Ideal for machinists, engineers, and automotive technicians who require precise dimensional analysis in industrial workshops or manufacturing facilities. 360degree adjustable arm with aluminum construction provides versatile positioning and reliable performance for accurate measurements in narrow or hardtoreach areas. Maintains measurement accuracy during metalworking, woodworking, or mechanical repairs where a 0.01 mm resolution matters in tight spaces. Complete set includes dial test indicators and accessories for quick setups and repeated use across multiple measurement tasks without compromising device integrity. Use scenarios: In metalworking, verify spindle alignment or fixture tolerances on crowded machine tools, such as lathes or mills, where space is limited. During automotive or engine work, check runout and alignment of shafts, gears, or assemblies in tight compartments. In woodworking, ensure jig and routerbit alignment or fixture positioning where precision in confined spaces is required.
