Abstract: A vibration isolating and heat insulating hand grip for use with hand held pneumatic chisels and similar pneumatic hand tools. A manually grippable rigid sleeve is slidably mounted on a housing member which surrounds a rigid, tubular shell to define an annular cavity. Internally secured to the shell is a compliant, non-porous sleeve, the shell and the sleeve defining an inflatable annular chamber. A bladder confined between the housing and the shell communicates with the inflatable annular chamber so that movement of fluid back and forth between the bladder and the chamber causes the compliant sleeve to grip or release a tool shank. Such movement of fluid is caused by an annulus internally mounted on the rigid, slidable sleeve in alignment with the bladder.
