Tungaloy 6818305 Milling Insert ASMT11T304PDPR-MJ AH120

Product Description

The TUNGALOY 6818305 is a solid carbide milling insert carrying the manufacturer part designation ASMT11T304PDPR-MJ in the AH120 grade. This single-sided, right-hand parallelogram insert features a TiAlN coating applied via PVD process, delivering wear resistance across a wide range of cutting conditions. It is sized at insert code 11T304, with a thickness of 0.146 inches, an inscribed circle of 0.264 inches, and a length of 0.484 inches. With a positive rake geometry, honed cutting edge, and MJ chip breaker, this insert is engineered for productive milling in steel, stainless steel, cast iron, hard materials, and superalloys and titanium. Licensed trades machinists and tool-room professionals are the primary installers.

This insert is suited for milling applications in both production and job-shop environments where the workpiece materials span ISO material groups P, M, K, H, and S. The ASMT series geometry supports a maximum depth of cut of 0.417 inches (10.60 mm), making it applicable to medium-depth face and shoulder milling passes. The MJ chip breaker targets reliable chip control across variable feed and speed conditions common in these material groups.

Key Features

Installation Notes

Installation is performed by qualified machinists or tool-room technicians. De-energize the machine and lock out the spindle before handling or seating inserts. Use the correct torx or hex driver to the tool manufacturer's specified seating procedure for screw-held inserts; avoid over-torquing the clamping screw. Inspect the insert pocket and seating surfaces for chips or debris before installing a new insert.
