Sandvik Coromant 5750182 Turning Insert SNMG543-MM 2025

Product Description

The SANDVIK COROMANT 5750182 is a square SNMG turning insert in the T-Max P series, manufactured from solid carbide with a CVD-applied multilayer coating of TiCN, Al2O3, and TiN. Manufacturer grade 2025 is formulated for cutting stainless steel, corresponding to ISO workpiece material code M. The insert measures 0.578 inches in length with an inscribed circle of 0.625 inches and a corner radius of 0.047 inches (3/64 inches). Neutral hand orientation, an MM chip breaker geometry, and 8 available cutting edges make this insert a productive choice for external turning operations on CNC lathes. This part is installed by machinists and CNC operators working in precision machining environments.

The 5750182 is suited for turning stainless steel on CNC lathes and turning centers in both production shop and job shop settings. The MM chip breaker geometry is designed to manage chip flow when cutting medium feeds on austenitic and other stainless alloys. The 90-degree included angle and square insert shape (ISO code S) provide structural rigidity at the cutting edge. This insert is held in the toolholder via a clamp and pin method, compatible with standard SNMG-style toolholders accepting a 0.25-inch hole diameter pin.

Key Features

• CVD multilayer coating: TiCN, Al2O3, TiN for wear resistance and thermal protection on stainless steel
• Manufacturer grade 2025 optimized for ISO M (stainless steel) primary workpiece materials
• 8 usable cutting edges per insert for extended tool life per unit
• MM chip breaker geometry for controlled chip formation at medium feed rates
• Neutral hand insert for use in standard SNMG right-hand or left-hand toolholders
• Clamp and pin holding method for secure seating and repeatable edge indexing

Compatibility

Designed as an OEM-style replacement insert for SNMG543 toolholders using clamp and pin holding; ISO designation SNMG 15 06 12-MM 2025. Accepts toolholders with a 0.25-inch (6.35 mm) bore pin diameter. Compatible toolholders must accommodate a square insert with a 0.625-inch inscribed circle and a 0.25-inch insert thickness.

Installation Notes

Installation and indexing of this insert should be performed by a qualified machinist or CNC operator with the machine in a full stop and lockout-tagout procedures followed. Inspect the toolholder pocket and clamping pin for wear or debris before seating the insert. Use the appropriate torque tool per the toolholder manufacturer's specification for the clamp screw. Do not force the insert into the pocket or use a damaged clamping pin, as this can compromise edge position and part tolerances.
