Extension M3, ceramic L 50,0mm stem Ø4,0mm, end pieces stainless steel K651162 Mitutoyo

Extensions are required when the measurement location cannot be accessed with the stylus alone, for e.g. to reach features in bores and hard to access areas on the workpiece. The very lightweight and extremely stiff character of ceramic materials and its low thermal expansion, makes it the ideal material, especially for long stems and extensions. The brittle characteristic can protect probes from the effects of crash.
