High-performance APKT 1604 milling insert for universal applications
The APKT 1604 milling insert is a highly versatile indexable tool designed for reliable and economical milling operations in modern machining. With its sophisticated design and positive cutting geometry, it supports efficient shoulder, corner, and slot milling. Offering four different carbide grades—some featuring highly wear-resistant CVD or PVD coatings, and others specifically uncoated—this tool can be ideally adapted to the machining requirements of steel, stainless steel, aluminum, or plastics. Thus, the cutting insert opens up flexible application possibilities in industrial production.

Applications
Thanks to the wide selection of cutting materials, this indexable insert is suitable for numerous industrial machining tasks. The coated variants RT400+, RT330, and RT300 are a practical choice for general milling, roughing, and finishing in steel and stainless steel alloys. The RT100 version is particularly convincing when machining aluminum, plastics, and other non-ferrous metals, as the uncoated surface counteracts built-up edge formation. The product is perfectly matched for universal milling heads designed for APKT inserts.
Special features
The milling insert is characterized by its high adaptability and performance readiness. Various corner radii from 0.4 mm to 2.4 mm allow exact matching to the respective workpiece contour. The positive geometry contributes to a smooth cut and protects thin-walled workpieces. In addition, the robust coatings ensure a reliable tool life and reduce unplanned machine downtime in single and series production.
