Mitutoyo BM1-8-1B/PD Gauge Block Set

• Calibration of measuring instruments such as micrometres, callipers, and height gauges.
• Setting and verifying machine tool offsets and workpieces.
• Precision inspection of manufactured parts for dimensional accuracy.
• Establishing reference standards in quality control laboratories.
• Tool room applications for jig and fixture setting.

Block Material

Typically high-chromium alloy steel, ceramic, or tungsten carbide for durability and stability.

Number of Pieces

Sets commonly range from 30 to over 100 pieces, with 81-piece sets being standard for comprehensive coverage.

Grade

Available in various grades (e.g., K, 0, 1, 2), with higher grades offering tighter tolerances for more demanding applications.

Surface Finish

Ultra-micro-lapped surface finish is typical for precision wringing and accuracy.

Block Shape

Rectangular blocks are standard, allowing for wringing together to form precise lengths.

Compliance

Units of this type typically meet or exceed international standards such as ISO 3650, ASME B89.1.9, and JIS B 7506.

Storage

Supplied in a fitted, protective case for organised storage and to prevent damage.

• What is the significance of the grade of a gauge block set?

  The grade indicates the manufacturing tolerance and accuracy of the blocks. Higher grades (e.g., Grade K or 0) offer tighter tolerances and are suitable for primary reference standards, while lower grades (e.g., Grade 1 or 2) are used for workshop and inspection applications.

• How should gauge blocks be maintained?

• What does 'wringing performance' refer to?

• Can these gauge blocks be used in any environment?

• What is the typical lifespan of a gauge block set?

Calibration weights and kits are essential for maintaining measurement accuracy across laboratories, biotech and pharmaceutical facilities. Buyers typically prioritise certified traceability, material quality and condition of surface finish when purchasing used sets. Industry sentiment favours equipment from established manufacturers with documented calibration history. Common strengths include durability and long operational lifespan when properly stored. When buying used, verify calibration certificates, inspect for corrosion or damage, and confirm all weights in the set are present and accounted for.
