PCB board and Bits /recommendations and suppliers

[HankMcSpank]

Thanks. Those are the kind I was meaning, I was concerned they would not give as good a finish as the fluted type I currently use.

Also while searching around the forum, I think you said that those ebay spade ones lasted longer than the fluted one you tried? I've not worn mine out yet, but not done that many boards.

certainly a fresh new spade cutter gives superb results (not sure which of my former posts you refer to about the longevity of the spade type - but I don't recall comparing like for like against fluted bits) ...alas, since I'm forever making schoolboy errors (spade descending way too deep into the board & too fast into the board ...the 30 degree spade cutters don't take too kindly to that), it's hard to be precise how long one would last without my mistakes!.

The other benefit of milling paper based board (aside from the more lung friendly dust) is that the board is more easy going on the cutter...afte all, it's just a skimming of copper on top of paper.
