Sandvik Coromant 7960648 RCMT1204 MP-H7 4425 Turning Insert

Product Description

The SANDVIK COROMANT 7960648 is a round turning insert from the CoroTurn 107 series, designed for single-point turning operations on CNC lathes and turning centers. It carries manufacturer grade 4425 and features a CVD-applied multilayer coating of TiCN, Al2O3, and TiN for wear resistance and thermal protection during cutting. The insert has a 12 mm inscribed circle, a 4.76 mm thickness, and a neutral hand orientation. It is suited for machining cast iron (ISO K) as a primary application and steel (ISO P) as a secondary application. This insert is installed by machinists and CNC tooling technicians in production and job-shop environments.

The 7960648 fits CoroTurn 107 toolholders that accept RCMT-style round inserts with a clamp and screw holding method. Its round shape and C clearance angle make it a versatile choice for profiling, contour turning, and copy turning where a full 360-degree cutting edge is beneficial. It is appropriate for both finishing and semi-finishing passes on cast iron and steel workpieces. The neutral hand designation means it can be used in both right-hand and left-hand cutting directions depending on holder orientation.

Key Features

• CVD multilayer coating — TiCN, Al2O3, TiN — provides heat and abrasion resistance
• Round insert shape (RCMT) delivers a full 360-degree usable cutting edge
• 12 mm inscribed circle with 4.76 mm insert thickness for rigid, stable seating
• Neutral hand orientation compatible with right-hand and left-hand toolholders

Compatibility

Designed for use with SANDVIK COROMANT CoroTurn 107 toolholders accepting RCMT 12 04 style round inserts. ISO code RCMT 12 04 MP-H7 4425 identifies the full insert designation for toolholder and catalog cross-reference.

Installation Notes

Insert replacement should be performed with the machine in a locked-out, de-energized state per applicable lockout/tagout procedures. Use the correct Torx or hex key to the toolholder manufacturer's specified procedure when seating the clamping screw — do not overtighten. Inspect the insert pocket seat for chips or contamination before seating the new insert. Dispose of worn carbide inserts in accordance with local regulations for carbide and heavy-metal materials.
