Drill press chuck key size?

[jamesm113]

Picked up a drill press off craigslist, Central Machinery 44506, but it did not come with a chuck key. Chuck says 1-13mm J33.

Trying to figure out what chuck key will work for me. I measured a ~1/4" chuck pilot hole and I counted 30 teeth on the chuck

Try the chuck key from your half inch drill. I bet that will work.

Probably be an S3 size key.

Sorry for the delay, I don't seem to be getting notifications for this thread.

I don't have a half inch drill or any chuck keys laying around. I ordered a 1/4" pilot hole chuck key (DeWalt DW2304), but it did not fit. I can fit a 15/64" drill bit through the pilot hole, but not a 1/4" drill bit.

What is an S3 size key?

whenever I need a chuck key I have better luck taking the tool or the chuck in to my local ma & pa hardware store or tool store.

^ This. And if you can't bring the tool to the store, buy 1 of each size and then return the rest. That's what I had to do with my floor-model drill press. Bought 3 different sizes, returned the 2 that didn't work.

The 1-13mm is the capacity of the chuck (half inch in English).

J33 is the size of the female taper on the chuck, that accepts the arbor. (Jacobs Taper 33). All fairly standard.

What you need to know is the make / model of the chuck. If it says, for example, ”Jacobs” and a model number, you can get a new key easily (MSC if you haven’t got anywhere local).

If there’s no name then it might be a copy of a Jacobs or Rohm and the same key might fit. If not, go with the suggestions above and take it into a shop if you can.

I brought the press into a tool store. The best fitting one was for a 3/8" chuck & 15/64" pilot, Milwaukee part number 48-66-3240. They also had a Jacobs one for 3/8" chucks / 15/64" pilots that fit as well. Think the Jacobs was part number #30825.

Thanks for the help everyone

I buy every loose key I find at garage and estate sales. Seems I always have 1 that fits. If it’s my only, and I have more than one chuck, I will buy a second key in case the tool needs to leave the house.

Moral of the story. Whenever you see misc. chuck keys at a garage sale buy them. They're usually cheap and it's nice to have a large selection of them on hand.
