How to drill a hole in a hose clamp

I'm rigging something up where I need to drill a 1/4" hole in a hose clamp. It's not that I haven't done this before, but, the stainless can be hard to drill and when the bit grabs right before you break through, it can be more excitement than I need in my life.

Anybody got any clever ideas ?

Put the hose clamp on a dowel or pvc pipe and drill with a drill press V-block and fence.
If you don't have a drill press, clamp your work to your bench.

Do not put it on anything round!

Flatten it out when you drill it! First off, the drill will skate off the surface if it's on something round. Second, it will attempt to cut different amounts of metal and grab. It it's pressed flat, it's much easier to drill, but it still may grab and rotate on the spinning bit ... which will case it to cut like a weed whip. For the inexperienced, grinding is the best and safest option.

If it were me, I'd use a drill press vise with a thin wood backer underneath of a slightly narrower thickness so the vise will hold it securely. A center punch dimple will help locate the drill bit. Drilling stainless requires constant feed pressure and a sharp bit Titainium or Cobalt. Watch out when retracting the bit upwards because it may lift the clamp out of the vise, causing it to spin. This is a dangerous operation, so be cautious.

The answer to your question will only be as detailed and specific as the question is detailed and specific. Good questions also include a sketch or a photo that illustrates your issue. (:< D)

First I'm assuming that the clamp is something similar to a "Stant" clamp or radiator hose clamps from way back.
Second I'm assuming that you need to attach the clamp to something with a screw.

I wouldn't drill but rather a chisel to chop out some of threads (Slots). Then use a washer head screw to attach the clamp.

Flatten it out and use a step drill. It won't grab badly when it punches through and it will also deburr the hole edge. Turn it over and touch the next size up to deburr the opposite side as well.

Anyone who has yet to own a couple of step drills should consider adding them to their tool list. They are quite versatile.
