I just have gotten done with a carve I modified the ornamental box and used the ER-11 and the bits that bergerud had suggested on getting from DHgate I am very pleased with the bits that I had ordered I bought 15 of them for $2.00 apiece and I was a Little Leary of the bits being from china, I didn't leave the machine, I made pocket cuts and the cut outs. It's become my bit of choice....Thank you Bergerud...Job well done, Sir
