Some time ago I bought (at Banggood) three types of woodturning tools with carbide inserts and an aluminum handle. All three tool types (or others) are interchangeable and can be used with the same handle. I thought about making another handle out of aluminum to have two tools ready to use.
Commercial woodturning tools and handle
Turning solid aluminum (receiver)
Making a 31/64” hole
New handle (and old) ready to use
Now I'm planning to make a third handle.
