Sumitomo 14HA920 Milling Insert SOMT120408PDERH ACP200

Product Description

The SUMITOMO 14HA920 is a solid carbide coated milling insert in the SOMT style, designed for high-performance face and shoulder milling operations. Manufactured to the ACP200 grade with a PVD coating process, this insert delivers wear resistance and edge stability across demanding cutting applications. The square insert shape measures 0.5000 inches in length and width with a thickness of 0.1874 inches, and features a corner radius of 0.0315 inches (0.80 mm). It is sized to the 1204 insert size code and conforms to ISO standards. Licensed HVAC technicians do not install these — this part is specified and installed by machining professionals and CNC tooling technicians.

The 14HA920 is suited for milling stainless steel and steel workpieces in both roughing and semi-finishing operations. The H chip breaker geometry is optimized to manage chip flow and reduce cutting forces in ferrous and stainless steel materials, covering ISO material codes M and P. This insert is applicable in commercial and industrial machining environments where consistent tool life and surface finish are critical. It is sold individually with a minimum order quantity of 10 units.

Installation Notes

Insert seating and torque should be performed by qualified machining technicians following the toolholder manufacturer specifications. Power down and lock out the machine spindle before changing inserts. Inspect the insert pocket and clamping screw for wear or debris before seating a new insert. Do not exceed the toolholder rated speed or depth-of-cut parameters for this insert size.
