The invention of keyless drill chucks was a game-changer for making the best cordless drills easier to use. If I asked if you knew how to use a keyless drill chuck, you might be tempted to throw something at me for insulting your intelligence. But let’s hold off on that for right now, because we come across quite a few users who actually use it incorrectly.
Chuck History 101
If you’re not up to speed on your drill design history, many of us started with a keyed chuck. It’s that mysterious-looking thing that clips to the cord on your Dad’s old drill. When you insert it into a hole on the chuck, it creates a gear system that allows you to tighten or loosen it. Lose the key and you’re out of luck until you locate another one.
Keyless drill chucks came along and I think we all breathed a sigh of relief when we used them for the first time. Instead of using a key, all you have to do is twist the chuck until you feel it tighten down on your bit and start drilling. Most have a ratcheting action that you can feel as it tightens.
How to Use a Keyless Drill Chuck
Have you ever started drilling a hole or set a screw only for the bit to slip right out?
Manufacturers designed the locking mechanism on a keyless chuck to prevent this. We see a lot of folks in the field (and are sometimes guilty of it ourselves), just hold the chuck and press the trigger until the drill holds the bit in place. Some people have more success than others, but it doesn’t always engage the locking mechanism properly.
The Following Works on Ratcheting Chucks
You need to make sure you turn the chuck by hand until you feel it ratchet down.
So here how you use a keyless drill chuck more effectively:
- Hold your favorite drill or driver bit and turn the chuck until the teeth engage the bit (you can use the trigger to help if you prefer).
- Hand crank the chuck tighter until you feel it ratchet down. That’s it – simple!
Once you’re ratcheting the locking mechanism down, you should experience fewer instances of your bit slipping out. It might also reduce the amount of ribbing you get from your friends.
What About Non-Ratcheting Drill Chucks?
Non-ratcheting chucks certainly exist. These days, we find them mostly on older or entry-level tools. Cordless drills from no-name companies or products that attempt to truly cut as many corners as possible can use non-ratcheting chucks to trim costs. You also find them on older products made before the ubiquitization (I made that word up—like it?) of the ratcheting chuck.
The problem with non-ratcheting chucks is you never truly get a good bite on your bit. Even if the system does a good job holding the bit initially, it can loosen up as soon as you stop the drill.
What happens is that the action of the brake rapidly stopping the chuck causes it to loosen up. Many a Pro has lost an expensive spade bit or hole saw in an attic or down a wall cavity when a non-ratcheting chuck decides to loosen up and drop a bit.
