This arbor has a soft end which can be machined to suit your purpose.
The arbor has a case hardened 3 Morse taper shank and is threaded for a 3/8-16 NC drawbar.
The machinable end is 1.5" long and 1.5" in diameter.
Chris' Tips Most Chinese mills come with metric threads on the drawbar. However, the Morse taper tools we sell have "inch" drawbar threads. This is because we could not find a reliable supplier of tools with metric drawbar threads.
You might need to a make or purchase a drawbar to work with these tools.
