Vブロック、1-1/4 x 1-1/4 x 1-5/8インチ、Fisher

The concentric ground finish on these V-blocks is impressive. I’ve been using them to set up work on my surface grinder and the parallelism is dead-on.

The squareness check on my mill vise came out dead-on, and I'm honestly impressed how rigid these feel once clamped. They're heavier and more solid than the cheap set I had before, so the matched pairs are definitely earning their keep.

Matched to within 0.0002" is no joke — I checked mine against a surface plate and they're dead on. The hardened steel has held up through a week of heavy layout work without a single nick, and the clamp set keeps everything locked tight.
