KPeacock Posted August 31, 2009 Share Posted August 31, 2009 I was at the MN state fair over the weekend and while wandering around the product demonstrations I saw a file with about 50 holes drilled in it. I walked over to investigate and was amazed at the set of drill bits this sales guy was demonstrating. He drilled through ceramic tile, keystone retaining wall block, a brick, then straight through a nicholson file, he then drilled into a 4"x4" and flexed the bit to about 15° of deflection to show it's break resistance. The bit got hot enough to readily burn sideways through the wood. The guy immediately drilled through an automotive brake rotor while the bit was still hot. I typicaly don't fall for the sales pitches, but after fighting to drill the tang on my last knife I've been putting off a set of carbide bits. Seeing these in action was pretty amazing. They come with lifetime replacement if they wear out or break. You just send the pieces in to them and they will ship you a new bit, so you're only out 44cents. I don't work for these guys, or know anyone that works for them, but I'm guessing other folks have had a hard time drilling through knife steels as well. The 13 piece set was $90 at the fair. I think normal retail is a bit higher, but I've ruined about $100 in drill bits in the last year anyhow. I figure these will pay off in the long run. Here is a picture of a new nicholson file that I drilled through so you can get a visual of it. http://www.rodmanandcoinc.com/rodmanandcoinc.com/item04c5-2.html?UCIDs=1307321%7C1307323&PRID=1492961 Have you ever thought about the life of steel? It's interesting to think that you can control the fate of a piece of metal. Link to comment Share on other sites More sharing options...
