Your cart is empty.Our Industrial high precision machined collet reduction sleeves enable collet sizes to be reduced to accept CNC and router bits with smaller shank sizes. Reduction sleeves are produced with high quality steel and precisely machined to limit the chance of run-out. Reducing the sleeve is not a long term solution, for best results using the correct size collect is strongly recommended.#Rb-102, diameter (D): 1/4, shank (D): 1/8, overall length (L): 1, RB-102 High precision steel Router collet Reducer 1/4 overall DIA x 1/8 inner DIA x 1 inch long

Just a small steel tube with a split on one side but it is very accurately manufactured to fit between a 1/4 inch collet chuck and a 3/16 inch shaft mill or drill while maintaining near perfect concentricity.Opens up a whole additional range of tooling for my routers and die grinders.

It works as designed. It's well made and should continue to hold bits well for a long time.

This worked well to replace my beat-up Makita collet that became difficult to remove bits from. The Amana has a different design that I hope holds up better but is otherwise the exact same size. It has 4 segments, but none run the full length of the collet and all 4 cuts are through the entire thickness of the collet versus the Makita that had one full cut through the entire collet while the other 3 were only scored the entire length.

Cleaned it with brake cleaner and dropped it into my router. Tightened it down normally, and it held my 1/4" shank bit very well. No slip like the old one that no longer holds a bit.

This 8mm collet fits 5/16 router bit perfect. I bought a 5/16 collet and it was too tight.

This is my second one in 40 years of owning this router. Use mostly 1/2" bits , but this always good to have when I have to use 1/4" bits.

Well made. Fast shipping arrived earlier than promised. Clean tool, no remaining burrs. Perfect fit to my original 1/4" collet and every 3/16" cutter I've used in it so far.

I had an issue with another Amana 1/4 to 3/16 reducer that barely clamped onto an end mill. This 1/4 to 3mm is even worse. It can not even clamp onto the 3mm endmill no matter how tight you lock down the collet nut.The Amana 1/4 to 3mm reducer has a single slot cut on the side but because of the thick wall thickness it can never clamp down onto a 3mm end mill no matter how tight it got the nut. Don't buy this reducer because you will waste your time trying to use it.
