Many years ago, there was a great vendor at the SnF FlyMart hangar that sold drill bits. Many of them had this strange base - cylindrical, a little more than a quarter inch in diameter, with dimples in it. They chucked up fine in a regular drill, and I have used them that way for years (bigger drills, mostly), but I never really looked in to what they were. Well our friend David Howe showed me the system at his shop - the Boeing Quick Change chucks - but I held off converting because it seemed sort of an expensive way to go. I finally succumbed however, and now I am changing (almost) everything in the shop! Hint if you go this way - Ebay is your friend….. you can buy lots of #40, #30, #20, #10, and 1/4” bits, as well as the chucks for reasonable prices.
For years, I have kept one drill set up with a #40, and one with a #30 - and kept an electric drill with a friction chuck handy for all the other sizes. But with the Quick change, it is so fast and easy to swap bits that I’m change all the pneumatics to those.
I still have to convert my countersink cages and a few other specialized things - and you do still need to keep a regular chuck drill around for oddballs like #21, #27, #19…. But these will do for the acreage drilling!
(Now if anyone can tell me how to get the regular chuck off of our Taylor palm drill…..)
Absolutely a “First world luxury item”, admittedly!!
