Drill Press Depth Stop

Sep 14, 2017 6 Replies

Am trying to find out what size the thread is for the depth stop on the Deta 18-900L Drill Press. Even Delta Machinery can't tell me. If anybody has the Delta 18-900L could you please tell me what size threads are on the set bolt #111, that the depth stop #11 fits on. Parts list forDelta 18-900l

Clarification? Are you saying that you actually have the #111 part and just want to know what sort of threads are on it so that, presumably, you can get a nut to fit it? My first choice would be to apply a thread gauge to the threads in question -- any machinist should have one or you might just drop in on your industrial fastener supplier with the part in hand and ask them to please measure it. I would measure my Delta DP but it uses a different (and inferior IMHO) depth stop system.

As does mine, it works but it's kinda chintzy.

No I do not have part 111 the set bolt. On my drill press, which I modified, I have a quick release stop that fits a 12x1.75 thread. I need another stop.If I knew the thread size on the Delta I would know if I can get one other Delta stop or if I need two stops and the set bolt.

I have an 18-900L at home. I;ll see if I can measure it tonight. You want the thread on the depth stop, itself, right?

Either, the internal thread of the stop nut or external thread of the set rod. Thanks,.

Mine is a 1/2-20 thread. Hope that helps.
