Is there a cross-slide vice that can actually bolt to the T-slots on my drill press?

Topic tags/keywords: question drill press vice attachment

Every drill press I have ever seen, including my disposable little HF 8” benchtop, has T-slots in the table and base supposedly useful for bolting on attachments such as a vice. However, I don’t seem to be able to find vices that will actually fit the spacing on those slots. What is the simple thing I am missing here? I understand building a platform as an adapter, but shouldn’t this stuff adhere to a standard that would make selling accessories to tool freaks easy?

The silence is deafening, and an answer.

I’ll give it a shot. Forgive me if this is something you already know. You put bolt heads in the T slot so you’ve got threaded posts sticking up out of the table. You slide those around so they line up with the mounting slot of your vice or whatever, then use a washer and nut to dog it down. The slots don’t have to be spaced the same between the table and the vise because you’ll be putting the bolts where the slots in the table cross the slots in the vise. I don’t have a picture of your devices, so maybe I’m missing part of your question. You can use 2 bolts in the same table slot to catch your vise in two places. If you clamp 2 flat rigid planes together at 2 points you’ve fully constrained the system and you don’t need to hit multiple slots in the table, but you can if that works.

I think Bob nailed it. Drill press manufacturers make drill press, and vise manufacturers make vises. Then, there are the manufacturers that make the hold down accessories. I was just looking at a set, but can’t remember what it’s called, but the price was 70+ dollars…....... Jerry (in Tucson)

Thanks, Bob. That is exactly the way I envision using the T slots. However, they just don’t line up with the vices I’ve looked at. I think this is one of those instances where a picture is worth more words than I know :)

I get about 4 1/8” from center to center on the slots. I have yet to find a vice I can arrange to fit that on this little drill press.

CB, I think all you need is a vise that has 2 mounting holes at least 4 1/8” apart. You don’t need to bolt all 4 corners down, just 2 diagonal corners is sufficient. There is no need for the vice to parallel the t-slots. If the vice holes/slots are closer together than 4 1/8”, just use some hold-downs in the slots to catch the base of the vise. Like Bob said, you only need 2 fixed points to fully constrain the vice. Any more than that is over-constraint and therefore redundant (not that it hurts anything in this case).

Barring all of that, depending on what your drilling, carpet tape has been known to do a fine job fixing a vise to my DP table for quick jobs :) NOTE though, don’t use tape if your using a cirlcle cutter or holesaw or anything else that might rip it loose.

That may be the answer. I wasn’t seeing that for some reason. Thanks.

Why not just make a sub base that will fit your DP?

Make an auxiliary base. Mount your vise to it. Mount the base to the drill press table with bolts and your existing T slots. :-)

Try mounting the vise cattywampus to the slots. The drill bit doesn’t care if the piece is 90 degrees to the table or not. Just turn the vise till 2 of the holes line up with the slots and clamp away.

If the vise slots don’t match the DP table, you can always use the old fashion method of clamping that machinists use all the time.

Any vise I have ever seen, has to be ADAPTED to fit the machine. A vise can be used on many different makes and sizes of machines, so there is no “standard”. To adapt, means to make a sub plate to mount the vise to. The sub plate is free to be moved around to be clamped where needed. A “C” clamp is adequate for fixing the sub plate to the table. A little imagination goes a long way.
