Sandvik Coromant 5734917 Turning Insert Coroturn 111

Product Description

The SANDVIK COROMANT 5734917 is a solid carbide turning insert in the DPMT style, designed for precision external turning operations on CNC lathes and turning centers. It carries an ISO designation of DPMT 07 02 02-MF 1125, featuring a 55-degree diamond insert shape with an 11-degree relief angle and the MF chip breaker geometry. The 1125 grade substrate is PVD-coated with TiAlN and AlCr2O3 for enhanced wear resistance and thermal stability at the cutting edge. With a 1/4-inch inscribed circle, a 0.2 mm corner radius, and neutral hand orientation, this insert suits finishing and semi-finishing cuts on a variety of metallic workpieces. Installation is performed by licensed machinists and CNC operators.

This insert is primarily suited for turning steel workpieces and is also rated for use on stainless steel, superalloys, and titanium. The MF chip breaker geometry is optimized for medium to light finishing passes where controlled chip formation and surface finish are critical. It is held in the toolholder via a screw clamping method and fits standard DPMT-style pockets. The CoroTurn 111 series is engineered for small-part turning and close-tolerance applications where insert stability and edge precision are essential.

Key Features

• PVD-applied TiAlN and AlCr2O3 dual-layer coating for thermal resistance and long tool life
• 55-degree diamond insert shape with 11-degree relief angle for clearance and edge access
• MF chip breaker geometry optimized for finishing cuts on steel and difficult-to-machine alloys
• Neutral hand orientation for versatile toolholder compatibility
• Screw-held mounting method provides repeatable insert positioning
• Two cutting edges per insert for cost-effective edge utilization

Compatibility

Designed for use in DPMT-style screw-clamp toolholders compatible with the SANDVIK COROMANT CoroTurn 111 series. Rated for primary use on steel (ISO material code P) and secondary use on stainless steel, superalloys, and titanium (ISO material codes M, P, and S).

Installation Notes

Insert replacement should be performed by a qualified machinist with the machine spindle stopped and all motion fully arrested per shop lockout/tagout procedures. Use the correct Torx or hex key specified for the toolholder seat screw and do not overtighten, as this can crack the carbide substrate. Inspect the insert pocket seating surface for chips or contamination before seating the insert. Verify insert orientation and hand before resuming cutting operations.
