Variable Positioning Chamfer Tool. Drills, deburrs and chamfers in one operation. Converts any twist drill to a step drill and chamfering tool for countersinking and burr removal. Stocked for all standard drill sizes. Economical alternative to custom multi-diameter drills. Unlike a multi-diameter drill, the Cham-Bit can be disassembled from the drill and resharpened over and over on a radial-relief grinding fixture. Rugged collar and cutter lock to the drill shank with three set-screws and interlock for even greater strength. Optional Stop-Bit back-up spacers provide positive metal-to-metal contact for precise positioning and strength. Added stiffness of the combination tool reduces chatter and assures concentricity.
