Boring Head Shank, 3MT

Threaded perfectly for my 3/8"-16 drawbar, and the 7/8-20 thread mated cleanly with my boring head. It's got a solid feel when you tighten it down, no wobble at all.

The 3 Morse taper seated nice and snug in my mill, zero wobble. The 7/8-20 threads were also clean and engaged smoothly with my boring head. Exactly what I needed for this setup.

Threaded perfectly for my mini mill's drawbar, so I didn't have to chase any threads. The 3 Morse taper seated tightly with no wobble, and the 7/8-20 thread mated cleanly to my boring head. Definitely a solid, no-fuss adapter for the price.
