I've bought plenty of MLCS bits over the years which have mostlt
served me well. The only exception is on a set of spiral solid carbide
bits. They barely cut at all. But they refunded my money and shipping.
I subsequently bought a spiral solid carbide bit from Infinity and
that sliced right thru the wood. The difference was so astounding that
the next time I buy a bit, I'll try infinity again. I believe that the
bad MLCS was a fluke and I wouldn't hesitate to order from them again
either.
