Tungaloy 6735305 Milling Insert LNMX0405ZER-HJ AH3135

Product Description

The TUNGALOY 6735305 is a solid carbide milling insert carrying the manufacturer designation LNMX0405ZER-HJ in grade AH3135. It is a double-sided, negative-rake, rectangular insert with four usable cutting edges. The insert measures 8.20 mm wide, 4.30 mm long, and 5.00 mm thick, with a 1.30 mm corner radius. A TiAlN coating applied via PVD process provides wear resistance and thermal stability during interrupted and continuous milling cuts. This insert is specified for use by machinists and tool-and-die professionals working with ferrous and exotic workpiece materials.

The LNMX0405ZER-HJ AH3135 insert is rated for milling steel, stainless steel, cast iron, hard materials, superalloys, and titanium, covering ISO material grades P, M, K, H, and S. The HJ chip breaker geometry and honed cutting edge style make it well suited for light-to-moderate depth-of-cut applications, with a maximum depth of cut of 1.30 mm. It is compatible with the EXLN, HXLN-M, and TXLN cutter series. Right-hand cutting orientation is standard for this insert.

Installation Notes

Insert installation and replacement should be performed by a qualified machinist with the machine spindle fully stopped and the tool safely secured in a vise or holder. Use the manufacturer-specified torque driver and screw for the LNMX insert pocket to avoid seat damage. Inspect the insert pocket seat and clamping screw for wear or debris before seating the insert. Rotate to a fresh cutting edge before replacing the insert entirely.
