I have a new Makita drill I just got.
Its a cordless with hand tighten chuck.
Everytime I use it with a screwdriver or drill the attachment falls out of the chuck?
Anyone know why it does that or how to stop it?
It makes it almost useless.
Seriously though, you really need to grab the chuck collar and pull the trigger so that the snap gets the chuck TIGHT. Most keyless chucks on cordless drills are designed for light duty work. I had the same problem and finally removed and tossed the chuck and replaced it with a keyed chuck.
When you say "the attachment" are you referring to the chuck falling off the end of the drill? If so, the chuck may be mounted by means of a morse taper. For this to be successful you must have both tapers absolutly clean and oil free. Then tap the chuck onto the taper stub. Try that and see if it solves your problem.
FYI, Makita and Porter Cable are the only power tools made in the USA.
Makita is Japanese owned but made in the US.
Porter Cable is US owned and made in the US.
I did some extensive searching on this a few months ago and this is what I found...
If it one of those white makita lithium-ion drills, put the drill in 2nd gear, grab the chuck tightener as hard as you can, and just torque it down using the drills own motor.

Yep, Porter Cable makes good stuff, I own two of their corded drills. Made in the USA.
Makita is Japanese owned and SOME of their tools are made in the US. I have a 3/8 cordless drill. The drill and charger are made in Tiwan, the LiOn batteries are made in Mexico. I also have a Makita cordless circular saw. The saw is made in Tiwan. The carbide blade is "Made in Japan, assembled in the Phillipines". Makita has final assembly factories all over the world and one of their largest part production facilities is in Jiangsu, China.
Maybe it's just me but I feel that if you're going to brag that your product is "Made in the USA" it should mean just that, not that it was packaged in the USA from parts produced all over the world.
I drive a Ford pickup that's made in Mexico from components produced all over the world. However most people would say that I'm driving an American truck.
Not to hijack this thread but I agree with you pupnDuck. Even though many American items are manufactured elsewhere, the profits stay here and benefit the US economy.
When you buy something made by a foreign company, you are very likely funding their government.
The USA make as good a car as anyone else and cheaper too. If you visit any other country in the world the most popular car on the road is whatever is manufactured in that country. Why can't we do the same?
If the chuck is worn out, you can replace that by itself. If you open the chuck all the way, you should see a phillips head screw all the way down. This screw has reverse threads- Turn it left to remove, then grab the chuck tight, and run the drill backwards to remove it. You may need to chuck a tool in it to get leverage if it's really tight. When I need that, I use a 90º allen wrench, and smack it with the heel of my hand to break it loose.
Your drill should have 10mm mount threads, you can get keyed and keyless chucks for it.
Its brand new been used 10 times.
Paid over $200 for it or Id chuck it.
When I say the attachment falls out I mean the drill , screwdriver or whatever I have in it falls out.
Ive tightened it using the drills motor and holding the chuck.
As soon as I reverse the bit falls out.
I'm guessing you have more trouble with driver bits than with drill bits, The jaws of any drill chuck are extremely hard. The shank of most drill bits are fairly soft. It's that relationship that allows the chuck to hold the drill bit. However, most driver bits and especialy screw driver bits are hardened through their entire length. Not a whole lot of friction there between the chuck and the bit. Yeah, I know the drill is designed to work in both forward and reverse.
You can exchange it. Maybe the chuck is defective. Or you can replace the chuck with a keyed version by spending even more money. Over the years I've had a number of Makita cordless drills with keyed chucks and never had a problem until I got my first keyless chuck. Fortunately, I hadn't tossed my last Makita yet (I stripped out the clutch gears) so I swapped chucks.
I have a 1/2" industrial B&D that's about 30years old, and it doesn't drop bits on it's own. That thing is so torquey it'll rip right out of your hands if you're not careful.
The chuck is defective on yours.
It holds them but the torque of going back and forward seems to loosen the chuck.
Im starting to think maybe its to torquey?
I sometimes see my 18vlt loosen in reverse & drop a bit if I don't do a 2-handed manual tighten down step after I've run it tight holding the chuck. If I'm trying to back out a 3 inch deck screw or lag & all I've done is tighten it by motor alone it'll drop it every time.
But I love my 18 vlt makita, especially since I got 2 new batteries for early Christmas present.
