Drilling bit for knife handle
« on: March 16, 2011, 04:37:38 AM »
I bought a carbon steel blade from Atlanta Cutlery to make me a ball handled knife, got the blade an handle shaped like I want it but the predrilled holes don't align now so need to drill a couple of new ones, problem I'm having is its eating up my drill bits, I bought some titanium drill bits a lowes yesterday and they started to drill then just started squalling and spinning with out cutting, putting oil on it an trying it doesn't work, I can't anneal the thing cause I've no way to re-temper it does anyone know of a bit I might use to drill this thing, don't know what type of carbon steel the blade is but is definitely is good.

  If you live close to a tool supply company you can try carbide. ( a little pricey for what you get). Sounds like the tang is full hardness. I take it you ground the blade to shape..  You could try and make a heat sink by wrapping the blade only in a wet cloth, while clamped in the vise. Try drawing the tang back with a torch. You might get enough to allow drilling..

I'm with Dave on drawing the tang.  If the wet rag does not appeal, stick the blade in the ground outside and use a torch, or stick it in a potato, squash, watermelon, pumpkin etc for grins.  They make good heat stinks.  I meant sinks  ::)

Try a Cobalt bit. That will drill spring steel ,stainless etc. However you have probably hardened the places you were trying to drill to the point where annealing is the only answer.

I would do as Dave & Rich suggest: anneal the tang.  A tang that hard is a recipe for disaster down the road if a hard blow is directed at the knife, a broken tang can make fightin' that grizzly off !@*%&@ difficult! ;-)
