Tungaloy 6849641 Milling Insert AH120 Solid Carbide

Product Description

The TUNGALOY 6849641 is a solid carbide milling insert in the XCET series, designed for high-performance face and shoulder milling operations. It carries the AH120 manufacturer grade with a TiAlN PVD coating, delivering wear resistance and thermal stability across a broad range of cutting applications. The insert features a parallelogram shape with a positive rake geometry, a 45-degree included angle, and a honed cutting edge style. Two cutting edges are available per insert, and the right-hand orientation suits standard ECC31 cutter body configurations. Licensed machinists and CNC setup technicians are the primary installers of this insert.

This insert is suited for milling steel, stainless steel, cast iron, hard materials, and superalloys including titanium. It fits into the ECC31 cutter series and is identified by ANSI and ISO code XCET310404ER AH120. The positive rake and honed edge preparation make it appropriate for both roughing and finishing passes where chip control and surface finish consistency are priorities. Applications span general machining shops, aerospace component work, and heavy manufacturing environments where multiple workpiece material types are encountered on a single machine.

Key Features

• AH120 grade with TiAlN PVD coating for wear resistance across steel, stainless, cast iron, and titanium
• Parallelogram insert shape with 45-degree included angle and positive rake for efficient chip evacuation
• Honed cutting edge style reduces micro-chipping during interrupted cuts
• Two usable cutting edges per insert maximizes tooling economy
• Right-hand orientation compatible with ECC31 cutter body series
• Screw-holding method ensures rigid, repeatable seating in the pocket

Compatibility

Designed for use with the ECC31 cutter series. ANSI and ISO designation XCET310404ER AH120 confirms direct fitment to pockets specified for the XCET310404ER insert form factor.

Installation Notes

Insert seating and torque procedures should follow the cutter body manufacturer specifications for the ECC31 series. Power down and lock out the spindle before indexing or replacing inserts. Use the correct Torx or hex key supplied with the cutter body to seat the clamping screw without overtightening, which can crack the carbide substrate. Inspect the insert pocket for chips or debris before seating a new insert.
