ABSTRACT:
A router collet for removably attaching a rotary cutting tool to a router drive shaft is provided having a body, a split collet, a nut and a retainer for retaining the collet and nut together to permit free rotation while limiting axial movement therebetween. This construction enables the nut when loosened to initially rotate with the split collet and cutting tool for limited axial distance whereupon further axial movement of the collet is constrained causing the split collet and nut to separate and the split collet to loosen its grip upon the cutting tool shank.
