Drill Sharpening Weekend!!!!

[img]/wwwthreads_images/icons/laugh.gif[/img] I see that Jo-Jo's thread got quite a few hits on the drilling techniques which is actually drill SHARPENING techniques, and I want to caution you that drills will not always turn out OK on the first try. You'll have to go back now and then, but that's OK, you'll eventually get it right. Just don't SETTLE for a lazy cutting bit. GO BACK and try re-shaping and soon you will be making those professional-looking shavings that you see in the machine shop, that are working their way across the floor out the rear door and into the alley, while the overall-clad grizzled old machinist leans back on the bench and keeps an eye on the cut.[img]/wwwthreads_images/icons/smile.gif[/img] When the crap REALLY comes down and we have to make our own guns, these skills will be handy to have[img]/wwwthreads_images/icons/crazy.gif[/img]

Re: Drill Sharpening Weekend!!!!

Dave

Question .

Is there any particular grinding wheel you are using for sharpening the bits or is it just a standard 6" bench grinder ?

Here in Canada they are trying to ram this gun licensing down our throats by the new year . Whats a gun owner to do .

Jeff, are you joking or haven't you been here long?[img]/wwwthreads_images/icons/shocked.gif[/img]

There's almost more talk about guns, and how much of a burden it is to be a white male heterosexual in America than there is about Jeeps sometimes.[img]/wwwthreads_images/icons/frown.gif[/img][img]/wwwthreads_images/icons/laugh.gif[/img]

Re: Drill Sharpening Weekend!!!!

Check out this web site.
http://www.jlindustrial.com
Order a catalog, (HUGE thing) and check out what's available.
Wait for the little sale flyers where stuff is cheaper.
They are REALLY expensive on most of the stuff, but they print a great catalog.

Drill bit sharpening takes an EDUCATED, STEADY hand or a good drill sharpening guide...
Especially if you want Quad cut or self piloting drills, you will have to buy a guide or sharpening machine.

A specialty stone is required for precision work, but any old fine or extra fine grinding stone will work for sharpening what I call 'Hack' drills.
The ones you use for drilling holes 'about there...' or in wood or something like that.
You won't be able to trust them for say, drilling holes for tapping or pressing in pins, but most people do that stuff just about never....

I have my 'Hack' drills laying out handy, but my precision drills are locked away at all times!!
The last thing I want to see is a new shop kid using a specialty parabolic, left had twist precision sized, extra long reach drill as a punch!! There goes $100 real quick!!
AND IT HAS HAPPENED...

Anybody with kids either is having, or will have the same problem...
If they loose a $2 hack drill, who cares?
Let them loose a $2,000 precision stepped reamer, and see if the deification doesn't hit the rotary wind machine! (sh*t hit the fan!)

Re: Drill Sharpening Weekend!!!!

I hear you on the expensive bits /drills . I had this hub on my CJ with a broken off bolt inside. After extraction failed and it now had a broken bolt AND a broken off easy-out inside I took it to the machine shop and told the guy what was in there and he said he would try and then when I got back a day later he was mad because it screwed up his "expensive" bit . If he thought it wasn`t going to work then he should have turned down the job . The result was the damn thing was still inside the hole , just a bit shorter. Had to buy a used hub [img]/wwwthreads_images/icons/frown.gif[/img] End of story . Thanks for the tip on the catalog Aaron .

Re: Drill Sharpening Weekend!!!!

Couple of comments regarding CJDaves post.

Assume this got started from actually sharpening drill bits. I bought a Drill Doctor a few months back. Works like a champ. Different tip angles as well as split point. My drill bits, which I use on the lathe as well as in hand held drills work fine. Was in a shop a couple of days ago, and the subject of drill sharpening came up. That shop had tried the Drill Doctor and was not real happy with the results. Reason? "It doesn't sharpen like it used to." I think DD says the cutter is good for about 300 uses. Guess is that the shop has far exceeded that.

Second. Dave says, "GO BACK and try re-shaping and soon you will be making those professional-looking shavings that you see in the machine shop, that are working their way across the floor out the rear door and into the alley,"

Last week at a meeting of the Houston Home Shop Machinest Club a member brought in some things he had been working on to show the members. Very casually he took a big chip out of a box and tossed it on a table. "Thought y'all might be interested in seeing a 138 foot long chip." Looked like a long skinny slinky. No telling how long it would have been if stretched out straight.

Re: Drill Sharpening Weekend!!!!

When I was 19 (seems like yesterday) I went to work in a machine shop. My first job was to sharpen about 2000 drill bits they had in a big pile on the floor. Small ones up to about 3"! I built 6 racks to hold all the bits when I was done. When I finished, (weeks later) I could sharpen pretty good. Its a skill I have used many times over the years since. I'm still not sure why they had thousands of $$$ worth of bits in a big pile like that. Maybe they just waiting for some dumb kid to come along and do the dirty work!
