility
• Two cutting edges per insert

Compatibility

Designed as an OEM-spec insert for SANDVIK COROMANT CoroTurn 107 series toolholders accepting CCMT-style inserts with a 3/8-inch inscribed circle. ISO designation: CCMT 09 T3 08-MF 2025.

Installation Notes

Insert replacement should be performed by a qualified machinist with the machine fully powered down and the spindle locked. Use the appropriate Torx or hex key to the toolholder manufacturer's specified torque procedure when seating the screw clamp. Inspect the insert pocket for chips or debris before seating the new insert to ensure full, flat contact. Always index or replace the insert before edge failure to avoid workpiece damage or toolholder wear.
