Gauge Ball Set M318.511 — hardened steel, 1–25 mm, 50 pieces

Gauge Ball Set M318.511 provides a complete collection of precision reference spheres for inspection, calibration and go/no‑go checks in workshops and quality labs.

• Hardened steel, 60 ±2 HRC
• 0.0025 mm accuracy for precise checks
• 50-piece set, sizes 1–25 mm, double each
• Compact, organised set for workshop use

Consistent reference accuracy that speeds up inspection

The set is designed for reliable dimensional checks and reference tasks where repeatability matters. With an indicated accuracy of 0.0025 mm, the spheres serve as stable reference points for comparative measurements, runout checks and tactile gauge inspections. The precision class reduces measurement scatter and helps to lower rework rates by ensuring a dependable baseline during incoming inspection and in‑process checks.

Hardened construction for durable, long‑term use

Manufactured from hardened steel and specified at 60 ±2 HRC, the spheres resist indenting and wear during regular use. This material choice preserves the spherical form and dimensional integrity even under repeated contact with fixtures and measuring instruments. The combination of wear resistance and balanced hardness makes the set suitable for routine shop use as well as for bench calibration tasks, extending the usable life of the reference set and protecting measurement investment.

Practical set composition for everyday workflows

Delivered as a 50‑piece set with two units per nominal size from 1 mm to 25 mm in 1 mm steps, the collection supports quick selection for both micro and small‑component applications. The paired sizing enables cross‑checks and immediate verification of measurement chains. At a total mass of 1.3 kg, the set is portable while remaining robust enough for stable handling; the organised layout helps to keep the spheres accessible and reduces time spent searching for the correct diameter during production or inspection routines.
