For sale is a beautiful condition, smoothly operating MT4 Jacobs 20N ball bearing SuperChuck. It operates so easy that even a baby could turn it. I ran it through its entire range. The smooth ball bearing ensures greatest clamping force. Includes original Jacobs K5 key with nickel handle. This handle is designed to bend before it damages the chuck, even if some fool uses a pipe extension. This protects your investment,
Capacity 3/8" up to 1". Taper is MT4.
