Are you suppose to use cutting oil with this? Would it be better to drill a small pilot hole with a carbide drill and widen it to 1/4 or just go for the 1/4 carbide drill ?? Help!
 
Generally speaking, with carbide in steel, oil is not necessary.

Preventing chatter is necessary (with carbide), which means a rigid setup and using appropriate speeds and feeds.

Carbide drills can chip if overloaded while exiting the back of the material. Drilling through into a scrap piece of material prevents this.

If you're "drilling" with an endmill you certainly need a pilot hole because the center of the cutter does not cut well, so your cutter wobbles creating a bad hole.
 
Nathen: I mean should i just buy the 1/4 carbide and drill or would it be easier to drill a 3/16 and then use the cutter to take it to 1/4? Stupid ? i bet.
 
This drilling of hardened damascus is getting me crazy. Got two blades coming with no holes at all. Nathen! How about i mail them to you and you can charge me for drilling???? :)
 
If you are just drilling in the tang area, set the bade up in water or the like and heat the tang area you want to drill up untill it is red then let it cool slowly and you should be able to drill it easy with a decent bit. What type of damascus. Might not work on stainless, should work on 1095/15n20 and the like. I have some 1/2" aluminium plated I clamp to my blades when ever I use heat to solder or do something like this.
 
Not sure what type but not stainless. I tried the heat and still no go. Intend on trying the carbide drill but can't afford to break them! :(

If you pay return postage and $5 for the cutter, I'll be happy to cut a few holes for you. Send me a PM.
