<p>0-flute bits are the go-to endmill bits for all things acrylic with CNC routers. If you haven't created LED-lit acrylic projects, it's definitely time.</p> <p>Or if you want to make projects from aluminum, this bit will work on that too!</p> <p>This is a set of bits (specs below). You are getting 1/8" and 1/4" diameter bits to make sure you are ready for both small AND big jobs!</p> <p>Both acrylic and aluminum require a high-spiral bit that minimizes contact with the plastic to prevent melting, which 'galls' the material to the bit, making it ineffective. This also virtually eliminates the other enemy of cutting plastic...melting it and causing it to bind to the cut surface.</p> <p>This set contains one bit of each size.</p> <p>All bits on this site are made of carbide steel. Carbide is what professional metal machinists use to make complex items like car engines. It stays sharp 50x longer than conventional CNC router bits.</p>
