Porter Cable 42999 1/4-in. Router Collet

Designed to prevent frozen or stuck bits from slowing down your woodworking projects, you can remove the collet and collet nut as one unit, helping to prevent lost bits. It can be used to replace lost collets or to convert 1/2-inch bits to 1/4-inch bits, so you can use them with your 3 1/4-HP PORTER-CABLE® router.
