SPECIFICATIONS: (D) Diameter: 1/2; (d) Shank: 1/4; Overall Length (L): 1-3/16. Review: Works perfectly to use 1/4” bits in a 1/2” router. - Works perfectly for my needs. I was gifted a monster 1/2” router but the majority of bits found at local stores are all 1/4”. I’m not trying to pretend to be a professional woodworker, my name is not Bob Villa or Norm Abrams. I don’t need commercial grade 1/2” bits to do minor home projects. This makes using more easily available bits possible, which is perfect for me. Review: Very simple but very useful. - 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. ## Features - SPECIFICATIONS: (D) Diameter: 1/2 (d) Shank: 1/4 Overall Length (L): 1-3/16 ## Technical Specifications | Specification | Value | |---------------|-------| | Thread Size | 1/2-20 UNC | | Manufacturer | Amana Tool | | UPC | 738685128121 | | Part Number | RB-128 | | Item Weight | 0.96 ounces | | Package Dimensions | 5.55 x 1.93 x 0.51 inches | | Item model number | RB-128 | | Item Package Quantity | 1 | | Cutting Diameter | 0.5 Inches | | Batteries Included? | No | | Batteries Required? | No | ## Product Details - **Brand:** Amana Tool - **Material:** Alloy Steel - **Item Diameter:** 0.5 Inches - **Item Weight:** 27.22 g - **Compatible Devices:** Drilling Machine, Milling Machine ## Images ![Amana Tool RB-128 High Precision Steel Router Collet Reducer 1/2 Overall D x 1/4 Inner D x 1-3/16 Inch Long - Image 1](https://m.media-amazon.com/images/I/41wnJtUdZ1L.jpg) ## Available Options This product comes in different **Model** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works perfectly to use 1/4” bits in a 1/2” router. *by T***5 on December 7, 2025* Works perfectly for my needs.
