Long Foam Cutting Tools EPS Milling Router Bits Ballnose Flat End and Conical These big long series foam end mill, ball nose and conical router bits are widely used with robot milling machine and huge CNC router which used to cut molds from EPS foam, polyurethane foam, Polyfoam, eva foam, plastic, etc. The long foam cutting tools are great for extended reach machining, deep foam cutting, cnc sculpting big items, cnc routing foam. They are helpful mills for building cnc foam moulds and for advertising signs making. Long Foam Milling Cutter Tools Features: 1, High Speed Steel (HSS) hardness: HRC 61-64.5�° Super hard high speed steel (HSS) industrial router bits provide deeper cuts and larger slices with fewer passes in thick foam, resulting in improved productivity and less assembly. 2, Sharp spiral blade for clear smooth finishing (4 flutes or 6 flutes or 8 flutes), more flutes will get better finishing surface, The up cut spiral design removes chips away from the workpiece. Unlike straight fluted tools, the chips are effectively flowing out of the milling channel and thus avoids clogging of the cutter tool. 3, Extended Reach for deep foam cutting, carving and milling 4, Foam milling bits size could be DIY customized
