CHUCK, BIT, ASSEMBLY THEREOF AND METHODS OF MOUNTING |
摘要 |
A chuck (40) includes a body (42) having angularly space ribs (166, 168, 170) 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 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 portion (242) of the locking element (236) into the opening (48). A bit (62) is formed with a shank (96) with three grooves (100, 102, 104), having pockets (114) formed in their bases, extending axially to a free end (112) thereof. The bit (62) can be manually inserted into the opening (48) of the chuck (40) such that the grooves (100, 102, 104) are located drivingly over at least portions of the ribs (166, 168, 170), respectively. The portion (242) of the locking element (236) is located biasingly within the pocket (114) to lock the bit (62) with the chuck (40). |
