Sandvik Coromant 5724261 Turning Insert Ccmt Coroturn 107

Product Description

The SANDVIK COROMANT 5724261 is a CCMT-style turning insert designed for external turning operations on CNC lathes and turning centers. It carries the ISO designation CCMT09T308MF1105 and belongs to the CoroTurn 107 series. The insert is manufactured from solid carbide and finished with a TiAlN2 coating applied via PVD process, which enhances wear resistance and thermal stability at the cutting edge. The 80-degree diamond shape (insert shape code C) provides two usable cutting edges per insert. Key geometry specs include a 0.80 mm (1/32 inch) corner radius and an MF chip breaker designed for finishing cuts at light to moderate depths.

This insert is suited for finish and semi-finish turning of steel and stainless steel workpieces, corresponding to ISO material groups P and M. Typical applications include shaft turning, facing, and contour turning where consistent surface finish and tight dimensional control are required. The MF chip breaker geometry is optimized for low feed rates and shallow depths of cut, making this insert a common choice when machining close-tolerance diameters or transitioning between shoulders and tapers on precision turned components.

Key Features

• CCMT insert style with 80-degree diamond shape and 7-degree relief angle for positive cutting geometry
• TiAlN2 PVD coating on solid carbide substrate for extended tool life in steel and stainless steel
• MF chip breaker geometry optimized for finishing and light semi-finishing cuts
• 0.80 mm corner radius balances edge strength with surface finish quality
• Screw-clamping insert holding method for repeatable seating in compatible toolholders
• Two cutting edges per insert for cost-effective indexing

Compatibility

Designed for use in CoroTurn 107 series toolholders accepting CCMT-style inserts with a 3/8 inch (0.3750 inch) inscribed circle. Primary workpiece material is steel (ISO group P); secondary workpiece material is stainless steel (ISO group M).

Installation Notes

Insert replacement and indexing should be performed by a qualified machinist or CNC tooling technician with the machine in a full stop and all axes at rest. Power down the machine and engage the spindle lock before accessing the toolholder. Use the appropriate Torx or hex key to release the clamping screw, seat the new insert fully against the pocket locating surfaces, and torque the screw to the toolholder manufacturer specification. Inspect the cutting edge and chip breaker for damage before resuming cuts.
