Precision Matthews D1-4 chuck "Speed chuck adapter"
hi folks.
after receiving this new Precision Matthews D1-4 chuck, I quickly realized that to screw the collet in was especially arduous, I had a harbor freight pack of 3 drill/shank attachments that worked real well chucked up in my drill (on screw drive setting) I had to mill a bit off of 3 sides (didnt bother with the side that had the detent ball) it worked a charm.
