Tapping Chuck, 33JT

Threw this on my benchtop mill with a 33JT arbor and it's been a huge upgrade from cranking taps by hand. Reverse the spindle to back the tap out and it works fine; just remember it isn't a self-reversing head. Tapped a dozen M8 holes in steel without breaking anything.

Finally got tired of hand-tapping on the lathe, and this chuck turned my old bench mill into a proper tapping setup. Running M8 threads in aluminum is night and day now; just remember to reverse the spindle to back the tap out.

Chucked this on my mini mill and tapped a dozen M6 holes in aluminum without a single broken tap. You do have to reverse the spindle to back the tap out, but that's clearly stated and easy once you get the rhythm. Way cheaper than a dedicated tapping head and it does the same job.
