This stainless steel set is an important upgrade to our standard blind hole puller and has been designed and manufactured for professional mechanics. This tool kit includes high-quality, heat-treated stainless steel collets that are designed for the removal of bearings with an inner diameter of 8-32 mm. The handle of the stainless steel slide hammer also serves as a grip for the stainless steel mallet head and comes with two interchangeable screw heads (brass and rubber). Additionally, the back of the hammer is machined to securely hold a cassette ring tool magnetically, allowing the hammer to also be used as a retaining ring tool.
