    I picked up a couple of bits and have been trying them out this weekend. No problems at all with the ER11. What were your thoughts on them?

    I may be imagining this but to me they don't seem as sharp as some of my other bits. Could be the one I'm using only since I haven't tried the second bit yet.

    I think you are right. The bits with the coatings do not initially feel as sharp as the bare carbide bits. The theory is that they stay sharper longer but I do not know if that is true. The coatings may reduce heat and chip friction. For wood, I wonder if it really matters that much.

    Dan, thanks. Good. That means as the coating wears off the bit will get sharper.

    I'm going to try these! Are you using any particular 1/4 - 1/2 insert? Also, do you have to use the little clear plastic spacer anytime you use an insert?
