I set my adjustment so I can hold the chuck by hand, and run the drill.

The ratcheting helps in the tightening.

Turn the drill to its slowest speed setting, turn the torque up, then hold the chuck firm while running it. On drill presses I abandoned keyless chucks altogether and haven’t looked back.

I’ve never had a problem with my cordless drill slipping on bits. One thing you might try is to grind a few facets on the shank for the jaws to grip on, maybe practice on a few cheap bits first. As for my drill press, I don’t think I’d want to use a keyless chuck on it, the torque is just to high and I doubt I’d get the jaws tight enough to keep it from slipping, since I’ve had that issue even with my keyed chuck.

Mine occasionally slips on me, typically when Im using a large forstner bit and try to remove too much too fast. My current solution is to just let up on the downward pressure and remove less. The issue with the slipping is that the forstner bits are perfectly smooth and round so there isn’t much to grab on to.

Do they sell drill bits that have the end as an hexagon shape (similar to driver bits)? That would almost certainly fix the slipping issue.

I use a keyless chuck on my drill press- and never looked back…. never have to deal with a key, open/close all 3 jaws… replacing a bit is a 1 sec, 1 hand operation

generally speaking slippage is only noticeable when using larger forstner bits. my forstner bits however have a hexagon shanks which prevents slippage, so I do not experience any at all.

I have had mixed results and I use both types on different drills. I use one with my lathe and that one is ok. I prefer a keyed chuck in the drillpress. but like Purplev says, he likes his. Maybe there is a difference in the quality of the different types?

I bought a keyless chuck for my hand drill and I’m gonna take it back to the shop and change it to keyed.

but then again, It could be just that brand of chuck

Thanks for the sugestions. I have three hand drills with keyless chucks and I don’t like them. I may change them out. some times they work ok but at the worst time they start slipping.

Easiest way is to get a good grip with both hands and tighten it if its giving yoiu trouble. I usually run it tight withthe drill but if it slips i get both hands on it and that takes care of it. some tiimes I wonder who the h* tightened it :-))

If you’re having a problem with slipping in a keyed chuck, I’ve found that if you rotate, & tighten with all 3 key holes, that it will hardly ever slip.

It’s kind of surprising, but you can actually tighten each one a little tighter.
