You HDT folks are real do it yourselfers so I thought somebody could use this.  The price of a Drill Doctor put me off from buying one.  The link is to the Tips and Tricks forum.

Maybe you could interest someone in buying you a Drill Doctor for your birthday or Father's Day or Christmas or ...

I have one . Way quick and easy . ;)

When I was young and steady, with good eyes, I could sharpen bits by hand nearly as well as any machine.  That was some time ago.  Now I use my Drill Doctor, especially on split points.  I still do them by hand if I only need to do 1 or 2, but it sometimes takes a couple of tries.

A Drill Doctor is money well spent.

I barely even look at the point any more  ;)  just takes a little longer to drill the holes now.   Just kidding.  I think I will be buying new bits before I spend the $$$ for a Drill Doctor.  The D.D. costs more than I thought they would.  $50-$60 up to 1/2".

I just go out to the driveway and make circles with my old bits.  Works every time.   😗

I got lucky. I bought a “new in the box never used” Drill Doctor at a garage sale for $10. Haven’t used it yet though and it’s been over a year.

I did that for years . Probably way more than a decent set of bits and a Drill Doctor combined . 

Sure you won't use it every day , maybe . But , it'll likely never cost you a penny for another set of bits . ;)

I keep mine in a zip lock bag . The dang thing looks as good as the day I got it and does the very same job .

It's one of those convenience tools . That's why you have to get it as a gift , so you won't feel so bad . :D

When I had the boat company running, We bought one of the higher end Drill Doctor models.  It paid for itself in 1 day.  Fiberglass is terrible on drill bits.  From 1/16 to 5/8 we used daily.  The small bits are cheap to replace but once you hit 1/4" or so, dulling 2-4 a day gets expensive.  

If I was doing enough work on the truck or remodeling the RV, I would invest in one.  You won't use it often, but a sharp drill bit is handy.  

For truck work, consider a set of reamers, or Bridge Reamers.

Buy quality bits and keep them sharp.  The difference is amazing.  You, and your drill, will last longer.

It has been many years since I built the bed for my truck.  We carry a car so the bed is longer than many.  I didn't have a mag drill so the many holes on the frame and some other places that couldn't be done on the press, were done by hand.  I used the DD after every frame hole.  Without it I might still be drilling.

IMHO, the DD is worth every penny spent.  I have had mine for at least 15 years.  I now only use Cobalt bits, which are more expensive.  They get dull too and the DD will quickly bring their sharp edge back.  I have the second adapter that allows me to sharpen up to 3/4" bits.  I also have several other drill bit sharpening jigs that attach to my bench grinder - but the wheel on the bench grinder needs to be kept in really good shape.  My grinder wheels can take a beating making for an imperfect bit tip.   The DD is so fast and easy owning one to me is well worth its cost.

I spent three months hand grinding drill bits during my apprenticeship.

I could get a good point on bits as small as 1/16" with a good grinding wheel.

Ever since we got a good drill press and learned how to use cutting fluid they last pretty good. By the end of they year there are always some broken and lost. Trade in the old set for a new one. I keep one set on reserve just in case.

black and decker 4300 found on ebay. not sold new any more. Will sharpen any bit up to 5/8 like new. Yesterday while adding generator to my Volvo 2 bits went dull. Pulled it out and sharp bits again. It will pay for it self quick and you don't have to wait a year to get new bits. I am too old to wait a year for a new sharp  bit. Check it out.

That looks pretty simple.

 

My boss went and bought one of these things that bolt to the bench after the drill DR burned up. He was all excited about it. until nobody could figure out how to work it. Now it just sits there in the way. I took it off one day and he got all mad because hes going to figure it out some day. Its been there for 2 or 3 years.

Have a moderate number of holes to drill coming up. Also have a peach basket of old, broken, and dull bits. So, properly inspired by this post, I ventured forth, bought a DD, returned home & fired said machine up. 20 minutes later, happy happy, all sharp bits. Who knew. My dad had all manner of little electric whatzits, none of which worked worth crap. The DD doesn't seem to fall into that category.

Paul,

Did Paula let you sit in your recliner and watch NASCAR while you sharpened your bits, or did she banish you to the shop?

You know how "fiscally sensitive" I am, and I like my DD.  Money well spent.

I have sold both.  The  $37.00 one is junk. Look up a used one on ebay and you will be happy.

I have sold both in the tool truck. The one for $37.00 is junk. Find a used one on ebay and be happy and sharp.
