The feeler serves as the contact element that transmits positional deviation to the indicator body, enabling precise centering and alignment of bores, holes, and circular features on the machine tool. At 4 inches in overall length, it provides the reach needed for standard Co-Ax indicator setups. Installation and use are performed by machinists, toolmakers, and CNC setup technicians working with milling machines, machining centers, or jig borers.\u003c\/p\u003e\n\u003cp\u003eThis feeler is applied wherever a Co-Ax centering indicator is used to locate part features relative to the machine spindle centerline. Typical applications include finding the center of a bore, aligning a vise or fixture, and setting up repeat operations that require high positional accuracy. The 4-inch length suits the majority of standard Co-Ax indicator configurations encountered in production and toolroom environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4-inch overall length for reach in standard Co-Ax indicator setups\u003c\/li\u003e\n  \u003cli\u003eDesigned as a direct-fit accessory for Co-Ax centering indicators\u003c\/li\u003e\n  \u003cli\u003eReplacement feeler keeps existing indicator bodies in service\u003c\/li\u003e\n  \u003cli\u003eCompact and lightweight at 1 pound packaged weight\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Co-Ax centering indicators as stated by the manufacturer.
