    Need to drill 1/4" inch (??) hole into small chrome tube --- only through one side.

    Saw lots of online suggestions but what if I took a worm gear hose clamp and fastened around tube and then slip the bit between the "slit" in the clamp to hold bit on place as I start to drill?

    Thin wall tube. Not "fragile" but no centerpunch

    That tube will bounce around like a mexican jumping bean on a pogo stick. What's inside diameter? Can you get a dowel rod to match and put inside so you can clamp it down without distorting the tube? No matter what, I still think a punch to start the hole is the best idea. Use a drill press, not a handheld drill, and anchor the tube so it can't bounce around.

    That kind of thinking is so yesterday and outdated!

    I'd use a Drenel with a burr tip to grind a depression in the place where you want to drill the hole and drill it out with a clean cutting step bit like a Unibit.
    A Unibit will cut a clean round hole in thin metal,
