Victoria C. ★★★★★

Finally chucking up a drill bit without that annoying runout — the ground taper on this arbor seats snug and true. Put it on my Bridgeport and bored a test hole that came out within a thou.

Robert ★★★★★

Fits the R8 spindle perfectly—no wobble or play when tightening. I swapped out my old chuck in minutes and it’s been solid through several heavy drilling passes on steel.

Michael V. ★★★★★

Mounting my 2JT drill chuck onto the R8 spindle took less than a minute, and the fit is rock-solid with zero wobble on a test run. The steel feels properly machined, not like one of those cheap castings that need persuasion with a file. Exactly what a Bridgeport setup needs.
