💡 What are R8 collets used for in a machine shop R8 collets keep end mills and drill bits centered while they spin at high speed. They fit straight into the spindle of most manual mills and lathes. The 7/16-20 threads let a drawbar pull the collet tight for a solid hold. A full set gives machinists quick access to many common tool diameters without changing holders. Ground surfaces maintain runout under 0.0006 inch so parts stay within tight specs.
