Spi 14-141-6 Test Indicator Feeler Co-ax Centering

Product Description

The SPI 14-141-6 is a replacement feeler accessory designed for use with Co-Ax centering indicators. The feeler extends the sensing reach of the indicator, allowing machinists and tool-and-die technicians to contact a bore or reference surface during centering and alignment operations. At 2 inches in overall length, this feeler is a direct-fit accessory that restores full functionality to a Co-Ax centering indicator when the original feeler is worn or damaged. Installation requires no special tools and is completed at the machine before indicating a workpiece.

This feeler is used in machine shop and tool room environments wherever Co-Ax centering indicators are employed. Typical applications include centering a workpiece or fixture on a milling machine, boring mill, or machining center. The part is appropriate for use by machinists, CNC setup technicians, and toolmakers performing bore alignment, part centering, and runout checks on manual or CNC equipment.
