My Bosch 18v 1/2" drill seems to be on its last leg, so I'll be looking for a replacement. Just wondering which brand has really good chucks on their cordless drills? I'm not married to any brand or battery platform.
The high end Dewalt and Makitas have good chucks. I have seen a number of Dewalt drill with Jacobs chucks; Makita with Europeon brand (Czech?). Milwaukee chucks are terrible; Rohm makes a great replacement for the 9/16" arbor found on Gen 2 and later drills.
Ultimately, it really doesn't matter what drill you buy. If you don't like the chuck, it can be replaced with an aftermarket; most arbors are 1/2"-20.
I use Milwaukee and install Rohm chucks.






This seems highly unlikely.I thought about upgrading my current Bosch, but the chuck isn't removable. The whole gearbox unit needs to be replaced, and you get the same plastic chuck with it.
I’m totally in Milwaukee cordless toolsIf you are having trouble with your chuck, give the insides a few squirts of WD-40.
That's because it's a crappy chuck.I’m totally in Milwaukee cordless tools
What I have found with my drills is when you are in high speed mode drilling and pulling out if you release the drill throttle quickly the drill stops immediately and loosens the chuck. Sometimes it’s on the second or third hole
I’ve learned now to release the trigger slowly to avoid the loosening of the bit in the chuck.
What model number? Just looked at 8 or so on ereplacementparts, and those with a chuck, not 1/4” hex, all had separate part ## for the chuck.I thought about upgrading my current Bosch, but the chuck isn't removable.

Milwaukee went though a phase where they had truly poor chucks. I have to think it was some MBA bean-counter who demanded fewer parts across their product lines and pushed a cheap one from the lower product lines into the higher product lines. They rightfully got a lot of **** for it.Everyone talks about how bad the Milwaukee chucks are but in my experience the Dewalt chucks, even the metal ones aren’t all that great either. I can’t begin to remember all the bits I’ve dropped because the chuck loosened while drilling. Even more annoying when it’s a hole saw you drop through the hole you just drilled in the floor.
Honestly can’t say I’ve had a good drill chuck since I retired my corded Dewalt with the Jacob’s keyed chuck on it.

That's only true if you're getting a pretty cheap drill. They're about half the cost of most 'better' drills from the various colors.Those Rohm chucks seem to be quite expensive. They cost about as much as a bare drill without battery.


Chucks that repeatedly click when being tightened are usually ratcheting chucks.I hate the chuck on my Milwaukee FUEL 2706-20 it holds bits fine but sometimes is a bear to open it back up. I don't actually use the drill all that often I generally use the impact drivers but I keep a pair of channel locks handy in case I need it.
I looked online and it seems the required chuck for this drill is 9/16-18. Can anybody confirm that this is right?
Would this be a good replacement? The chuck on the Milwaukee is metal and "clicks" while tightening. It seems like decent quality not sure if I broke it or not. Haven't heard of Rohm before this thread but sounds like they're decent chucks so willing to give it a shot.

When I first looked for Rohm chucks the ones I found were around $140. I looked again and see there are a lot of less expensive chucks.That's only true if you're getting a pretty cheap drill. They're about half the cost of most 'better' drills from the various colors.
Don't be a jackass.Ive had great luck with my Milwaulkee chuck on my Gen2 (?) hammerdrill. Worst was my old Dewalt XRP that actually was recalled and had a new and improved chuck installed, much better.
You guys know how to tighten a ratcheting chuck, right?
What do you mean? Dont be a ****.Don't be a jackass.
I usually pay around $35-40 for my Rohm chucks. I have bought from Amazon (new in the box) and from eBay (DeWalt original equipment).When I first looked for Rohm chucks the ones I found were around $140. I looked again and see there are a lot of less expensive chucks.
When I looked for Rohm chucks a second time I saw that many of them are $40 to $60. I am not sure why I saw a bunch for around $140 to $150 the first time.I usually pay around $35-40 for my Rohm chucks. I have bought from Amazon (new in the box) and from eBay (DeWalt original equipment).
Rohm manufactures (or at least sells) drill chucks ranging from basic steel keyed drill chucks, to Basic inexpensive plastic sleeved keyless chucks, to high precision ball bearing chicks, and high precision keyless chucks.When I looked for Rohm chucks a second time I saw that many of them are $40 to $60.
