I recently got a festool t12 and I am very happy. My only issue with it is that the jacobs chuck is kind of heavy for me since i mostly just use small drill bits, but I do appreciate it since I know I can use huge drill bits. I made this thing to try to stabilize drill bits while spinning and to make it harder for it to pull out, and it does the job quickly and easily but has two major drawbacks, it requires two hands and the binder clip can hit your hand, at full rpm it hurts a little but is not dangerous.
To make, I used a binder clip with these dimensions: 3.2cm length, 2cm depth, and 1.4cm width. I used one sticky felt pad with 3mm thickness used for putting beneath furniture to not scratch floors, I then cut into multiple strips, using only three strips of about 3mm length and width. I stuck the strips at the very edge of the binder clip but I think putting it right where there are locking indentations on the drill hex bits would be better at the expense of requiring more work opening the binder clip to insert drill bits. You'll have to trial and error cut the thickness of one of the three felt pads, because one side has a bulge due to the binder clip design (the top part if you look at my pics showing the face of the drill) and also be a tiny bit closer to the center of the drill than the other two sides that are half-open. Fine adjustments in placement and thickness can make this a useful contraption, and with a binder clip of the dimensions I gave above you will be able to put felt anywhere in the upper half of the binder clip while the other half grips onto the drill. The binder clip can be clamped onto the drill either from the side or from the front, front insertion being easier. I think I will eventually wrap the metal handles for more comfortable use and less painful when I am accidentally hit by it.
Edit: Actually it can be switched with one hand, but it requires a lot of steps. First remove binder clip from the side, remove drill bit, insert new drill bit, put back binder clip. I prefer to put the bottom of the drill against my body, hold onto the top of the drill with one hand while pulling slightly on the binder clip, remove and insert new drill bit. Sigh can someone just make a fake centrotec for hex drill bits

I thought by bit holder it meant the extension accessory that comes with the centrotec starter kit. I have placed an order for that collared bit holder, thanks so much!
