    You won't need them constantly, but nice to have when you do. I have an RCBS motorized case prep station, and am completely spoiled by it. I brush out every pocket because it is so easy. On the occasion when I get a case that has a burr in the flash hole, the reamer cuts it right out. I inspect all the new cases the first loading, the same if I get used cases I have not loaded. you can live with a bit of crud in the case, not so in the primer pocket or flash hole.

      I was more asking if any of the tools accomplished what the other tool does. They seem very similar in description.

      Does a primer pocket uniformer also clean the primer pocket?

      Does a flash hole uniformer also debur?

      If I need all 4, it's fine. I just don't want to buy something I don't need.

      I looked really strong and hard at that RCBS prep station. I'm sure I'll be there sooner or later. It was actually in my cart, then I removed it. I saw a video on youtube where someone modified a lyman handheld case trimmer to work on that prep station. It looked pretty good and looked to save a bunch of time.
      Don't panic bro.

        The Lyman and RCBS flash hole tools do the same you only need one. If you don't have a case mouth deburring tool you need one of these.


        When you trim rifle brass, it leaves a burr around the mouth, so you need a deburring tool to clean the burrs from inside and outside the mouth.

        Some manufacturers drill their primer holes and others punch them. The drilled ones will be clean with no burrs, the punched ones will have a burr sticking up inside the case. This burr can deflect some of the primer blast so it needs to be cleaned out so you need that tool also.

        The pocket uniformer cuts away the sides and bottom of the primer pocket and only needs to be used one for that purpose. I find it better to do that by hand and not with a power tool, so that you have a better feel for how much cutting away your doing. You can't replace it if you take too much off.

        The pocket cleaner helps with seating a new primer in to a clean and properly sized primer pocket. What that means is you need to use a power drive setup or risk carpo tunnel in your wrist from all the turning. I lean toward stainless steel media cleaner. Deprimed cases can be cleaned and the inside of the case and the primer pocket will look like new brass. Of course you're talking about $250 for the complete set up, so that makes the hand pocket cleaner look a lot better.

        I'd get all 4 and then decide for yourself which ones you want to keep using.

          Forgot to mention that the tools you reference were for SMALL primer holes only. If you shot large rifle or pistol you'll need a set for them also.

            The flash holes are the same as far as I know. I use Lyman as well as Sinclair . I debut & uniform with one tool the .22's have to be done before sizing. I believe this is one place you control the dimensions. it's a good idea to cut the depth for consistent ignition & to be sure you get that primer below the base of the case for auto loaders. I use the Lyman reamer to cut the crimp out also.

                The primer pocket uniformer cutters on my RCBS do not cut anything but the bottom edge, where it is rounded from the punch forming operation. The idea is to make sure the primer seats fully in the pocket. The sides do not get cut.

                  Do yourself a favor and just buy the RCBS or Lyman case prep center. I got the Lyman as it has more of the tools with it and you do not need to buy them seperate. I like it. Do not use all the hand tools I have anymore.

                  You may want to buy the long inside flash hole deburring hand tool for rifle brass. I have both RCBS and Lyman. Prefer the Lyman since I do not have to buy a bunch of collars for it and it works on all brass.

                  You do not NEED to have any of the tools except a case mouth chamfer tool but it is nice to have them.

                    I like to leave my flash holes alone. Maybe wipe occasionally but usually leave it alone. With that said, there are SOME tools that are nice to have but not needed, but better to have them and not need them then to need them and not have them. These are probably two of those said tools... Also on that list is a 9mm, 45, 380, 40 etc brass trimmer... Yeah Lee sells them, and yeah, you might need them here and there, but the reality is that not always.

                    I would +1 and feel correct in +1 this.
                    I do not have any prep centers but when I get into rifles I might get one. I would imagine that having all of the tools RIGHT THERE in front of you would allow you to use them more versus having to hunt them down in drawers or where ever you hide things...

                        for crimped primers i use a little hornady pocket reamer it is useful no need to true the flash hole as these are not nuclear bullets that require symetrical detonation

                          I used to use them. Never saw a difference. Stopped using them.

                            Yeah, this... ^^

                            Unless you're shooting bench-rest, and ultimate consistency is required, I wouldn't bother.
