초록 ▼

A chuck 40 includes a body 42 having a plurality of angularly spaced ribs 166, 168 and 170 formed in a forward cylindrical opening 48 thereof. A locking element 236 is movable within a passage 180 of the body 42, and is formed with a defined portion 242 which is extendable from the passage 180, through an inboard peak surface 172 of the rib 166 and into the opening 48. An actuator 44 is coupled to the locking element 236 and is biased by a spring 250 to urge normally the defined portion 242 of the locking element into the opening 48. A bit 62 is formed with a shank 96 with three grooves 100, 102 and 104 extending axially to a free end 112 thereof. A pocket 114 is formed in a base of each of the grooves 100, 102 and 104. The bit 62 can be manually inserted into the opening 48 of the chuck 40 such that the grooves 100, 102 and 104 are located drivingly over at least portions of the ribs 166, 168 and 170, respectively. In addition, the defined portion 242 of the locking element 236 is located biasingly within the pocket 114 to lock the bit 62 with the chuck 40.
