Othermill Collet


Replacement ER-11 collet for 1/8" diameter shank bits. This collet is not only meant to grasp your 1/8" shank tools, but it also ensures that they spin concentrically with the tool holder. Leaving dirt or debris in your collet can yield poor finishes and seriously decrease the life of your end mills, so it should be cleaned thoroughly before use. Refer to our maintenance guide for other useful tips.
