These three-jaw chucks have 1/4" hex shanks, allowing you to use small-diameter round shank accessories (bits, mandrels, burrs, etc.) in a quick-change chuck.
The small chuck has an adjustment range of 1mm to 3mm, and the large a range of 3mm to 6mm. Particularly useful when switching between pre-drilling for and driving screws. You can even use them as a nail spinner when you have no bit at hand.
An excellent buy on well-made chucks. Quantities are limited.
These products are not stocked at our retail stores but can be ordered for pick-up at our stores.
