Condition
This Mitutoyo Gauge Block Set is sold in well-used condition. Prospective buyers must note that the set is incomplete, with four specific blocks missing from the original count:
- 1.10mm
- 1.11mm
- 1.14mm
- 1.19mm
The remaining steel blocks show significant signs of wear consistent with long-term industrial use, which may include surface scratches, scuffs, staining, or minor corrosion patches. They have not been recently calibrated. The original wooden storage case is intact but shows heavy cosmetic wear, scratches, and dirt; the metal latches are functional but worn. This set is sold “as is” based on the description and photos provided.
Product details and use
This is a metric rectangular gauge block set manufactured by Mitutoyo, serving as physical standards for precision linear measurement. The set is designated as Grade 2, historically known as “Workshop Grade.”
Grade 2 blocks are generally intended for use in the workshop environment rather than a temperature-controlled laboratory. They are typically used for setting up machine tools, checking fixtures, positioning workpieces, and calibrating general-purpose measuring instruments like calipers or micrometers where extremely tight tolerances are not required. While incomplete and showing wear, the remaining blocks in this set can still serve as useful references for general shop applications.
