The feeler arm serves as the contact point that transfers workpiece surface position data to the indicator mechanism, enabling accurate centering and alignment during setup operations on mills, lathes, and machining centers. At 4 inches overall length, this feeler provides the reach needed for standard Co-Ax indicator applications. Machinists and toolroom technicians install this component when the original feeler is worn, damaged, or lost. It weighs approximately 1 pound and ships as a single unit.\u003c\/p\u003e\n\u003cp\u003eThis feeler is suited for machine shop environments where Co-Ax centering indicators are used for workpiece location, bore centering, and fixture alignment. Typical applications include CNC and manual milling setups where precise centering of round features is required before machining operations begin. It is a direct accessory replacement intended for professional machining and toolroom use.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4 inches overall length for standard Co-Ax indicator reach\u003c\/li\u003e\n  \u003cli\u003eDesigned as a direct accessory replacement for Co-Ax centering indicators\u003c\/li\u003e\n  \u003cli\u003eSingle-unit packaging suitable for individual replacement needs\u003c\/li\u003e\n  \u003cli\u003eCompact form factor supports precise workpiece alignment tasks\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Co-Ax centering indicators.
