With the Mitutoyo 102-708 outside micrometer, you achieve reliable external measurements from 25 to 50 mm. Its vernier scale enables precise readings down to 0.001 mm, making it an essential tool for cnc machining, metalworking, and rigorous quality inspection. The dual-action ratchet thimble works from both the thimble and the speeder, providing smooth one-handed operation and a constant measuring force for consistent repeatability. Durable carbide-tipped measuring faces protect against wear, while the heat-insulated frame prevents body heat transfer from compromising measurement accuracy. Use the included 25 mm setting standard to quickly verify zero alignment and start measuring with complete confidence.
