Makita 763198-1 Keyless Chuck , Grey

Works fine, but takes time to figure out how to release a drill bit. Quality product, as you would expect from Makita.

I own three of these for the three impact drills that I own. I am a professional furniture restorer and repair man. This chuck allows me to use my impact drill like a regular drill. It makes the drill a little heavy but it works well for me. My brother and father both saw this chuck and insisted that I get one for them. I have read in some of the reviews that this chuck has one inherent issue. There are times when you will insert a screwdriver (or maybe other type) bit and it will get jammed/locked up inside of the chuck. I have experienced this issue as well. I noticed that the few times it happened to me, that the actual chuck will unscrew itself from the shaft ( which is the part the drill holds onto) it will get unthreaded from the chuck (the part that grips the bit) while the bit stays stuck in the chuck. I was usually able to get the bit to dislodge itself but there was once I was not able to. So I cleaned the threads of the chuck stem and the threads inside of the chuck head with denatured alcohol. I then mixed J-B Weld 8281 Professional Steel Reinforced Epoxy and applied a little to the threads and screwed the chuck head back into the bit stem. I cleaned up any epoxy that oozed out from between the top of the bit stem and the bottom of the chuck with the denatured alcohol. I left it for 24 hrs. I then held onto the chuck as usual and reversed the drill and the chuck opened and out came the jammed bit. Now this never happens anymore with this particular chuck. I've seen other reviews where something similar to what I suggest was done and it worked for them. I'm waiting for it to happen to the other chucks that I have and I will do the same for them. If you have a jammed bit try this method. Make sure you use J-B Weld 8281 Professional Size Steel Reinforced Epoxy since it has the strongest tensile strength (5020 PSI) of all of the epoxies that I could find and remember clean the threads with denatured alcohol until they are clean and free of any oil and only use a little of the JB Weld. https://www.amazon.com/gp/product/B014OVHAOY/ref=ppx_od_dt_b_asin_image_s00?ie=UTF8&th=1

I am bewildered by the negative reviews. If you expect an impact driver to drill perfect holes, you’re delusional, regardless of the attachment. If you’re a homeowner and only want to buy one tool and have it do double duty, you have to be willing to accept the resulting compromise. A drill can drive fasteners, but never as well as an impact driver. An impact driver with this attachment can drill holes, but never as well as a drill. If you’re unwilling to accept one of those compromises, then your other option is to pay for both tools. If you’re a tradesman, as I am, and if you thought this could replace your drill... I’m not sure if I should laugh at you or weep for you. This sits in the back of one of the drawers in my tool chest, so that if - for whatever reason - my drill becomes inoperative, I have something else to get me by until I can repair or replace my drill. It isn’t great, but for getting me through a pinch, it’s a perfect compromise between having redundancy and flexibility in my toolset, and making my hard-earned nickels stretch as far as possible. For all the individuals getting their bits stuck... Loctite. Clean the threads, put red Loctite on them, tighten down securely, and let it cure. Then reattempt removal of your bit. Or, if you know someone who can weld, offer them a beer in fair exchange for making the driver shank permanently installed. As for the tool itself and its tolerances, it is absolutely worth the price. As a backup, I’d buy a decent corded or air powered drill instead of spending $50 on this. At $20 to $25, it’s a great deal. All metal construction, appears to be entirely steel, body turned on a lathe, etc., made in Japan with all of their famous attention to detail. Far and away better than the cheap Chinese chucks. Is it a top-of-the-line Albrecht or Rohm? No, but it isn’t anywhere near those prices, either. Is it even as good as my *old* Jacobs chuck on my much-abused Hitachi drill? No, but it is still satisfactory for a backup. Why not five stars? Again, it isn’t an Albrecht or a Rohm. I only give five for really first-class, top-notch stuff, regardless of price. This is great, and fairly priced, and deserves solid four stars.

This works good in my Milwaukee impact. Should of bought a Makita because Milwaukee dose not make one.

Works as intended

It has the Makita name, but sorely lacks Makita quality. I purchased this to go with a Lithium Ion 1/4" driver, and thought that every other item I have owned from Makita is still working, and this must be good. I was wrong it drops drill bit so often that you get in the habit of re-tightening after each time you let off the trigger. The problem being it is metal and heavy, and the new drivers have an electric brake, so when trigger is released driver comes to a sudden stop, but chuck adjustment ring keeps spinning until it hits other side and loosens jaws. This happens every time, I cannot begin to calculate how many times I try to use driver again, only to have bit fall to ground or bottom of something. In addition to this rather annoying feature, chuck started to hang up, and is almost impossible to take apart. When i finally did get apart, I found that the teeth on one of the jaws had sheared, and were stuck inside gumming up the works. I would like to throw this through Makita's front window, but I do not live anywhere near their offices. I will instead use as a paperweight, and no longer assume that if it has Makita's name on it, it must be good

Great attachment

This chuck will not stay in my Makita drill. I'm not sure why. I"ve had my neighbor check it out and he too is puzzled. By the time I found out , it was too late to return

Works great with small bits. Recommended

Seems to be very well build and does what it's supposed to do. Reading some of the one-star reviews here where people have issues with bit release when stopping, I wonder if they hadn't realised that pushing the collar of the chuck toward the bit prevents the tightening/loosening mechanism from engaging? I.e. the centre of the chuck spins independently.
