Ryobi Drill Press Chuck

[bg50]

Hello all,

I have been having a hard time identifying the right chuck for a used Ryobi drill press I picked up. It is a Ryobi DP102L it has 30 gear teeth on the chuck and my digital calipers read 0.23" (15/64 ???) for the diameter of the pilot hole. The chuck is stamped 1.5 - 13mm JT33. I have researched that to mean Jacobs Taper and I believe that is more about the mounting method than something relating to the chuck key. But not quite sure. I reached out to Ryobi and they could not help. I purchased a Ryobi multi-chuck key from Home Depot that they recommended but it does not engage all the way. The one that fits the best turns but the gears don't mesh enough to put any meaningful torque. The diameter of the pilot hole is fine (15/64ths) but the overall diameter of the gear head (about 9/16) is too small.

I have research the heck out of this. Any ideas I can try next? There has got to be an online resource that has the full specs for drill keys somewhere?

Thanks!

theres a chuck key that fits many import chucks, but I am not sure beyind that. I have bought various ones.

There are a wide variety of chuck key sizes.

I don’t know if that’s branded from Jacobs or Rohm(the two major chuck manufacturers)
Or whether it’s a generic Asian made chuck?
If it’s an Asian made chuck key then it’s probable a copy of one of the above manufacturers chicks, so the key would git if you can figure out which it is.

This is just a guess since the chuck brand and model number aren’t mentioned.
That chuck has the appearance of a Rohm chuck.
I don’t know if it is or not, but even if not a Rohm, it might be a clone of a Rohm chuck.
Rohm makes a chuck model 072819, 1-13mm capacity, J33 mount, external diameter 50mm.
Rohm specifies Rohm S3 type chuck key for this chuck.
The end pin diameter that fits in the three holes in the chuck for the S3 chuck key is specified as 8mm, for the S3 Chuck Key.

There’s also an S4 chuck key were the diameter is 9mm
And an S2A chick key were the diameter is 6mm.
