The Handy Man that is doing the tile project in my house has burnt up two drills mixing the tile mix and I let him use my Milwaukee battery powered drill but ain't wantin him to burn it up too,,,,!!!!

 The first one to go is a Hyper Tough 5 amp 3/8" Electric Drill that needs brushes, SN is AQooo17G,,,of coarse it is made in china. Anyone got a source for getting a set of brushes??  It IS a really well made drill and just needs new brusshes.

 The other drill is a Big Craftsman 1/2" but cannot read the rest of the tag, It has a big "D" shaped handle at the rear of the drill. It also needs brushes too.  The biggest issue on the big one is the bearing at the chuck area has some play but I cannot figure how to remove the chucck to get to that bearing,,,and I think it musst be threaded onto the shaft that the main input gear is .  My question here is,,,is the chuck screwed onto shaft right handed or left handed,,,don't want to mess up the gear,,,,,

 Thanks for any help,,,,!!

  Hey Lou and Steve,,,I took and cleaned the hole down the cchuck and I did not see anything that might be the head of a bolt,,,I used a mirror with the sun behind me and can clearly see the flat end of what appears to be the end of the shaft and one or two threads,,,,I put some rust penetrant down the hole and it cleaned up pretty good,,but no bolt head,,,?? IF there is no bolt,,which way would the threads be? It doesn't make sense as it IS a reversable drill and would almost have to have that bolt to "LOCK" the chuck onto the shaft,,,,but there ain't one,,,,,

 WELL,,,GUYS,,,MY AZZ IS THE BLACKEST ON THIS ONE,,,!! I knew I had to not be telling the Troot,,so I added some rust remover into the chuck cavity and let it set for a couple of hours,,,and ,,,and,,,LO & behold,,,there are some threads down at the btm of the chuck , obviously on the end of  the motor shaft,,,,!!!  I'll be go to haides,,,,,,,I DO apologize Guys!! The threads were completely covered up with all kinds of acumpocky,,,, I had removed the front section that has the big gear, the shaft and the chuck and the big gear sure looks like it be pot metal, so I don't want to jam something metal against the gear to try and break the chuck loose from the shaft,,,guess, I'll try some heat on the chuck first and use some vice grips on the chuck see if I can break it loose from shaft,,,,,

  ( Trying to make up for my screw up)

 There was this dude that followed a teen age girl into the women's Rest Room telling some other women  that he identified as a woman,,,,next thing he realizes he is on the ground trying to spit up half of his teeth,,,,,,The 6 foot angry man tells the dude on the floor,,,I identify as the Tooth Fairy,,,,,,,

I don't know how old the one I have is, it was my dad's and I have no idea where he got it. I doubt he bought it new 'cause he wouldn't have had enough use for it to spend that kind of money. 

Anyways, this one is a Craftsman, 1/2" geared drill. I suggest not using the trigger lock feature! I was drilling a half inch hole in steel, the bit caught as it broke through, whipped around darn near broke my wrist (as it was wrist swelled way up and was the meanest black green blue for a week or so) then proceeded to roll across the yard winding itself up in the power cord until it pulled the plug out of the extension cord.

It's chinese but most everything is these days. A battery and charger will cost almost as much as the tool but can be used on other Bauer tools also. They are pretty good tools. Good luck on getting those drills repaired.

 Well,, I finally got the danged chuck spun off the drill,,,whew!!! I had to use some heat down the center of the chuck and used a big pair of vise grips,on it , heated it up GOOD and hit that vise grips with a good sized ball pein and she come off pretty as you please,,,i forgot that sob was hot and almost burned my fingers when I tried to catch it. The end of the drill shaft IS threaded but lock bolt been gone for long time. I went to The Alien Town today to Westlake Hardware (Ace Hardware)and they had lots of brass bushings and I fount one that matches the old brass bushing to a "T " ( 1" X 3/4" X 1" long,,just got to machine the flange off the new brass bushin,,,,,,finally something started going my way,,,,

Yeah, Hubert,,I showed that one to him and going to HF  he is enough old fashioned,,he won't use a battery powered anything even after I showed him my Milwaukee will mix that mud pretty good,,,,

 Well, Good News,,,I got that 1/2" drill all cleaned up and that brass bushing I got from Ace Hardware fit like a glove,,,and,,,and,,,it runs like there ain't no tamarrow,,,, I'm really liking the varible speed for mixing some heavy Duty Chit,,,I'm still laughing at ole Lou scrambling out of the way of his big old drill chasing him across the field,,,,,!!!!

  Only'ist thing I got to do Now  is find the bolt that locks the chuck onto the drill. Went to both hardware stores and three car parts stores and NOBODY gots a 5/16" Fine thread "LEFT HAND" bolt,,!! I tried a 1/4" Rt hand and a 5/16" Rt hand and no go. It is a 5/16 left hand thread so maybe fastenal or Ebay or,,?? Maybe I'll just drive up to the Alien Town to that big Ace Hardware,,hope they gots one,,,,

 Hey Thanks, Dave,,I gots a McMaster-Carr catalog here,,,,somewhere...I just gotta remember where in the heck I left it,,,,,,

You can go to their site, and enter in the bolt size, thread and lh, and it will pop right up. About $12, IIRR

 Probably a bargain when you consider what a new drill would cost that will do as much work as old will before it rests again.  Or how many of the cheap ones it would take to do the work the old one can still get done.

But still a bit of sticker shock to me.

 Chit,,Steve,,,my azz is the blackest again cause it is a 1/4" fine thread bolt in left hand thread and McMaster-Carr does not have one.  I had planned to buy a short head socket head  type  bolt and then reduce the OD of the head on my lathe to make it fit down inside the chuck but that ain't gonna work if the friggin bolt is not available in Left Hand FINE thread,,,,

 I "save" some of my old tools and am gonna look thru the box as I know there are at least two other Craftsman drills that "MAY" have that elusive bolt in em so,,,wish me luck,,,, If not maybe some other "current brand" of reversable drills use the same bolt that I might could buy,,,,??

 Hey Thad,,,you mean like the RED Thread locker,,? I did put some of that "RED" thread locker on a bolt on one of my chain saws,,,,dang near had to tear the engine up getting the friggin bolt back out,,,!!!!

 Hey Steve,,,Dang,,,but you got some danged good sources don't you,,?? I'ma gonna call em in the morning,,,  Many THANKS Guy,,,!!!!

Drill chuck I think I would use blue if you ever want to get it off again.

Red you have to heat it up some to get it off.

My opinion.

When I saw Old Craftsman Drill in the title, I remember when I was a teenager my dad had 2 of them. Aluminum case 1/2" and 3/8". I was using the 3/8" in the basement on concrete barefooted. Lit my ass up. Couldn't let go of it. Weird part was I could still think and knew what was going on but couldn't let go of it. Finally shook it loose and knocked me stupid for the rest of the day. Dad took a sledge hammer to both of them after that.

The drill caught the cut off fringe, winding his hand so it stuck the trigger on, started rolling up his pant leg.  Was a race between winding the cord around the drill and crushing his nads.  Lucky for him, the cord wound itself enough to pull itself out of the wall!  He said, he was way too frozen dumb to do anything else!!!!  Try that with a cordless!!!

Well,,I've also had my share of "Assults with a Deadly Weapon" with them drills and grinders,,,,!!  Back when I could still work two 8 hour jobs,,,,,I was helping my buddy work in his body shop and,,,I'ma tell ya'll something,,,I was a TERROR on dismantilling them crushed up front ends,,,, but the real work started when you had to do the body work which entailed using one of them HEAVY ASSED Black & Decker 7 1/2" grinders to grind down the Bondo,,,that was sometimes  was,,,,kinda thick ,,,, Anyways that friggin grinder slipped outa my hands,,and cut a BIG slice outa my right leg bout 8" long and bled like they was no tamarrow!! They had to take me to ER to put 12 stiches in it and to this day the scar is still bout 6" long and 1/2" wide,,,so much for them stiches,,,,

 Hey Steve,,,YEA,!!  that is the exact drill as mine,,the tag is just about gone on mine but last 3 numbers are 280,,,, same as the one you posted  Well,, we now gots a PN for the bolt,,not that anyone has one in a Sears store hid out somewhere,,,?? I called that outfit you sent that link on this Am but it was too early and not open yet,,then I got to applying the grout on the floor project and thats where I am

  Dang,,,,Michael,,that right there is a BRUTE of a drill ,,ain't it,,,??  CHIT ,,I'd be scaird to use that big sob unless I could chain it down to the loader on the D14,,,,,What is that part you looking for on the big ole Drill,,???

 STEVE,,,you ARE something else,,,,!! Proud to call you my Friend,,!!  I had gone to the hardware store and looked thru their bolt section and tried a 1/4" fine on the shaft but was a tad small,,so then tried a 5/16" fine thread and it fit better but hard to say definately because these were not left hand thread. I'm pretty sure the 5/16 one you fount will do the job !  

 Dang,,I owe you so many favors,,I'm just gonna have to break out ole Shameless's stash of Black Label and send you a sixer or two,,,,I know he won't mind since it IS for a good cause,,,,,,
