- Does anyone sharpen his own brad point drill bits?
- Is it worth the time (probably not, but is a challenge!)?
- How do you go about it (wheel / stone / file/ ...)? Thx
I sharpen my own bits, on a grinder. I don't find it hard at all, but then again when I started cabinet making you couldn't by them so had to grind your own from high-speed steel bits. I still do the same. I have tried purchasing a few but have found that they invariably need touching up before use so have just stuck to making my own. Like all things it takes a little practice to do it free hand. In the early days I had to grind a few bits off square and start again to get them right. John

I've been wondering that myself. I found this:
And there's a couple pictures. You're doing it by hand and by feel. But you have to keep those spurs at exactly the same height.
Drill doctor website says it'll sharpen 'em - if you don't mind turning your brad point into a regular bit.
I've found a few entries in some woodworking forums. All of them say they throw the bit away when it gets dull, so they take great care with the ones they've got.
I've found references to some attachments for something or other that claims to sharpen brad point bits. Haven't found the thing yet, but some of the references indicate it's really expensive.
Bottom line is, either you go at it with a small triangular file and be really careful and probably mess up a few bits before you get good at it (that's been my history with such things, anyway), or you get a new bit. There might be professional sharpeners out there. Haven't found one yet.

:-) When they say "Call or email for prices", I pretty much figure it's out of my budget range.
And since so far, I don't even _have_ any brad points dull enough to either sharpen or replace, I don't think I'll be getting that one.
That model is about $3000.00. we have a lesser model (390) at work that is $1000.00. They are the same process as the drill doctor, just no plastic parts.

If they are really cheap bits, the file is a good way to go.
If they are good bits, though, you won't have much luck - they are probably high speed steel which the file won't touch.
You should be able to find a sharpening shop that can handle the brad points, but unless they are large expensive sizes it may be cheaper to buy new ones.
