I bought 3 Powertec 1/4 in. Shank Spiral Router Bit with Up Cut, 1/4 in. Cutting to start my collection of 1/4 shank cnc bits. I am getting close to getting my 750mmx 750mm OX cnc built and I been thinking about my first project on it and I am going to do some different size trivets for my wife and mom. From small to large and I figure the 1/4" width would be perfect. I am doing a cross pattern. I will post on my build and my first project when I get done.
