Dapra Corporation’s 12-mm cutter bodies and inserts to its line of 90-degree square shoulder precision mills. Machined from double-hardened tool steel to minimize runout and maximize strength, these cutters are designed with a fine pitch for faster feed rates and a smoother cutting action that generates less noise and pressure. This particular precision cutter and insert combination provides longer tool life and improved productivity, especially on lighter-duty machines. End mills are available in cutting diameters from 0.625” to 1.500”. Shell mills, with varying pitch options, cut from 1.5” to 4”. Helical roughing end mills are available in 1” and 1.25” diameters. Utility cutters that maximize the economy of usage (available cutting edges) are available in 0.75”, 2” and 3” diameters. The maximum depth of cut for 12-mm inserts is 0.430”.
The 12-mm inserts feature a stronge geometry for heavier cuts using small-diameter cutters. Inserts are available with an APET cutting edge for high performance milling of most hard steels and cast irons, or an XPET cutting edge for soft steels, stainless steels and high temperature alloys.
