If you're designing PCBs in Eagle or KiCad and want to turn your designs into real PCBs, a CNC mill can cut away copper trace outlines. We first got these end mills for our Othermill, and they'll likely work well with many precision CNC machines. Unlike our PCB drill bits, end mills can move in any direction, not just axially. The cutting part is made of tungsten carbide, suitable for circuit board cutting and some soft metals. Each end mill is hard, wear - resistant, strong, and super sharp, which makes cutting through PCBs a breeze. It has an 8mm flute, a bit longer than usual but works great and is affordable to replace if it breaks. Even carbide bits will dull when cutting PCBs, and you can cut for about 5 hours per bit before replacement. This product comes with one 0.6mm carbide end mill in a protective plastic case.
Using this end mill is easy. Just install it in your precision CNC machine. You can use it to cut PCBs, moving it in any direction you need. When cutting, remember that the bit will gradually dull. You can expect to get about 5 hours of cutting time before it needs replacing. Since it's made of tungsten carbide, it's quite hard, but it can still break. So, be gentle when handling it. After use, store the end mill in the provided protective plastic case to keep it in good condition. If it does break, don't worry, as it's low - cost and easy to replace.
