Sandvik Coromant 7859293 Carbide Turning Insert

Product Description

The SANDVIK COROMANT 7859293 is a solid carbide turning insert engineered for precision metal cutting in CNC lathe and turning center applications. This insert carries a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, which delivers heat resistance and wear resistance through the cutting zone. Manufacturer grade 4415 targets steel workpieces as the primary application material. The neutral hand orientation suits a range of tool holder setups. With a corner radius of 0.0313 inches and an insert thickness of 0.4331 inches, this insert is built for consistent, repeatable performance on production turning operations. It is held in place using a clamp or screw method, compatible with standard ISO-style tooling blocks.

This insert is designed for turning operations on steel and secondary workpiece materials classified under ISO code K. The M5W chip breaker geometry controls chip flow across a variety of feed rates and depths of cut typical in general-purpose and production turning. The insert belongs to the 3-80-M5W series and is identified by ISO code 3-80-101108-8-M5W 4415. It is suited to both roughing and finishing passes on steel components in job shop, production, and OEM machining environments where tool life and surface finish consistency are priorities.

Key Features

• CVD multilayer coating: TiCN, Al2O3, and TiN for extended wear life on steel
• Manufacturer grade 4415 optimized for steel turning applications
• M5W chip breaker geometry for controlled chip evacuation across varied cutting conditions
• Neutral insert hand for versatile tool holder compatibility
• Clamp and screw holding method for secure, repeatable seating in ISO toolholders
• Corner radius of 0.0313 inches for surface finish and edge strength balance

Compatibility

Designed for use with ISO 3-80-M5W series toolholders accepting inserts with a 0.3937 inch width and 0.4331 inch thickness; confirm holder pocket specifications before installation.

Installation Notes

Insert installation and indexing should be performed by a qualified machinist or tooling technician with the spindle fully stopped and machine in a safe, locked-out state. Use the correct torque driver for screw-style clamping seats and inspect the pocket seat for chips or debris before seating the insert. Do not exceed the cutting parameters specified in the toolholder manufacturer documentation. Index or replace the insert at the first sign of flank wear, chipping, or surface finish degradation to avoid workpiece damage.
