Sandvik Coromant 8019708 Turning Insert Dnmg 15 04 04-XF

Product Description

The SANDVIK COROMANT 8019708 is a DNMG-series indexable turning insert designed for precision metal cutting on CNC lathes and turning centers. This insert carries the ISO designation DNMG 15 04 04-XF 4425 and is manufactured from solid carbide with a CVD-applied multilayer coating of TiCN, Al2O3, and TiN. The 55-degree diamond shape (insert shape code D) provides a strong cutting edge geometry suited for profiling and general turning. With a 0.5-inch inscribed circle and a 0.0156-inch corner radius, this insert handles finish to medium turning passes on steel workpieces. It is installed in a neutral hand orientation and is held by clamp or screw mounting. Machinists and CNC operators working in production or job-shop environments install this insert type.

This insert is rated for primary use on steel workpieces and carries a secondary workpiece material code of K, indicating suitability for cast iron in appropriate conditions. The XF chip breaker geometry is engineered for finishing operations where tight chip control and surface finish consistency are critical. It fits standard DNMG-style toolholders designed for the DNMG 431 insert size code. The 4425 manufacturer grade, combined with the CVD coating stack, delivers wear resistance and thermal stability at elevated cutting speeds typical of steel turning applications in both automotive and general machining environments.

Key Features

• CVD multilayer coating: TiCN, Al2O3, and TiN for wear resistance and thermal stability
• 55-degree diamond insert shape with neutral hand orientation
• 0.0156-inch corner radius suited for finishing and light profiling passes
• 0.5-inch inscribed circle, insert size code 431
• XF chip breaker geometry for controlled chip formation on steel
• Clamp and screw holding compatibility for secure seating in standard toolholders

Compatibility

Designed for use in standard DNMG-style indexable turning toolholders accepting the DNMG 431 insert size. Primary workpiece material is steel; secondary material code K applies. Confirm toolholder pocket specifications match the DNMG 15 04 04 geometry and clearance code N before installation.

Installation Notes

Insert replacement is performed by licensed machinists or qualified CNC operators with the machine fully stopped and energy-isolated per lockout/tagout procedures. Use the appropriate torx or hex key to remove the clamping screw or clamp before seating the new insert; do not force the insert into the pocket. Inspect the toolholder pocket for wear or debris before installing a fresh edge. Verify insert orientation and hand designation match the programmed tool path before resuming cutting operations.
