1. Accurate size: spiral cutter with 8 mm shaft diameter, 12 mm cutting diameter, 25.4 mm cutting length, 80 mm total length, the cutter is very precisely processed and there is no diameter difference between bearing and cutter diameter. This creates a very even edge when flush milling. 2. Ideal for flush milling: Two ball bearings are attached below the milling head, which allow easy, lateral guidance. The CNC cutter with its flush ball bearings is well suited for milling edges flush or copying. Due to the overhead ball bearings, the cutter can also be used as a groove cutter. 3. Sharp cutter: Perfect spiral processing on the milling head, well made, very sharp cutting edge for burr cutting, good wear resistance, as this is a solid carbide cutter, it is very stable and can withstand high cutting data. 4. PTFE coating: thanks to the PTFE coating of the cutter, the accumulation of wood chips, resin and asphalt can be effectively prevented and the hardness is high, good cutter that leaves a clean cutting edge and eats effortlessly through hardwood.
