Customer Reviews (4.8 / 5 · 5 reviews)

Isabella N. ★★★★★

The surface finish on these parallels is incredibly smooth, at Ra0.4um as described, and they've held up perfectly after several dozen setups. I also appreciate the precise 6" length for my small work area.

Chloe ★★★★★

Finally, a set of parallels that actually stay within a tenth across the whole length. The ground finish on these is so smooth they practically slide into place under a workpiece.

Isabella Y. ★★★★★

I needed a fresh set for a tight tolerance job and these delivered perfectly. The Ra0.4 surface finish is smooth enough that I don't worry about scratches on my workpieces, and the 56-61HRC hardness means they'll hold up for years.
