Mitutoyo Rectangular Gauge Block, Ceramic, Grade 1, 5mm, 613615-03

■ Superior Surface Smoothness Cerablocks, born from ceramic materials and Mitutoyo's ultra-precision machining technology, eliminate all the problems associated with steel gauge blocks. ■ Rust-Free Can be handled with bare hands, and no rust prevention treatment is required after use, even in humid locations. ■ Less likely to burr due to scratches Even if scratches are made on the measuring surface, burrs are unlikely to form. If scratches do occur, they can be removed with the ceramic grinding wheel "Ceraston." ■ Excellent Wear Resistance 10 times more wear-resistant than steel, extending its life cycle. (Manufacturer comparison) ■ No Change Over Time The JIS standard for gauge blocks allows for a change of ±0.045 μm/year (for a 100 mm gauge block), but CERABLOCKs show virtually no change over time. ■ Easy-to-Read Markings Clear black text on a white background for clear reading. ■ Non-magnetizable and does not attract iron particles. ■ High Adhesion The uniform, dense structure ensures sustained high adhesion. CERA Blocks, created using ceramic materials with excellent surface smoothness and Mitutoyo's ultra-precision machining technology, eliminate all the problems associated with steel gauge blocks. Nominal size: 5mm Grade: Class 1
