Customer Reviews (4.6 / 5 · 5 reviews)

Aurora Y. ★★★★★

I swapped the motor controls onto my old column in under an hour, and the R8 spindle runs much smoother than the stock one I had before. The built-in variable speed dial really helps when switching between steel and aluminum.

Stella ★★★★★

The whole head assembly came as one solid unit, so swapping out the old one on my mini mill took barely an afternoon. The R8 spindle seats the collets cleanly and the motor controls are responsive right out of the box. Exactly what I needed to get back to cutting.

Daniel ★★★★★

The motor runs noticeably smoother than my old one, and the variable speed control gives me precise cuts on aluminum. Everything fit right onto my column with no fuss, and the spindle feels solidly built. Really happy with this upgrade for my workshop.
