Color-Coded Plastic Shim Set — 1/2” Bore, 48 Pieces (.003”–.030”)

Dials in the height of a stacked cutter setup when standard spacers land close but not exact. Forty-eight shims in eight thicknesses — .003″, .005″, .0075″, .010″, .0125″, .015″, .020″ and .030″, six of each — colour-coded so you can pick the one you need by eye rather than reaching for a micrometer, and boxed in a reusable clear case that keeps the sizes separated on the bench. Sized for a 1/2″ bore. The same set is available for other spindles: AC504 for 3/4″ bore, AC505 for 1″ bore and AC507 for 1-1/4″ bore. Shim stacks are what turn a spacer kit from approximate to precise, and having the full range on hand is the difference between a setup that takes a minute and one that takes twenty.
