This 2-Pack Precision Machining Set includes both a standard 1-2-3 machinist block and a dedicated machining jig designed specifically for producing accurate, repeatable 1-2-3 blocks. Together, they provide a complete solution for setup, manufacturing, inspection, and training applications.

The 1-2-3 block is modeled to industry-standard 1″ × 2″ × 3″ dimensions and serves as a reliable reference tool for alignment, spacing, and fixturing. The accompanying jig securely locates raw stock to streamline drilling, tapping, and milling operations, reducing setup time while maintaining consistent hole placement and squareness.

This bundle is ideal for CNC and manual machinists, toolmakers, educators, and students who want both a finished reference block and the tooling needed to reproduce it accurately. Supplied as clean, professional CAD models, both components are ready for machining, modification, or integration into shop fixture libraries.
