Sumitomo 1PHC001 Milling Insert ACK200 Solid Carbide Lnmx

Product Description

The SUMITOMO 1PHC001 is a solid carbide milling insert designed for metal removal in milling operations on machining centers and CNC mills. It carries the ACK200 manufacturer grade and features an aluminum oxide (Al2O3) coating applied via chemical vapor deposition (CVD), which improves wear resistance and thermal stability at the cutting edge. The insert is LNMX style with a rectangular shape and measures 0.634 inches in length, 0.476 inches in width, and 0.250 inches in thickness. A corner radius of 0.032 inches helps manage edge stress during cutting. The G-style chip breaker geometry controls chip flow during interrupted or continuous cuts. This insert is sold individually and requires a minimum order of 10 pieces.

The 1PHC001 is suited for milling applications where a solid carbide substrate and CVD-coated Al2O3 finish are specified for ferrous materials, cast iron, or hardened workpieces. It fits standard LNMX insert pockets used in face milling and shoulder milling cutter bodies. Machinists and tool-room technicians working on CNC machining centers are the typical end users. The LNMX 160608 insert size designation identifies the seating and clamping geometry required for compatible toolholders.

Compatibility

Designed as a replacement-style milling insert for LNMX insert-pocket cutter bodies accepting the LNMX 160608 size designation. Confirm toolholder pocket geometry and clamping style before installation.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the spindle before seating or replacing inserts. Use the torque wrench and insert screw specified by the cutter body manufacturer — do not substitute fasteners. Inspect the insert pocket seating surface for chips or damage before installing a new insert, as debris under the insert will affect runout and tool life.
