Hey Routerbitworld, pull yourself together. I bought a shortened version of this (RFT1600) based on this product's picture (RFTD1600) which incorrectly shows a bearing at the end and a constant diameter between the shank and the cutting face. The actual diameter of the product is reduced and has no tip support. Instead, it just has a flat, flush surface that's 1/8 inch in diameter, which means you'll be friction-firing the jig if it's wood, or sanding it if the jig is metal, like in mine caseβ¦
