Is my makita drill broken?

Hello, 

so i recently bought a cordless makita combo kit ( impact driver and drill driver)

and while i was using the drill driver at work i noticed something odd, when tightening drill bits the chuck seems to click after it has been tightened? Is this normal or is there something wrong? Sometimes it would click/spin quarter turn multiple times after being fully tightened. There has been times were the drill bits have fallen out(chuck loosened by its self) Would appreciate any help

The clicking is normal is normal on a ratcheting chuck. Higher end drills have that so you have better grip on the bits

Welcome to the forum Beens! Sounds like a ratcheting chuck to me. As you continue to tighten the chuck continues to ratchet tightly and keeps that’s drill bit in place!

Sounds normal to me welcome to the forum 

Thanks for the help, and fast reply!

This.

Also if you’re using bits with flats that you tighten in the chuck, just to make sure the chuck is tightening on the flats, pretty obvious stuff, but I’ve seen people not check that simple detail.

And welcome aboard

Well this is a coincidence, I just walked out to the shop at my in-laws, and this is how I found the drill that my brother in law was using:. 

He’s a little iffy when it comes to these things but perfect example of people not noticing these things

I think you need to hit him fingers with hammer – it will help 😀

That’s why you never tighten a chuck by hand.  Always hold the chuck and run the drill so it catches on the flats.

So you know it is centered, then I make sure the jaws are on the flats. But then I give a little extra twist by hand once the bit is in place to tighten down a little more

I’ve noticed the same problem. It’s not right, I’ve sent 2 top of the line makia drills back because of this. I then went to a tool store to try out their stock. While the sales assistant couldn’t get the chucks to crunch and then slip I was able to do it to all the Makita’s but not the DeWalt’s, Milwaukee’s or even the Bosch drills. I love the Makita products and have the 18-volt battery range. However this is really pissing me off. I took a part one of the drills to investigate what was actually happening as it sounds like teeth slipping. The part that locks up and should grab indefinitely is a bearing type freewheel which locks up when they chuck is held or driven by hand. These type of three wheels are used in many applications with great success however I suspect Makita have got some of the dimensions ever so slightly wrong. The crunchy sound you hear when it slips round under very tight conditions is actually the frewheel slipping round it’s race. One good thing to take away here is the gearboxes are more than enough and it’s not teeth slipping as it feels like. I’m going to try and work on this free will an experiment with some slightly different dimensions.. Most of the manufacturers seem to have solved this is a shame Makita haven’t.
