I did not go far enough in my information.
I know what I was looking for. You did not. This should help.

I went to
go to - Chucks and machine accessories.
Then click on - Drill Chucks Key type
scroll down to bottom to Sensitive Drill Feed
Click on picture to see how the mount looks
Then just choose which chuck you want.
You can spend from $95 to over $219 depending on which chuck you choose.
I figure each kit I build saves me a good $5 in drills and untold hours of hand drilling.
Ever notice after drilling a bunch of holes by hand, you start hurrying and breaking drills? (as an 'ole timer' my hand starts to ache also)
I do have to add that the majority of the Westerfield cars built that summer were of the old hard resin type and I still only used one > drill.

The chuck and the spring shank are very precision tools and will run true.
However, since I did get a rather cheap drill press; I do have to do some fiddling to get the sensitive chuck chucked up to run true in the drill press.
Even with some wobble, the indents on the drill locations of the kits capture the drill.
The choice of what to spend is of course yours.

I also just put Victor Machinery on my favorites list. I think I will find the answer to a lot of tool questions there.

I hope Mike lets this through as it is a bit off topic.
Why spend all that money for something you do not need. Learn how to drill. The key to drilling a hole with out breaking your drill is SPEED of drill. Then drilling the hole and GETTING back out of the hole. These small drills should run at least 10,000 RPM in Aluminum, brass, wood, plastic and other soft material. Also use some lubricant if you wish. Another key to non breakage is to use stub length drill. Most drills you buy are jobber length. Drilling 5 times the drill diameter is a deep hole. The reason plastic melts when you drill is you stay in the hole to long. The heat comes from friction after you have drilled the hole and you do not get out when you should.
I do not have any of the fancy stuff you are talking and I will drill as many or more holes as you do with out breaking my drill.
I worked in a vacuum forming plant. I drill the aluminum molds with a #70 drill with 3 inch long flutes to a depth of 1 1/2 to 2 1/2 and could get over 300 holes before a drill would break.
This is not to put any one down. This is to try to teach how to do things correctly. There is a machinist's way and a blacksmith"s way doing things in a machine shop.
You will be much happier learning the correct way.
