3/8" drill chucks

[Sean Garland]

My father would like to use larger bits in his 3/8" drill but needs a larger chuck opening. Does anyone make a 1/2" chuck that will fit a 3/8" drills mounting threads?

Sean Garland asks:

Jacobs among others. But can't he just locate bits with cut down shanks?

Chucks are available, check McMaster Carr or Grainger.

Often you can buy bits with the shank turned down to 3/8". If not, do you know anyone with a metal turning lathe? Takes but a few minutes to turn it down. Ed

Around here (Northern NJ) even Sears carries turned-down shanks in drill bits up to 1/2". Make sure the drill you're using has enough chutzpeh to drill that size hole in the material in question.

If you're talking wood, consider spade bits as a better alternative for fast hobbing.

If you're talking metal, consider whether or not you might be better served by buying or renting a beefier drill.

It's possible to burn up a small drill by using a bit that's too large for the motor. DAMHIKT.

We sell a lot of 1/2" keyless chucks (Mostly Makita (Jacobs)) that have the standard tread for the 3/8" drills spindles, They provide the larger capacity but you have to remember the spindle is small & easy to snap if you use the drill under extreme 1/2" capacities. After all a drill is only as good as its spindle & gear strength when it comes to heavy work.

For about $35 Canadian or $28US most our customers are very pleased with the upgraded chucks.

I put one of these on one of my corded drills and am quite happy with it. I would have prefered a keyless, but HF did not have one and for $5 ....
