The industrial high precision machined collet reduction sleeve enables collet sizes to be reduced to accept CNC and router bits with smaller shank sizes. Reduction sleeves are produced with high quality steel and precisely machined to limit the chance of run-out. Reducing the sleeve is not a long term solution, for best results using the correct size collet is strongly recommended.
