Hey LJs,

Do most of you use a 1/8 – 5/8” chuck in your press and leave it alone? Or do you use 2?

I’m setting up a PM2800b and replacing the chuck, but I’m not sure if I need anything over ½” for most woodworking projects. Thinking cabinet door hinge recesses, and normal hobby/home-built furniture.

Mine goes to 5/8” but rarely need that big. I think more important is small bits. I bought a keyless one that goes down to 1/32” and was about $60 on Amazon.

High quality chucks will accept numbered bits. For lower quality chucks, a second, smaller chuck will be needed.

I have the same drill press, I replaced it with LLAMBRICH USA
Keyless High Torque Drill Chuck 0.512” Cap., 2MT Mount Size, Steel
This is an expensive chuck , but will hold small bits and never slips, it is so smooth. 1/2 size has been fine for all my woodworking needs.

Never needed larger than 1/2, so I got a decent key chuck that gets real small.

I replaced my 1/2” (which had a fairly amount of runout) with a new one, and sized up to 5/8”. The 5/8” chuck still goes down to 1/16” which is small enough for the stuff I do. I did eventually add a chuck for my lathe and it uses the same MT…so if I ever need something smaller I have it…but that hasn’t happened. Onwe thing I learned was that adding the 1/8” can mean a lot more than you bargained for. Here’s a pic of the 2 chucks…you can guess which is the 5/8”.

Let me correct an error in my statement above. The smaller chuck is a 5/8”, and the larger one is 3/4” (still goes down to 1/16”) I remembered the new being 1/8” larger, but forgot the starting point was 5/8”. Senior moment I guess.

I don’t worry about the big size much but a chuck the will not close all the way so it will take very small bits, is worthless to me… I know you can get chucks to put in you chuck to handle the tiny bits,,, but I have not had one of those mini chucks that did not wobble all over… I use lots of tiny bits as a hobbyist…

You really don’t need a chuck that opens to 5/8 since you can’t get drills with a straight shank over 1/2”. Usually anything over 1/2” will have a reduced shank (Silver and Deming) or have a taper shank.

Thanks, Mr. Ron, that is what I was expecting.

Mribelin – I was trying to get that same Llambrich and the order was canceled for lack of stock. I’ve not been able to get a ½ or 5/8 from Llambrich. I agree with what all/most of you are saying, ½ is about as big as a drill bit as we come across. I wanted to confirm that before overspending on a chuck to that size.

Ended up getting an Albrecht because it was in stock and I’m guessing I won’t need another for a very long time. Dang thing is gorgeous but expensive.
