I've used WT's, HF's, and drills from the guy who sells on Ebay - all have worked equally as well. The clincher on the resharps is the length from the collar to the tip is a bit shorter and not consistent. This is generally only a problem on automatic equipment though - especially multi spindle and tool changers. In my case, I can set the depth at which the slow downfeed starts for each hole, so while I may have to measure the drills length before using them, they work as well for me as new drills. As for sizes - the EBay seller's kit box seems to be missing sizes between .020 & .036. I would think there would be more interest in these sizes. Does the auction list any other tools that you are not so interested in, but that we might be? C -- http://www.piclist.com hint: The PICList is archived three different ways.
