BRT-222 – Pro Blind Hole Puller/Mallet Set – A major upgrade to our standard blind hole puller, this set is designed and manufactured with professional mechanics in mind. This tool set includes high-quality, heat-treated CrMo collets designed to remove bearings with an inside diameter between 8-32mm. The stainless steel slide hammer shaft doubles as a handle for a stainless mallet head and comes with two screw-in replaceable heads (brass and poly-urethane). The back side of the mallet is also machined to magnetically hold a cassette lock-ring tool, allowing the mallet to serve double duty as a lock-ring tool.
