What is the factory tolerance for run out on the arbor?

Arbor runout is measured 1 inch out from the collet face on an appropriately sized dowel pin (use a 1/4 inch dowel in 1/4 inch collets, use a 1/2 inch dowel in 1/2 inch collets, etc.). Positition the dowel so it extends through the length of the collet bore and tighten collet firmly. Total Indicated Runout (TIR) should NOT exceed .008 inch.
