We initially ordered these end mills for our use with an Othermill but they will likely work great in a wide variety of precision CNC machines.\u003c\/p\u003e\n\u003cp\u003eWhile we already carry PCB drill bits, end mills are slightly different.  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 \u003cstrong\u003ecan move in any direction so you can drill side to side, up and down, etc\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp\u003eThe cutting part is made from \u003cstrong\u003etungsten carbide\u003c\/strong\u003e 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. These mill bits have a fairly long flute, about \u003cstrong\u003e8mm\u003c\/strong\u003e. While this is a bit longer than we are used to, we have found that the bits work quite well and are low cost enough to replace if they break. Note that even carbide bits will dull eventually when cutting PCBs, we found we could cut for about 5 hours on each bit before we find they need replacing.\u003c\/p\u003e\n\u003cp\u003eThis product comes with one 0.8mm carbide end mill in a protective plastic case.\u003c\/p\u003e\n\u003cp\u003eView our full range of Adafruit products here.\u003c\/p\u003e\n\u003cp\u003e\u003ciframe width=\"560\" height=\"315\" src=\"https:\/\/www.youtube.com\/embed\/UZ8GDS36BN4?si=2g_x9dFIwDEipFWx\u0026amp;start=822\" title=\"YouTube video player\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eTungsten carbide end mill for CNC PCB routing and circuit board cutting\u003c\/li\u003e\n\u003cli\u003e0.8mm diameter bit with 8mm flute length\u003c\/li\u003e\n\u003cli\u003eMulti-directional cutting capability (unlike drill bits which only cut axially)\u003c\/li\u003e\n\u003cli\u003eHigh hardness, wear resistance and strength\u003c\/li\u003e\n\u003cli\u003eSuper sharp cutting edge for clean PCB traces\u003c\/li\u003e\n\u003cli\u003eCompatible with precision CNC machines including Othermill\u003c\/li\u003e\n\u003cli\u003eApproximate cutting lifespan of 5 hours before dulling\u003c\/li\u003e\n\u003cli\u003eSuitable for circuit boards and soft metals\u003c\/li\u003e\n\u003cli\u003eIncludes protective plastic case\u003c\/li\u003e\n\u003cli\u003eLow cost replacement option\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eTotal length: 38mm\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e1\/8\" Shank\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eDiameter: 0.8mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePackage Contents\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e1x Carbide Square End Mill - 1\/8\" Shaft - 0.8mm Diameter\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Adafruit","offers":[{"title":"Default Title","offer_id":44930777579609,"sku":"yzx1789672894598","price":3.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0736\/5289\/5833\/files\/carbide-square-end-mill---18-shaft---08mm-diameter_1.jpg?v=1789672898","url":"https:\/\/gymflexfit.shop\/products\/carbide-square-end-mill-18-shaft-08mm-diameter","provider":"My Store","version":"1.0","type":"link"}
