Morse Taper Shank Extensions
Access hard-to-reach places while machining—these extensions add length to drill bits, arbors, and other tools with a Morse taper shank. Also known as drill sockets.
Slide your tool in, then press firmly to seat it. To separate the tool from these extensions, use a Morse taper removal tool.
Steel extensions have a soft body that can be machined and then hardened for wear resistance. The tang is already hardened.
Hardened steel extensions resist wear better than steel extensions.
