• Available in steel and CERA and block sets
• Specific, repeated heat treatment of steel blocks reduce deterioration change over time
• CERA blocks are free from dimensional change over time; have 10 times the abrasion resistance of steel gage blocks
• Advanced lapping techniques achieve the best flatness, surface roughness needed for gage blocks
• Designed to check and calibrate longer measurement instruments
• Black characters on gage blocks are inscribed by laser and clearly visible
• Provided with Inspection Certificate
• Supplied in a solid wooden case

The Mitutoyo Inch Rectangular Long Block Gage Block sets offer exceptional precision and stability for calibration and manufacturing traceability of longer workpieces. Gage block sets are available in different grades, sizes and steps, offering exceptional precision and stability for calibration and manufacturing traceability. The Mitutoyo innovative lapping technique makes our gage blocks some of the most accurate and trusted instruments in the world, featuring exceptional flatness and ideal surface roughness. Our steel gage blocks are constructed of high-carbon, high-chrome steel while our CERA gage blocks are constructed of ceramic materials with superior surface qualities and corrosion resistance.
