Abstract

A quick release chuck device includes a body member having an internal longitudinal bore with a substantially rectangular cross-section shape for receipt of conventionally sized saw blades. An engaging device is movable JP19960240043 at least one radial bore in communication with the longitudinal bore through one of the short sides of the body so that at least a portion of the engaging device extends into the longitudinal bore to hold a saw blade.. A spring-biased outer sleeve is disposed about at least a portion of the body member. The outer sleeve is movable longitudinally between a released position and a locking position. The outer sleeve member includes an engaging surface having a portion which forces the engaging member radially inward to engage a saw blade in the locking position of the sleeve member. The chuck is unlocked by moving the outer sleeve to its released position thereby allowing the engaging member to move radially outward to release the saw blade.
