I went to Lowes today and they had a set of Bosch router bits on sale. The sign said marked down from $89.00 to $69.00. When it rang up at the register it was $56.00. Some of the bits would work for the Shapeoko but I also have a Dewalt 611 with plunge base. So I bought the set mainly for that. Pretty good deal for good carbide bits with 1/4" shanks. I have a lot of router bits but before the Shapeoko I tried to buy 1/2" bits. So I dont have as many 1/4" shank bits as 1/2" shank bits.
Do not use bearing type router bits on a CNC. Pretty good deal.
