The hardened stainless steel construction and the carbide contact point make the indicators tough and durable. The design also lets you have microfine and error-free readings. The graduations marked are in contrast with the white dial face, and thus, they are easy to read. The bezel and the crystal are tightly assembled and an O-ring is introduced to prevent the entering of water, oil, or dust. The crystal efficiently resists water and chemicals. The AGD-standard compact dial indicators are the ideal tools for short-range applications. These indicators can easily be used in narrow and confined workspaces so that you get microfine readings while checking jigs and fixtures. You can make use of Mitutoyo s dial indicators when working with lathes, mills, CNC machines, etc. Mitutoyo s drop dial indicators are small-sized and easy to set up and come with a short measuring range of 0-1/4 inch. The indicators offer high precision as they comply with AGD regulations. 1411F dial indicators have a 0-50-0 reading and 0.001 inch graduation. The parts of the indicators are made of hardened stainless steel, and the contact point is made of carbide. The indicators come with a white dial face and a hard-coated scratch-free crystal.
