Don't let collet and cutter mismatches hold you back! Shaper's complete collet kit includes all basic collet increments in imperial and metric measurements up to 1/4" and 8 mm, respectively. Every project starts with the right cutter and a collet that's designed to accommodate it. Don't rely on after-market adaptors or approximations that can jeopardize your cut quality, cutter and project. Each collet set includes a Shaper Micro-Systainer with customized foam insert to protect and store your collets.
