Drill bit sharpners?????
 
Dedicated electric models, not jigs for a grinder.



Do they work. Do you have or used one. Worth the money. Brand suggestions?


In my mind if doesn't do at 1/2" bits it isn't worth buying.



Whatever else I might want to know.

When I was younger I often thought about buying one but couldn't justify spending the dollars that were in short supply. I have gotten fairly decent at sharpening bits on a grinding wheel. The bigger the bit the easier it is to eyeball the angle.

Ayuh,.... I've got an antique(60s, maybe 70s vintage) black, 'n decker drill mate,.....

It works just fine, so long as I use a light touch with it,.....

A Bud has an older drill doctor, that I've had pretty good results with too,....

I've thought about a bit sharpener, but with the low price of replacement bits, it just doesn't seem like it's worth the time and trouble.

For small diameter holes, you can even buy a small pack of "throwaway" drill bits at the Dollar Store, and save your premium bits for where they're really needed.

When you get into the 3/4 inch or 1 inch bits, the bit sharpener makes a lot of sense, if it even goes that large. I have found the cheap bits don't hold up too good when drilling thick steel. I have used some from Harbor Freight and they actually would bend instead of break.

I've read dozens of mixed reviews, probably only about 25% saying that they work OK. Bits are not expensive, so my 30,000 foot perspective tells me to just replace when worn. My time is worth more to me than the potential scrimping on a few pennies.

I learned how to sharpen them freehand in the late 60's early 70's but I was a machinist, now retired. You learn what to look for in the shavings and adjust from there. Of course you are striving to match the original grind in most cases. I thought the smaller ones were easy and any thing over 5/8" was more difficult. I've done up to 2" diameter freehand, that wasn't easy, also wasn't easy on our drill grinding machine so..........

One of my frustrations is sharpening, in general, but drill bits to be specific, and not that I don't see the importance of it, but it's just not one of my strong suites. So I figured it was worth a shot, bought a Drill Doctor maybe 10 years ago, and am very pleased with it. I know others who are less than pleased with their results, but honestly believe, in some cases anyway, it's the fact that it looks easy enough, and think that some people don't pay attention to detail when they use it. I don't use mine regularly, maybe every couple of months because I put ones that need it aside to do all at one time, read the instructions again, and by about the third one I'm on a roll.

I don't use it often but I've had a drill dr for a couple decades now (I think) and it works pretty well.

I'm 68. I have to ask myself how many more bits will I need to sharpen or replace before I hang up my tool belt?


From what I've read in this thread and other sources I think the Drill Doctor might be the one but for me the payback probably isn't there.

I have a Drill Doctor, which I bought years ago. I periodically pull it out and sharpen up a bunch of bits. It is very easy and quick to use. It's only made to do twist drills, not anything with and odd shape like the bullet tip bits. It comes in handy when you're drilling steel and you realize the bit is dull as heck. Sharpen it up and it's good as new.

Another vote for the Drill Doctor. With some observations. Yeah, it is possible to learn to sharpen twist drills freehand. I generally lean toward learning how to do stuff like that, but, it's not an obvious process and takes a little practice to do well. I don't sharpen drills frequently enough to have developed and maintain that skill myself. Hats off to those who have. The Drill Doctor ain't perfect. It's mass produced out of plastic such. If you're not careful, it is easy to inadvertently apply pressure to the drill as you're turning it and cause the jig guides to deflect enough that you doin't get a nice symmetrical grind at the right angles. I think that this probably contributes to those who haven't had good results with e Drill Doctor. I think it's worth taking a little time with it, and really looking at where the fixture is kinda flexible and concentrate on making sure you aren't putting any sideways pressure on the drill as you sharpen it.

I've had a drill doctor for ?? (awhile). Used it once. Bits are cheap enough.

Why not read the reviews from dozens of people who have bought these tools on Amazon? I did this and decided for the type of bits that I use that it was not a good value.

I actually did. Then I asked here where there are no people with an axe to grind or fake reviews to post for pay.



I pretty much made the same decision as you.
