Been drilling holes in discs and other round type objects that are
around 1". The things like to spin on me. Tried some suggestions here,
ie, slowing down the motor speed, which helped a lot, and carpet tape,
which just spun with the object. On some of the objects I can get a pair
of pliers around the object to hold it. Pliers mare the surface of the
object. I tried tape wrapped around the pliers which worked a little but
still some maring. I'm going to try cotton balls then tape, but does
anyone know if there's some sort of plier type gripping tool that's
available? I tried looking on google but if there is, I don't know what
it's called.
Forgot about those things. They would work, but how easy and quickly can
objects be removed from them. Wonder if there's something like pliers
that would be easy and quick to release the piece and grab the next?

Well after the third recommendation for a V block I'll have to give it a
try here in a little while. I've seen that used before but didn't think
of it. Must want a new tool or something. :)

ViseGrip makes a chain wrench which will wrap around a cylindrical
object, then tighten down with the cam action used by all vise-grip
pliers. The chain is free on one end to wrap around the object, then
secured in a pair of hooks. This would require something to contain
the plier handles to keem THEM from rotating.
I have an old pipe vise which already comes with the stepped V-blocks
as standard equipment. One side of the vise opens to roll in the pipe,
then closes and locks with a hook type catch. A threaded shaft and
T-handle cause the V-blocks to close on the object. The base of the
vise has 4 mounting holes to permit it to be mounted to a flat surface
in any position. Mine is bolted to a piece of 2x6 lumber which I clamp
to a sawhorse when in use.
Both of these solutions involve metal contact to the work piece and
are capable of crushing the work with excessive force.

Tom ,
I am going to a few things and hope I don't make and "ASS of U and ME"
1 You are drilling the face of the discs
2 You are using a dill press of some kind.
Try making a jig on a piece of plywood. Two strips of wood at a 45d angle to
each other with snadpaper on the edge of each.
If you need more holding power use a third pice of wood that fits the angle
and put sand paper on that and use a quick clamp to hold that against the
disc to be drilled.

What are the disks made of? How thick are the discs? How large
diameter is the hole? What type of drill bit? What type of drill?
If you are working on a drill press on wooden or plastic discs that are
at least 1/4 " thick with good bits; I would consider making a V block
fastened to the DP table. Line the insides of the V with sand paper. I
think the pressure of your thumb pushing the disk into the sandpaper on
the V would be more than sufficient to prevent turning. If not, I
would work out a cam of some type to increase the pressure.
Keep the whole world singing. . .

<snip>
Depending on how thick the discs are, but will suggest the following:
Take a piece of stock, I like to use Birch cabinet plywood, about 50%-75% as
thick as the disc, and bore a hole slightly larger than the disc.
Locate this piece of stock so that the hole is centered under the drill bit
and attach to the drill press table.
Take a 2nd piece of stock and clamp it, using quick release clamps, over the
first piece of stock thus clamping the disc in place.
Drill holes as required, then get beer.
You will have earned it<G>.

LOML bought me one that is called "Grip Wrench". Probably available at
Borgs and HF. Works well for what it's supposed to do which is what you
need.

So go buy yourself a fancy new drill press vise that has V-shaped jaws.
I've seen'em somewhere.
Not as cool as that jig I drew with ASCII art though.

And if you has to very many, it will take forever. If he doesn't have many
to do, it would take more time to do this than it is worth.
Softjaws. Wooden jaws in a vise. Shape jaws to fit parts. 1/2 turn of the
screw to clamp or remove parts. Fast, easy.

Do a search for "strap wrench".
Recent post described a 14" strip of wood with proper sized hole near
one end and a sawkerf from the long dimension to the hole. Insert
disk to be drilled and squeeze the kerf closed, dril, release and
repeat.
