5C Collet Runout Test Arbor
The C-style (Cataract) collet, invented in 1903 by Hardinge Brothers Inc. (now Hardinge Inc.), is an open international standard used by thousands of manufacturers for holding round, hex, and square stock. Originally sizes 3C, 4C, and 5C were available, however over time larger sizes (16C, 20C, and 25C ) are available with the most common size being the 5C.
Trivia: The C designation is named after the Niagara Falls "cataracts".
The TAC Rockford 5C Spindle Runout Test Bar is the definitive standard for verifying the accuracy of your 5C collet spindles. Designed for precision toolroom lathes, indexing heads, and grinding fixtures, this test bar provides an immediate, reliable baseline to diagnose spindle health, troubleshoot vibration issues, and certify machine alignment.
