With the Dremel 4486 multi chuck, you swap accessories quickly and effortlessly by hand without needing separate collets or a wrench. Whether you are drilling, sanding, polishing, or engraving, you securely clamp bit shanks from 0.8 to 3.2 mm. This saves valuable working time during detailed projects in scale model building, jewelry crafting, or woodcarving where you switch bits frequently. The chuck supports operating speeds up to 35,000 rpm and fits most Dremel rotary multi-tools as well as the 225 flexible shaft attachment.
