View Full Version : Proper way to attach a vise to a drill press?

This may be a dumb question, but here goes:

What's the proper way to attach a vice to a drill press table? I scored a tabletop drill similar to this one from a college votech shop
http://www.metrocast.net/~mnorman/images/owwm/sprunger/sprunger_dp16.jpg

and I picked up a vice similar to this one.

But I'm 2nd guessing how to attach it properly. I can bolt it down, but I have to offset my table in order to get the center of the vice on center with my drill bit.

Is this normal?

(if you can't tell, this is my first press/vice combo)

Cheers!
Mike

I can't recall ever bolting down a vise on a drill press table, clamps or nothing but make sure what ever is in the vice, if large, is up against the column (or clamp), watched a guys belly get torn open, wasn't pretty.

Typically the vise is bolted with a bolt and t-nut under the table. But like Mickey said the vise is not typically bolted down unless you are doing some production work where you want repeatable position in many parts. A c-clamp may be used or a regular bolt through the table to provide a bump stop to keep the vise from spinning if the torque on the vise is more than the operator can hold. No one way to do this, each setup requires its own solution.

A true drill press vise will have a center bolt with a shoulder which matches the hole in the center of the table. Often, this bolt is on a rotary table, with the vise bolted to it. The vise is removable if some specialized setup requires an off-center vise mounting without using the rotary table.

C-clamp it is!

Thanks guys.

I use a 1/2-13 bolt&nut and some washers. The 1/2 is overkill as far as strength, but it fits the slots in the vise nicely and that makes for faster setup.

bolt it to the table
you see the slots on the side of the vise, those are for adjustment.
you can also offset or rotate the table for added adjustment

I have seen a bit grab and spin the object and the drill press vise because it was not bolted down. now you have a bigger chunk of metal flopping around that can really hurt you or the machine

I don't usually bother to clamp it (Jed). Just turn it so that the long end of the vice rests against the column to resist the torque.

Many times when using a drill press vise, it is useful to allow the drill to find the center of the pilot hole or center punch prick. Bolting or clamping the vise to the table makes this impossible.

Instead, consider installing a bolt and nut with a number of washers though the left side slot on the table. Run your vise up against this "stop" when drilling and hold it there. Doing so will prevent the vise from spinning should the drill grab, yet allow the vise to "float" on the table.

Use two setups on my DP. First vise slides on a track, second can be clamped or can swing against a bolt in the table.

Second vise is a kid's shop project (from across the street) that his old man tossed out after he moved, I added the angle brackets. Guess he didn't realize what a good project it really was.

I use one of these to clamp the vise down.

Our machine shop in college had these vises attached to the drill presses:

They hold onto the part and keep it flat against the table, but won't let it grab and spin out of your grip. I really wish there were a less expensive version, I'd love to have one for my home shop.

Ooooooooo! I like that!

They're also kind enough to provide a dimensioned drawing:

Looks like a shop project in the making. :bounce:

We got something similar to that after the idiot tore open his stomach, wouldn't have helped in his case (hole saw and sheet metal) but they got one just the same.

I like lilredex's vise on the slide table.

I've been tempted to draw one up and have it made, maybe I should get off my butt and do it :)

I use several drill press clamps to hold down work and sometimes a vise. If I have something on the press that I can't clamp down I position the work so that a part that sticks out is up agains the left side of the pole. That way if the bit fetches up it wont spin the work around and hurt you since it is already against the pole.

Here is a photo of a drill press clamp.

you need a bigger vise

or bolt that vise with counter sunk bolts to a 1/4" piece of plate then bolt plate to your table

if you don't bolt what material your drilling to your press table please count your fingers before and after :) take pictures :lol_hitti

I took some 3/8 bolts and welded on some large (2 inch) 1/4 thick washers. I use those to hold the vise down. My vise has the "teeth" on the side so the washers allow for greater clamping.

I just use wing nuts on the bottom to make things a little faster.

The problem with the drill press vises that I have seen are that the one jaw is fixed while the other adjusts. Unless you only drill the same size stock, the bit center and stock center change. Do they make a vise where both jaws adjust so you can always center or intentionally offset the stock?

you could get a 2 way cross slide vise if your press table doesn't turn

not sure if the make new press vise that has the sliding jaw my old one does

I just have mine on top of my magchuck. When that 3/8" alan wrench is turned 180 degrees....that magnet wont let the vise on top move anywhere! They are great. I can move the vise or anything metal Im drilling into the spot I want it to be and its locked. Its amazingly powerful magnet.

With a true drill-press vise mounted off-center on a rotary table, between swinging the drill press table and the vise rotary table, the stock can usually be centered under the drill. Then, both are tightened to lock them in place.

A machinist clamp set is what I use to hold down the vise or whatever else I am trying to hold steady while drilling.
