Infinity Tools Router Collet Reducing Sleeves, 1/2" Outside Diameter

They are available in four reductions: 1/2" x 1/8", 1/2" x 1/4", 1/2" x 8mm, and 1/2" x 3/8", so you can run a range of smaller-shank bits in a 1/2" collet router.

No. These sleeves have a 1/2" outside diameter and will not work with routers that only accept 1/4" shank router bits. They require a router with a 1/2" collet.

They feature multiple compression slots engineered into each sleeve. These slots let the sleeve flex evenly and apply the correct amount of pressure on the router bit for a secure grip.

Yes. Thanks to the built-in flange, they seat correctly and work in most standard routers that use a 1/2" collet. Explore more router accessories.

The outside diameter is 1/2", matching the 1/2" collet found in most full-size routers.

Yes, they work in any 1/2" collet router, including those mounted in a router table, letting you run mixed-shank bits without swapping routers.

Yes. The 1/2" x 8mm sleeve lets you run metric 8mm shank router bits in a standard 1/2" collet router.

The multiple compression slots apply even, correct pressure around the bit shank, which helps the bit seat concentrically for a secure hold during routing.

Place the sleeve into your router's 1/2" collet, insert the smaller-shank bit into the sleeve, then tighten the collet as you normally would. The built-in flange keeps it positioned correctly.

Consider router base plates and bushings alongside these sleeves so you are ready for template and edge work in any setup.
