Collets, 3 Morse Taper, Individual Sizes

The drawbar thread is a perfect 3/8"-16, so my spindle setup took zero fiddling to get snug. These collets feel solidly built, and the 3.39-inch length clears my quill without any binding.

The precision grinding on these collets is immediately noticeable—they seat perfectly in my spindle without any wobble. The 3/8"-16 drawbar thread matched my existing hardware exactly, which saved me from having to buy adapters.

Finally got around to swapping out my old collets and these seat perfectly in the taper, no wobble at all on the spindle. The 3/8"-16 drawbar thread matches my setup exactly, and the 3.39 length feels solid when tightening.
