Orion Hardened & Ground Parallel Pairs - 125x10x18mm

The ORION Hardened & Ground Parallel Pairs are precision blocks designed for parallel mounting of workpieces in machine vices, on CNC or manual machine tools, and other tooling setups. These blocks are supplied as a matched pair to ensure true parallelism under load, delivering reliable and repeatable clamping results.

Sized at 125 × 10 × 18 mm, they combine hardened steel with exacting grinding to resist wear and maintain flatness through repeated use. The pair has a matching pair tolerance of 0.01 mm and a nominal tolerance of ±0.02 mm, giving you consistent, high-accuracy alignment across multiple setups.

• Matched precision pair (0.01 mm): ensures both blocks sit in perfect parallel contact, reducing setup errors and rework.
• Hardened and ground finish: delivers durable surfaces with long-lasting flatness that resist wear in tough machining environments.
• Compact, versatile size (125 × 10 × 18 mm): fits standard vices and fixtures for fast, repeatable placements and streamlined workflows.

With these parallel pairs, you gain faster, more confident setup, improved clamping accuracy, and dependable performance across milling, drilling, and grinding operations. The hardened, ground surfaces help extend tool life, while the precise tolerances keep your workpieces consistently aligned, enabling higher quality results and smoother production.
