Hannah ★★★★★

The 3mm diameter fits perfectly in my lathe tailstock alignment holes, no slop at all. Each pin in the pack has clean, uniform edges that slide in smoothly—exactly what I needed for doweling two small steel plates together.

Ella I. ★★★★★

I've been using these pins for jig alignment on my mini lathe, and the 12mm length is just right for the through holes I drilled. The 3mm diameter slides in smoothly without any slop or binding—exactly what I needed for repeatable setups.

Sofia ★★★★★

The 3mm diameter fits perfectly into my mill's indexing head holes without any slop. These pins are precisely ground, making alignment work much easier than using random hardware store dowels.
