Sandvik Coromant 5730956 Turning Insert DCMT32.51-MF 1115

Product Description

The SANDVIK COROMANT 5730956 is a solid carbide turning insert in the CoroTurn 107 series, designed for precision external turning operations on CNC and manual lathes. Carrying the ISO designation DCMT 11 T3 04-MF 1115, this insert features a 55-degree diamond shape with a neutral hand orientation and a 7-degree relief angle. The dual-layer TiAlN and AlCr2O3 coating is applied via PVD process, delivering high heat resistance and edge integrity at elevated cutting speeds. It is intended for use by machinists and tooling specialists working in production and job-shop environments.

This insert is optimized for machining stainless steel as its primary workpiece material, with secondary suitability for superalloys and titanium. The MF chip breaker geometry is engineered for finishing and semi-finishing cuts where tight tolerances and superior surface finish are required. The screw-type holding method provides secure clamping in DCMT-compatible toolholders. It is well suited for aerospace, medical, and industrial component machining where difficult-to-cut materials are common.

Key Features

• PVD-coated with TiAlN and AlCr2O3 for high-temperature wear resistance
• MF chip breaker geometry designed for finishing cuts on stainless steel and superalloys
• 55-degree diamond insert shape with 7-degree relief angle for clearance in tight contours
• Screw-type insert holding for repeatable, rigid positioning in compatible toolholders
• Neutral hand orientation for flexible toolholder compatibility
• 2 cutting edges per insert to maximize value per piece

Compatibility

Designed for use in DCMT-style toolholders compatible with the CoroTurn 107 series. Primary workpiece material is stainless steel (ISO material code M); secondary materials include superalloys and titanium (ISO material code S). Insert size code 32.51 with ISO designation DCMT 11 T3 04-MF 1115.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and the toolholder is clean and free of chips before seating the insert. Use the appropriate torx or hex key to torque the clamping screw per the toolholder manufacturer specifications. Inspect the insert seat and clamping screw condition before each insert change to prevent premature edge failure or insert movement during cutting.
