This is the best hex bit holder I have seen, I've had it for a long time and don't remember the brand. It ejects the bit when the knurled collar is pulled toward the drill. Bits are inserted by just pushing them in, the collar doesn't have to be pulled back. The only thing it says on it is: "JAT PAT. PEND."
It runs true with no wobble of the bits.
The last picture shows the Snappy Tools holder for comparison.
Anybody?
