Has anyone tried this kind of design by the way? I thought about getting one many times just to try, but somehow always forget https://www.youtube.com/watch?v=5f9SkIP98u8
this may be a bit more than what the op was asking for, but when i go for a screwdriver that is more than what my Surge can handle, i grab my kit that never lets me down.it is my custom assortment of 6" long round shank bits with a Klein Switch driver handle and a Dewalt Gyroscopic power screwdriver. tucked in along side is a Klein 4in1 electronics screwdriver with phillips, flat and torx mix, some cobra style pliers and mini Klein cutters. (i guess you can tell i like Klein)all wrapped in the smallest Veto pro pac tool pouch they make.for facility maintenance, that kit does 90% of my job.I cant say enough about the Dewalt power screw driver. i think it is severely under appreciated. most people have never seen them. but it can drive 3" screws into solid wood and has a fine touch and control that is made for locksmiths and electrical work. I have been using it every work day for 5 years and on the same 2 original batteries. best power screwdriver on the market that i have seen.if i want more torque than it can handle or space is limited then the Klein Switch is the king.the bits snap in tight with no play at all even after many years of use.oh, and the best thing about the Veto pouch is besides the great quality, i can hold it upside down and nothing falls out. even the bits stay firmly in place but easy to pull out due to a couple of small magnets that i dropped into the bottom of the pocket. you could hang over the side of a building with a harness and have it dangling from your side with no fear of anything dropping even when you pull other tools out.

Here is the other picture of the tip in the unlocked position.
Yes those are screw starters I still have two back in the day I used them when installing points in older cars.Mike
Got these little gems in an old machinists' tool box I bought several years ago.Some are marked Blue Point(a Snap-On secondary brand)and others are unmarked.The two that are made of nylon I believe are used while working on electrical components.The smaller one is marked,"Aircraft Spec".To remove a screw,you turn the shaft while holding the end and this aligns the small section in the middle of the tip with the screw slot.Press onto the screw and start to loosen(counterclockwise)and the spring loaded center part of the tip locks the driver onto the screw.To install a screw,fit the tip into the slot and turn the handle again counterclockwise which engages the center of the tip with the slot;holding the screw. Insert the screw into the hole and start to tighten(clockwise)and the spring loaded center aligns with the slot and releases from the head. Great for working with non-magnetic stainless steel screws.
