Series 99® service kits and sets are made up primarily of various screwdrivers, nutdrivers, and other blades, which can be used interchangeably in Series 99® handles. All blades are high quality steel, hardened and tempered for optimum performance. Plastic handles have a patented spring device that holds blades firmly, yet permits quick, easy insertion and removal. Regular handles accommodate all blades, single and reversible. Stubby, Tee, and Ratchet handles can only be used with single-end blades.
