Precise dimensional analysis for machinists, engineers, and automotive technicians in industrial workshops and manufacturing facilities. Complete set includes dial test indicators and accessories for quick setups and repeatable measurements across multiple tasks without compromising instrument integrity. Flexible base holding stand with a permanent magnet provides secure attachment to machine tools, ensuring stability and protecting the measuring device and work surface during precise adjustments. Aluminum construction and a 360degree adjustable arm offer versatile positioning and reliable performance for accurate measurements in narrow or hardtoreach areas. Use scenario: perform setup and alignment checks on milling or drilling machines to verify runout, straightness, and parallelism. Use scenario: conduct dimensional checks on automotive components during assembly or , such as adjusting or verifying tolerances on shafts, gears, or related parts. Use scenario: inspect features in confined spaces on fixtures or assemblies, using the adjustable arm to reach difficult areas with stability and precision.
