I've decided to use carbide drill bits from now on. How do you sharpen your drill bits? I've tried holdng it on the rest of the contact wheel, but I want the angle to be precise. Does anyone us a drill sharpener? I should have gone with carbide a long time ago, they drill the handle holes so nicely,but they are expensive ($25.00 for a .2570).

Bill,I've been making Knives a long time,but have never had any luck sharpening drill bits by hand.I think the best bet is a tool called the "drill doctor"or some such.I think they run about $125.-$150.they will do carbide,118,135deg.,split point etc.,watched a guy use one once,did a bit in 15-30 seconds.Home depot and the like carry them.Hope this helps.

Why carbide?
I usually break a carbide tool before it gets dull.
Carbide is hard to sharpen without diamond abrasives.
I use COBALT or H/S steel.I don't bother sharpening, for a buck or so I can use a new one.

I have ruined too many parts using dull or resharpened tools.Wobbled out holes, swell ring pushed up around the hole, hardened surface inside the hole that breaks taps, ect..., It's worth another .87 cents to avoid all that.
Carbide drills are not recomended for general use.
What are you trying to drill into?

I'm drilling alot of holes in full tangs for weight reduction. Had a bit break off while drilling through a 416SS guard and O1 blade. You're right, I could use a new HSS bit every time cheaper than using one carbide. I just got some cobalt bits and will see how long they last. I'm just tossing dull bits.

Bits are easy to sharpen. It is the first skill you learn in a machine shop class. Hold the bit level with the floor. Match the drill cutting angle to the grinder wheel. Push bit stright into the wheel. At contact drop the back of the bit stright down. Do both cutting edges then measure both sides to make sure tip is in center.

Rick,
you make that sound so easy.
I'v been sharpening drills for years, it just takes practice.

Cobalt will work well for you.
How fast are you turning?How thick?What mat'l?

Cobalt is the way to go. I just wasted $75 on some titanium nitride coated bits and they are utterly JUNK!! Some of the bits would not even finish 1 hole! HSS is good too, but I think the cobalt more durable.
