0.5mm Carbide Square End Mill Bit
These end mill are slightly different than PCB drill bits. Drill bits can only cut in an axial direction, meaning in line with the axis of the bit – or up and down on the PCB. End mills can move in any direction so you can drill side to side, up and down, etc. The cutting part is made from tungsten carbide and are suitable for circuit board cutting and probably some other soft metals and other materials. Each endmill has a high hardness, wear resistance and strength and they’re also super sharp which helps when cutting thru PCBs.
