Re: Brass for the first time on my Stepcraft
Brass can be a real bugger to cut if you have a positive rake angle on your cutters. You need a zero rake angle to stop the cutter from digging into the metal. Are you using a spiral end mill? Try a straight sided milling cutter like the one below and if you can just hone a flat along the cutting edge to make it zero angle ( I would try it without doing that first though ). Try a wood router bit if you have to. You also need a fast spindle speed.
Hope this helps a bit.
