2 flute up spiral solid carbide router bits

If you're looking for a great finish on the bottom of your material, then a good quality up shear router bit is what you need. These are most popular spiral router bits used. Great for fast routing, excellent chip removal, best in natural wood fiber. If you use a vacuum system to hold your material on a cnc, be aware that these bits will try to lift the material being routed, in which case you may want a down spiral bit.
