PrimoChill Hardline/Rigid Watercooling Tubing Finishing Bit (RFB) - Ream/Deburr/Trim - 1/2in. ID x 5/8 in. OD

This has to be, hands down, the coolest product in Primochill's catalog.I really wish I'd known about these years ago, if they were available.I had been using, like so many rigid tubing water cooling builders, the regular old deburring tool with two ends, one to scrape the inside, one to scrape the outside. This never resulted in a clean cut. This would make the tubes hard to insert into fittings, or even damage the o-rings in them.This thing, assuming you get the right size, makes a perfectly rounded edge on the end of the tubing. It can be somewhat challenging to ensure your tube and drill are perfectly square, but with practice you can get very good with it, and even at its worse its 100x better than the alternative.One of the BEST parts about it though is when fine tuning the length of the tubing after it's been bent and cut. Is it too long? Use this tool to scrub some length off and test fit.Time will tell how durable the edge of the tool is, especially when using it to shorten the tubing in the fine tuning fitment stage, since that requires a lot more cutting from the bit... but I'm very glad I found and splurged on the cost of this tool. My tubes insert into my fittings without any issues, and tuning lengths has become an absolute breeze.When coupled with the right size bending dies, the kind you screw down to your workbench, and using a tubing cutter like you'd use for brake lines or AC lines or whatever, I have a much better time making square cut ends and bending to the exact angles I need, and then finish it all off with this tool.If you do rigid tubing water cooling builds, YOU MUST HAVE THIS TOOL!!!

it works perfect.

It was my first time building a custom watercooling loop for my PC. I did not even like using distro-plates because in my opinion, they are not the classiest. So, that makes the build harder because there will be more bends to make (not much parallels when compared to using distro-plate).With that being said, this product is very effective. With the amount of tubes I had to bend, there were a lot of times where I would leave decent amount of extra tube so I can simply cut more if needed. I would test the length of my tube every so often, meaning I used to product over and over to make sure my O-rings do not get cut. I can imagine if I used a normal deburr tool, I would have had such a hard time. Using this tool would cut the amount of time to deburr to 5-10 seconds (not even when you get used to it). So, that gave me a very nice advantage of actually testing if my tubes were good to go or not, rather than wasting a lot of time deburring because I wanted to save a little more cash.Trust me, this is a tool that's worth the investment!! My only tip when using it is not to push against the tube too hard while using it. At least in my experience, it lead my tubes to become uneven. Going at it with just the right amount of force would result in a very clean/smooth ends of the tubes. Do not sweat if you used it for the first time and it feels weird, just trust the process and you will get used to it in no time!

It works really well when you get the hang of how much pressure you need to use. Too little or too much force on the tube and there’s a chance it’ll snag and snap the acrylic tube. Haven’t tried with PETG tho but I’d imagine it’s easier as it’s not as brittle as acrylic. But a very useful tool if you take the time to learn how to use it.

Like many things associated with custom water cooling, Over-priced for what it is.The goodThe bit works well and is great for shaving off small amounts of tubing so you don’t have to attempt small cuts to get the correct length.It cleans up the edges very nicely and quickly.The not so goodIt takes practice. Since you are using a hand drill, you need to make sure that you are flush or the edge will be uneven.The edge is not as rounded as it should be, making insertion into fittings a bit tough. I ended up using this bit to do the initial clean up and sizing, then used a hand deburring tool to give the edges a better rounded edge.I do like the tool. More for sizing than final prep, but I do like it, especially for fine tuning length.
