Big Horn 19698 1/4" Router Collet Replaces Makita 193214-9. Can be used in two ways: as a straightforward replacement collet, or to enable a router to handle shank bits measuring 1/4 In. Its clever design also allows the router bit, collet, and collet nut to be removed as a single, unified unit, which helps prevent any time-wasting, immovable bits that won't budge.
