Is there a reason why I don't see High Speed steel drill bits offered on the inter-net sties? The cost is about 50 % less. I drilled my first ball this week and they held size as long as you have a 1/2 " pilot drill. They did not pull into the ball material, they cut like butter. I realize that carbide will last 10 times longer before you have to reshapen them but given the cost I would think that they are more cost effective.

I know you can send carbide tip bits off to jayhawk and others online to resharpen, but what type of places locally would do this? I have some that need it, but I don't know where to begin to ask locally.

Might want to check a local machine shop or if there is a tool & die shop close they will probably have the capability also, if they will sharpen them.

Most machine shops have the capability of resharpening HS drills but not all machine shops have diamond wheels for carbide. Start calling machines shops within your area and ask if they have carbide tool bit grinding capability.

Also check places that sharpen blades for saws, chain saws, and other tools. Most of the time they can sharpen drill bits too. My place in Houston did mine for $5 a pop.

BTW, SpareK, you could probably drill 3 holes with a High Speed bit. They are just too soft, not sturdy enough for bowling balls.

High Speed drills don't cut it. Mikes right, about three holes is it. And when they get dull they tend to wander. I don't think it's the cover that kills the drill, I think it's the filler. The filler smells just like bondo and it's very abrasive. I drilled alot of holes with my carbides before I had to have them touched up.

You might want to let some of these guys contact you, you might have some nice side work coming if they can't find someone in their area to sharpen their bits for them!!
