PrimoChill RFB Rigid Tubing Finishing Bit - 1/2in. ID x 5/8 in. OD

This us an essential piece of kit for hardline watercool enthusiasts. Hand reaming is time consuming and has less then perfect results. The RFB is awesome!! Fast, easy and absolutely perfect tube ends everytime. Even can be used to precisely trim the end fractions of a mm at a time. Excellent product. PrimoChill knocked it out of the park again.

Arrived safe and sound. Tested it out to see how it works and it works great. Much better than the hand held plastic ones that comes in kits. Highly recommend.

this thing is amazing. Chuck it up in a drill and what this make perfect chamfers for your tube ends. In most cases, you'll have a hand-held cutter with razor blades inside. After 2-3 pipe cuts and you'll notice the ends will start to get rough for the outside diameter of the tube making it necessary to sand them to smooth them out. This takes all of that away and gives you perfect inside/outside finishes. After a dozen or so tubes, this still cuts perfectly. Great tool

Works perfect

I haven't had a chance to actually use it yet, but it should work great after a minor mod to it. After reading about people having bearing issues, like the bearing being a little too small and wobbles while using the tool. I have found bearings that are a little closer to the advertised measurements of the 1/2" id, 5/8" od bearing. I found them on Amazon and the manufacturer and part number is," Uxcell R188ZZ. Also. If anyone wants to put a custom bearing on it, the I.D. of the the bearing is 1/4"
