Trying to figure out what kinds of 1/8" cutters would be needed for hobby machining. Soft wood like balsa and lite ply where 2D shapes are being cut out. FR4 epoxy pcb material cutters for trimming and a v (?) cutter for circuit isolation. 3D cutting in oak for image reproduction. Where can I get some insite? 20-30K rmp spindle with 1/8" collet.
