1/2" bits in a 3/8" chuck?

[Jay Pique]

Is there any sort of 1/2" chuck that you can chuck into a 3/8" chuck so you can use half inch drill bits with your 3/8" drill?

You can remove your 3/8 chuck and buy a 1/2 that fits the same thread pattern. A good hardware store should have ii.

You could also buy the same 1/2 chuck and install it on a bolt and saw off the head to chuck in your 3/8. The 3/8 spindle should be a 3/8-24 thread. The 1/2 spindle should be a 1/2-20. They also make 1/2 chuck with a 3/8-24 thread.

For the price of a 1/2" chuck and the trouble installing it, you could buy a new 1/2" drill.

There are 1/2" drills which are stepped down to fit 3/8" chucks. I've had a Craftsman set from the mid 70's with just that on the 1/2 drill. Try

or for specialty items such as this.

Probably. Somewhere. I wouldn't buy one, I'd spend my money on a drill with a 1/2" chuck instead.

Turn down the bits to 3/8" or buy a 1/2" drill.

You KNOW the answer, JP... you're just looking for confirmation..

YES, you should buy a nice 1/2 drill-driver and at least one extra battery and several accessories....

You're welcome, glad to support a fellow tool junkie..

You can buy a Makita 9/16" hammer drill, keyless (Makita HP1501K) for about 69.00 on line. I got one free with my LS1013 SCMS, (I wouldn't have bought one 'cuz I already had a 1/2" Milwaukee, but what the hey...it was free.) and now it is the most used drill in my shop. (The cordless ones seem to always hide in boxes or bags somewhere.... the cord actually serves as a locator as well.) Lots of balls, will run at high speeds and just a nice grip too.

I've got a 1/2" drill. What I was thinking of doing was using a drill guide like LV et al sell. But they only have 3/8" chucks on them. The 3/4" LV brad point bit I have is 1/2" shanked, and that's the one I'd wanted to use. It's not a big deal, I just used a 3/4" forstner bit instead.

Great! You're all set then. I misuderstood your question.

Just buy the bit that will fit. I mount up to 1/2" bits in my 3/8" chuck all the time. Many bits larger than 3/8" are made with 3/8" shanks.
