💡 Why do machinists prefer solid alloy shaft extenders over hollow ones for CNC routers?
Finding a stiff extender kills vibration way faster than loose tubing.
- Ground bores hold your shanks tight so you can push through thick metal fast.
- Even weight balance keeps rotation smooth even when you’re hogging material.
- Easy swap design means less wrench time and more production hours logged.
