Sandvik Coromant 7860947 Turning Insert Cvd Carbide

Product Description

The SANDVIK COROMANT 7860947 is a solid carbide turning insert engineered for precision metal-cutting operations on steel workpieces. This insert carries ISO code 3-80-101112-8-M5 and belongs to the 3-80-M5 series. It features a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, which provides wear resistance and heat management during continuous and interrupted turning. The M5 chip breaker geometry controls chip flow across a range of cutting depths and feed rates. With a 0.0469 inch corner radius and a neutral hand orientation, this insert suits a broad range of turning applications where edge sharpness and coating integrity are critical. Licensed machinists and CNC operators install this insert in compatible tool holders on production turning centers.

This insert is designed for turning steel workpieces, classified under primary workpiece material Steel and secondary material code K. It fits turning operations on CNC lathes and manual engine lathes where ISO-style indexable inserts are used. The neutral hand designation means it can be positioned for both left- and right-hand turning passes depending on the tool holder configuration. The M5 chip breaker is suited to medium-feed turning where chip control and surface finish are both process priorities. The 3-80-M5 series designation identifies the insert geometry family and ensures compatibility with matched Sandvik Coromant tool holders of the same series.

Key Features

• CVD multilayer coating: TiCN, Al2O3, and TiN for wear resistance and thermal stability
• Solid carbide grade 4425 optimized for steel turning applications
• M5 chip breaker geometry for controlled chip evacuation at medium feed rates
• Neutral hand orientation for flexible left- or right-hand tooling setups
• 0.0469 inch corner radius for a balance of edge strength and surface finish
• Clamp and screw holding method compatible with standard ISO indexable tool holders

Compatibility

Designed for use with SANDVIK COROMANT 3-80-M5 series tool holders that accept ISO indexable turning inserts with the 3-80-101112-8-M5 geometry designation. Verify holder pocket dimensions and clamping method against the series specification before installation.

Installation Notes

Installation of indexable turning inserts should be performed by a qualified machinist with the machine spindle fully stopped and the machine locked out per OSHA lockout/tagout procedures. Use the appropriate torx or hex key to seat the insert clamp or screw to the tool holder manufacturer specification. Inspect the insert pocket for debris or wear before seating a new insert, as a contaminated pocket will affect cutting geometry. Never exceed the cutting parameter limits established by the tool holder and insert series documentation.
