A good tool for this can be made from an old tire-iron. If you can reach it, for example another way is to chuck a carbide endmill with a 1/4" shank into a router and use that to re-shape the head.

Answer - The Rescue Bit was designed specifically for the purpose of drilling out very hard metal compounds, like the EZ Out and Cobalt drill bit material.

Can you use a drill bit in a die grinder?
Answer - The short answer is yes, I'll explain. The manufacturer recommends starting off slow. So I'd use a drill first so there's more control. A die grinder will work faster but dulling may also occur faster as well. Most die grinders have a 1/4" collet and some come with a 1/8" collet. They never come with the 3/16" collet, so we suggest buying the 3/16" collet if you want the capability of using a 3/16" Rescue Bit in your die grinder. Remember whatever size you use or if it's in a drill or die grinder to use a rounding motion as you go.
Can you use a rescue bit in a drill press?
Answer - Let the Rescue Bit do the work. Drill in a rounding motion to help prevent binding. For this reason, do not use in a drill press, since you will not be able to use the rounding motion while drilling. There are additional tips included with the product that can also be read before purchasing - the tips are linked on our product listings.
Can you drill a bit faster?
Answer - Yes. The maker of the Rescue Bit says that different metals can be drilled best at different speeds. They recommend using slower speeds at first. Increase speed if needed, until the optimal RPM's is determined. Keep in mind that the faster the bit is turned, the faster it will get dull. So there's a compromise to be found. For instance, using in a die grinder will work faster but will dull faster as well.
