Tungaloy 6991285 Grooving Insert ETX6-040 AH725 Solid Carbide

Product Description

The TUNGALOY 6991285 is a solid carbide grooving insert in the EasyMcut series, designated ISO code ETX6-040 with manufacturer grade AH725. It carries a PVD-applied TiAlN coating for wear resistance and heat management during interrupted and continuous grooving operations. The insert has a cutting width of 0.236 inches (6.00 mm), an overall length of 0.472 inches (12.00 mm), and a corner radius of 0.016 inches (0.40 mm). It is right-hand oriented and secured by screw clamping. Licensed machinists and CNC tooling technicians install this insert in compatible EasyMcut grooving toolholders for precision external or internal grooving applications.

This insert is rated for primary use on stainless steel (ISO material code M) and steel (ISO material code P), with secondary capability on cast iron (ISO material code K). It is suited to production turning environments where consistent groove geometry and tool life on difficult-to-machine alloys are priorities. The AH725 grade combined with TiAlN PVD coating makes it a practical choice for moderate to high cutting speed operations on stainless and alloy steel components. The multi-use designation indicates suitability across varied grooving scenarios within the EasyMcut platform.

Compatibility

Designed for use with EasyMcut series grooving toolholders that accept the ETX6-040 insert style and size code 6040. Compatible workpiece materials include stainless steel, steel, and cast iron per ISO material codes M, P, and K.

Installation Notes

Installation is performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before seating or removing the insert. Use the appropriate torx or hex key to torque the clamping screw to the toolholder manufacturer specification - do not overtighten, as this can fracture the carbide insert body. Inspect the insert pocket for chips or debris before seating to ensure full contact and correct tool height.
