Carbide Square End Mill - 1/8 Shaft - 0.8mm Diameter

If you're into designing your own PCBs using Eagle or KiCad and want to turn your designs into real - world PCBs, a CNC mill is a must - have. It can precisely route out PCBs by cutting away the copper trace outlines. We first got these end mills for use with an Othermill, but they'll work great in many precision CNC machines. Unlike regular PCB drill bits that can only cut axially (up and down on the PCB), these end mills offer more flexibility as they can move in any direction - side to side, up and down. The cutting part is crafted from tungsten carbide, making it perfect for circuit board cutting and also suitable for some soft metals and other materials. These end mills are hard, wear - resistant, strong, and super sharp, which is a big plus when cutting through PCBs. They have a relatively long flute of about 8mm. Even though it's longer than what we're used to, they perform well and are affordable to replace if they break. Keep in mind that carbide bits will dull over time when cutting PCBs. We found each bit can last about 5 hours of cutting before needing replacement. This product comes with one 0.8mm carbide end mill neatly packed in a protective plastic case.

Using this carbide end mill is easy. First, make sure your CNC machine is set up properly. Insert the end mill into the machine according to the manufacturer's instructions. When you're ready to start cutting your PCB, choose the right speed and feed rate for the best results. As for movement, you can direct the end mill in any direction you need - side to side or up and down. Remember, the end mill will dull after a while, usually after about 5 hours of cutting PCBs. So, keep an eye on its performance. If you notice it's not cutting as smoothly as before, it's time to replace it. Also, always store the end mill in its protective plastic case when not in use to prevent damage. This will help keep it sharp and ready for your next project.
