Use with 1/4" collet routers and 1/4" shank router bits only. The router collet extension makes it possible to use all diameters of 1/4" shank bits safely. Eliminate the dangerous temptation of withdrawing the shank from the collet in order to raise the bit and to full depth of cut. Give your router bits an additional 2-1/4" when you extend them through the router table top with our router collet extension. Please clamp the shank in right place, don't clamp the shank too short or it will getting bent. Easy to use, place the router collet extension shank in the 1/4" router collet and the router bit shank in the extension collet and tighten both.
