My cord electric dill burnt out.( "craftsmen" :mad: bah junk)) In the market for a new one. :confused: Corded or no batteries, any recommentations ?
:rolleyes: Do the keyless chucks really work especially on high torque work ? smile.gif

I personally have been disappointed in keyless chucks in my Milwaukee drill motors.
I may just have had a couple of bad ones but...
I suppose if I could try a nice ALBRECHT keyless chuck I might be happy.
Jacobs Ball Bearing Chucks spoiled me.

When I worked in a tool shop, the keyless chucks worked well.
On home tools they seem to let the drills slip.
If you will be using all hex shank tools, they will not slip.

Well, there is high torque and then there is high torque. The 3/8" keyless chuck on my Milwalkee 12.5 volt drill holds just fine for anything I've asked it to do. The Milwalkee half inch 120 volt drill has a keyed chuck that really has to be chinched down to hold the torque it can put to a 1/2" or bigger drill. I doubt the Harbor Freight model of either would not do as well.

JD...best hole driller I ever used was a Milwaukee "Hole Shooter" with a keyless chuck...a very heavy duty metal keyless chuck...don't know the brand. Corded, with a detachable cord....I suppose to plug into a 2nd drill, chucked with a different bit? A real torquer.

I have a Bosch keyless, works well for everything i do with it except for the occassional time I used a sander attatchement in it and accidently ran it in reverse which unscrews the chuck quickly enough. Haven't experienced removing a lot of screws at a time so don't know if there's a problem there. Don't think I'd buy a keyed chuck again tho.

I have a Dewalt 12v w/ keyless chuck and it works fine. Some of the problem comes from worn chuck jaws and/or worn drill shanks. At work we have Dewalt 18v and they get heavy use and I have had the chuck unwind or drills slip but still I would not give up the keyless chuck, after having numerous experiences with the other variety. I have used my DW 12v with a 4.5 hole saw and it stood up to it but would have an early death if I persisted, so I went to air tools, alas, tied to an umbilical cord again, but cant burnout that drill!!! Might stall it occationally but never burn up.

Well, I'm currently running three cordless drills and three mains power drills, and there's no argument about which type is more convenient to use.
But each of the cordless drills has a keyless chuck, and if I could change them all for keyed chucks I'd do it like a shot.
(Of course, if all you're going to do is use it as a screw-driver, a keyless chuck is fine -- screw-driver bits are hexagonal and can't slip.)

My only keyless is on a Porter Cable cordless.
It slips occasionally & when unscrewing sometimes unwinds & lets the bit go. Never tried to drill a really big hole w/ it.
You can tighten only to the limit that the drills torque and your hand can bear

JimD- I want to hear about that Bosch keyless. I didn't know Bosch made one. Whats the amperage like? Any slipage with the chuck? How large a drillbit will it accept? What did you pay for it and where did you get it?
I have a Bosch belt sander and a jig saw- they are far and away the best tools I've ever worked with.

I run three drill motors with keyless chucks in the shop. Two Makita drill/drivers and a Skil 1/2 inch drill.
Only problem I've ever had was the chucks unscrewing if I didn't tighten them enough and an occasional slippage from the same source- I didn't tighten them enough. I've taken hundreds of screws out with the Makitas over the years with little problem.
Far as I'm concerned, the occasional slippage would be worth not having to find a key. I don't plan to buy another drill motor with a keyed chuck. Real PITA when you are changing bits often.

Don't remember what I paid for it but more or less mid range, not the cheapest, not a wallet buster either. I'm in Canada, can't remember where I got it, might even have been Home Depot

I'm sold on DeWalts. When I was shipping commercially, most ships I was on had at least one DeWalt cordless drill (one ship had FIVE!). I've had them rained on, dropped, burried in cement dust, used while bearing down hard at full power straight through three batteries, all in a marine environment. Never had the keyless chuck slip for reasons that were the chuck's fault. Wonderful. I now have a 12V cordless that I love and cherish (it has more power, more torque, better battery life and more features than my boss's 18V el-cheapo. You get what you pay for)...

Im a Dewalt fan ! Ever since they came out with keyless I have used them and never looked back.When I was building custom cabinets we
used cordless all the time ,I found them to be
a big pain in the rear!Always messing with batteries and chargers etc.Now that I work out
of my shop exclusively its cords all the way.
I'll run a cord 50 yards before I'll buy another
cordless!

For JimD; The Bosch chuck, is it a specialized chuck for DIN drills, the ones that have dents for a ball bearing lock? I had the use of a Bosch hammerdrill with such a chuck and wonder if its being confused with a keyless Jacobs chuck that we have on most cordless drills.
Though I don't have a need to switch, I would think its possible to change to a keyed Jacobs chuck on any drill so long as the taper is the same, but only a tool doctor would know for sure.

I've got a DeWalt cordless drill with a keyless chuck that has served me quite well. I use it for most of my drilling and screwing needs unless it's something where a drill press is called for. However, there are times when the DeWalt is not up to the job, either because I need lots of torque or because the chuck is too small (or because the batteries are dead :D ). That's when I'm very glad that I've got a Porter-Cable, corded drill, with a 1/2" keyed chuck. There's no question but that cordless drills are convenient, however I still might first get a corded drill if I had neither, especially given what the cordless drills cost. One thing I don't like about cordless drills is the lower RPM's. To get the cleanest hole with small drill bits you really want higher RPM's than what any cordless drill I've seen can kick out.

Thanks for all the tips regarding drills.
I got the Dewalt 6 amp keyless chuck model at the orange store. 61 bucks with the tax. So far so good. I was able to drill into W oak using a 1" bit with no slippage of the chuck and bit. smile.gif Good enough for me. The drill has a built in bubble level as a guide for drilling plumb and horiziontal. :cool:
