Detailed Description
Consists of 10 different solid tungsten carbide drill bits made for PC board hole drilling. These came from a PC board manufacturer that closed and may have been resharpened or used drill bits. Each bit has a small collar on it and most have the size marked on it (some sizes may be metric). Bits range from big to 80 (very tiny). All shanks are standard 1/8". These will drill thousands of holes in PC boards, however you should use a drill press as flexing these tiny bits will break them! This is our best assortment- We find these bits very useful when making PC boards here at the Goldmine. G15421

When drilling thin stainless (like a sand scoop), you need to plunge drill it. If you drill too slow, the stainless work hardens, gets harder and tougher, then it is very hard to get a hole through it. Use lube also (bacon grease is a good cheap one and stays where you want it). Don't use this method on anything but stainless and it does not work on some very hard stainless. Also a Friend of mine, that makes knives, got a high speed burr at Lowe's that cuts right through hard stainless. He said the clerk told him about it.
