Our machinist 123 blocks with no holes are ideal for use as parallels, but they’re also necessary in other situations. Due to case hardening, our hole-less machinist blocks don’t mark up easily, and the unique hole-less feature prevents chips from getting stuck in the block. Each pair that you receive will match one another exactly. These machinist 123 blocks with no holes are heavy-duty, long-lasting, and reliable.
