MITUTOYO GAUGE BLOCKS

Product Overview

Mitutoyo gauge blocks serve as high-precision length standards, fully manufactured at plants in Japan and recognized globally for accuracy, quality, and durability. Available in steel rectangular, ceramic rectangular (CERA Blocks), and steel square variants, alongside tungsten carbide options for protectors. Designed to meet strict dimensional standards (ISO 3650, JIS B 7506, and BS 4311), these blocks ensure reliable traceability to national standards.

Key Features & Capabilities

Manufacturing Excellence: Manufactured using high-carbon, high-chrome steel or special ceramic materials, thermally processed for maximum hardness, minimal aging, and dimensional stability.
Superior Wringing: Lapped measuring surfaces provide optimal flatness and fine surface finish, ensuring maximum wringing force between blocks.
Grade & Application Selection:
Grade K: Reference standard for checking gauge block calibration and academic research.
Grade 0: Calibration and inspection use for checking precision instruments and workshop gauges.
Grade 1: Inspection use and manufacturing gauge calibration.
Grade 2: Workshop use for mounting tools, cutters, and general manufacturing inspection.
