From the how-the-hell-did-we-miss-that-one department, last summer Milwaukee introduced an arbor that you twist to release the hole saw. Forget about un-chucking the arbor to change hole saws; no more knuckle-busting wrenches to loosen the jammed nut holding on the saw — just twist the base of the arbor and the hole saw pops free.
The system does have its limitations. It only works with hole saws up to 1-3/16″, which isn’t large for a hole saw. The arbors are available with 3/8″ or 7/16″ shanks and supposedly work with all hole saws, even non-Milwaukee ones.
To get you started, Milwaukee sells a kit with the arbor and a selection of hole saws. The kit includes 3/4″, 7/8″, 1″, 1-1/8″, and 1-1/2″ hole saws, a twist release arbor with pilot bit, an extra pilot bit, an adapter (maybe to use the 1-1/2″ bit?), and a 1/18″ hex key, all in a hard plastic case.
Pricing for the kit starts around $45 before shipping. You can buy the arbor by itself for about $15.

Milwaukee makes an arbor similar to the DeWalt arbor, it’s a simple upward pull and the saw is released. A few bucks less as well.
If you put a few pieces of masking tape or a nylon washer between the hole saw and arbor, you’ll never have trouble getting them off again. It prevents the threads from jamming up tight. Just thought I’d throw that one out there.
Bosch makes one too, and I would imagine Starrett does too. The exact implementation is different on the Bosch but it does the same thing.
