Drill Chucks

[SpecialtyTool]

Do you use any drill chucks? Seems like most of my setup time is looking for collets. There are a lot of nice chucks designed for CNC that aren't much more than a whole set of collets.

Drill chucks on a CNC, almost never anymore.

 

I kept mine handy for an indicator.

 

Using carbide drills with steel jaws will wear out a chuck quick

I think it depends on what type of work you do, and how the shop is tooled up. If you are doing a lot of drilling with different size holes I find it faster to use drill chucks.

 

All the shops I've worked in use HSS Drills, so what UParis said didn't apply.

Most drill chucks designed for cnc machines that I have looked at have diamond coated teeth. Albrecht are the ones that Im leaning toward. I just wonder about accuracy with them.

I have 4 drill chucks in my arsenal that I use all the time for HSS drills.

All Jacobs chucks of course, the 3/4" capacity chuck always has my edge finder in it, the other 3 are for small hss drills.

Carbide drills I always use a collet.

Using a tool presetter, chucks were just never a first choice.

 

I supposed it depends what you're doing and how you're doing it.

I work in a job shop,no production here, everyday is different.

The only time I'd better see a drill chuck in one of our CNCs is if it has an indicator or edge finder in it; we use strictly ER collet chucks for toolholding.

You like those keyless chucks? I've never had a good experience with them.

[MACHINEMASTERG]

sure there good for basic drilling .

they come with a spanner wrench if you want to tighten them up some more

but ive never had a slipping issue with them )

we all know why not to use a chuck, but drill chucks are very handy and quick. I like the type that use a allen wrench to open/close via a worm gear. Not quite as quick as a keyless chucks, but they offer a more positive grip. I'd rather see a quality cnc drill chuck than a tool in the wrong size collet.
