Mitutoyo Rectangle Ceramic Gage Block Set (8 blocks per set) BLOCKS INCLUDED IN SET: 3 Blocks: 5", 6", 7" 3 Blocks: 8", 10", 12" 2 Blocks: 16", 20" Grade AS-1 Mitutoyo's Ceramic Gage Blocks offer a superior surface quality. Originally developed by Mitutoyo's ultra precision machining techniques to solve all of the problems that the steel gage block had. Features include... Corrosion-Resistant Anti-corrosion treatment is not required when handled normally (i.e. with fingers), resulting in simple maintenance and storage. No Burrs Caused by Dents, etc. Since the CERA Block is very hard, it will not scratch and is highly resistant to burrs. If a burr is formed, it can easily be removed with a ceramic deburring stone (Ceraston). Abrasion Resistant CERA Blocks have 10 times the abrasion resistance of steel gage blocks. Dimensional Stability CERA Blocks are free from dimensional change over time. Marking The black characters, indicating the nominal length, are inscribed by laser and are clearly visible against the white surface of the block. Anti-magnetic Nature Keeps Away Steel Powders High wringing force An even, dense tissue can maintain a strong wringing force. Closest Expansion Coefficient to Steel The thermal expansion coefficient of a CERA Block is quite similar to that of a steel gage block. Highly Resistant Against Drops and Other Shocks. The CERA Block material is one of the toughest ceramics materials. It is extremely difficult to crack under normal use.
