The kit includes both a centering indicator and a stationary face indicator, giving technicians the flexibility to handle a range of inspection tasks. The indicator measures from 0 to 0.25 inches with a dial graduation of 0.0005 inches and an accuracy of 0.0002 inches, making it suitable for close-tolerance work on lathes, mills, surface plates, and inspection fixtures. The 0-5-0 dial reading format with a white dial face supports quick, low-error readings in both plus and minus directions. The complete kit ships in a fitted case for organized storage and transport.\u003c\/p\u003e\n\u003cp\u003eThis kit is intended for use by machinists, tool-and-die makers, quality control inspectors, and precision measurement technicians working in job shops, manufacturing facilities, and maintenance environments. The included external feelers, internal feelers, and center point feeler cover the most common runout, concentricity, and bore-alignment checks. Contact point lengths of 2 inches, 4 inches, and 6 inches extend reach for deep-bore and hard-to-access measurement locations. The restraining arm included in the kit aids in secure indicator positioning during use.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.25 inch total measuring range with 0-5-0 dial reading format\u003c\/li\u003e\n  \u003cli\u003e0.0002 inch accuracy and 0.0005 inch dial graduation for close-tolerance inspection\u003c\/li\u003e\n  \u003cli\u003eIncludes centering indicator and stationary face indicator in one kit\u003c\/li\u003e\n  \u003cli\u003eThree external feelers, three internal feelers, and a center point feeler for versatile setups\u003c\/li\u003e\n  \u003cli\u003eContact point lengths of 2 inches, 4 inches, and 6 inches for varied reach requirements\u003c\/li\u003e\n  \u003cli\u003eFitted carrying and storage case included\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose dial test indicator kit compatible with standard indicator mounting setups including magnetic bases, holders, and fixtures that accept a 0.13 inch (1\/8 inch) stem diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use should be performed by qualified machinists or metrology technicians familiar with indicator mounting and zeroing procedures.
