Jacobs 10mm (3/8") Capacity Hand-Tite Keyless Drill Chuck with 3/8-24 Mount 30354-1 Each

We have used Jacobs chucks probably several thousand times over the years, and they have never disappointed us. As expected, this chuck is well machined, threads smoothly, grips very well, and is easy to tighten. A good price point, too. This is one of those items that is exceedingly important when you're doing a job yet something you don't even think about - unless it malfunctions. We haven't had a Jacobs chuck malfunction yet. Very happy with this.

The Black&Decker LDX120 drill has awesome potential. I have put mine through all kinds of abuse and it still works great. The only problem is that the chuck is difficult to get it tight, and even when I get it as tight as I can, loosens up with moderate use. This chuck is the perfect solution. It is easy to tighten and holds bits without issue. HOW TO REMOVE THE OLD CHUCK AND INSTALL THE NEW ONE: You need aT20 torx wrench like this: Stanley 60-012 T20 Standard Torx Screwdriver. 1. stick the T20 wrench into the chuck opening and turn clockwise to loosen and remove the screw while holding the chuck with your other hand. It is on tight, so it will require some force to break it loose. 2. unscrew the old chuck turning it counter clockwise. 3. reverse the steps to install the new chuck. I added a little blue thread lock gel (vibratite) before putting the T20 screw back in.

Great replacement part for my Dewalt drill. Fit and worked as intended. Make sure this part number is compatible with your drill model number.

Tired of bits and drivers dropping out of your drill chuck when, say for instance you're on top of a ladder?? Then replace your key-less chuck with this one. Has a ratcheting tightening mechanism - don't know why I waited so long to look for something like this - so good, I'm buying two more for my other drills.

I purchased this chuck to replace a Jacob’s chuck w/ key on an old drill from the 90’s. I had no issues w/ installing the new chuck. So far it’s been operating just fine. My only gripe is how my original Jacob’s chuck is Made in the USA and this new one is made in China. We’ll see how this impacts its longevity, because the original 30yr old chuck still works just fine, but I wanted the ease of a keyless one. I also repair medical equipment and the “new” Jacob’s chucks that some of the equipment use are made in China now too. Unfortunately….

Does not fit the drills it claims to fit. My drill is a 3/8" DeWalt, a type specified on the product's packaging, but the threads on this chuck are much too small. Compare this chuck with my original (which looks identical except for the threads).

I replaced the original Chuck on my Black & Decker Drill Model LDX220 with this Jacobs Chuck. Wasn’t sure about quality or function, but I gave it a shot. Turns out this Jacobs Chuck was a good choice! Fit perfectly on the drill and gave me a much better grip on drill bits. Also Phillips, straight, Torx etc screw diving attachments. The black hand tightening front portion of the Chuck was a much better design than the original B&D Chuck. It allows you to get a GOOD grip on it so as to tighten it sufficiently to hold the bit/attachment in place. The original Chuck would always loosen up after several uses. All in All, good price, solid Chuck!

The chuck on my old DeWalt drill was getting worn out and difficult to open. This one (no center bolt) fit like a champ. No more struggling to open/close the chuck.

Easy to install, great product.

Great quality product that makes a lower quality drill work much better.

Good quality chuck and fitted the drill.

It is well made and easy to mount on a spindle of your choice. The jaws hold drill bits tightly but will not grip much under 1/16"

Ordered it was exactly what I needed and got it in the time I was told very happy with my service
