Description
Steel spacers set the gross cutter height on the spindle; these plastic shims handle the last few thousandths. Freeborn’s 48-piece color-coded shim set for the 1/2″ bore delivers fine spacing adjustment in a single kit — each color corresponds to a specific thickness, so you can quickly identify and combine shims to reach the exact stack height the profile requires without measuring individual pieces. The plastic construction keeps shims light and easy to handle in a production environment, and the color coding eliminates guesswork. When a cutter alignment needs a precision nudge that a 1/16″ steel spacer would overshoot, these shims solve it without rearranging the entire stack. A practical fine-tuning accessory for any shop running Mini-Pro tooling on 1/2″ bore spindles.
