TRIM-IT II CASE TRIMMER Reviews & Ratings

TRIM-IT II will change everything you know about trimming brass. It can trim, chamfer, and deburr virtually any rifle or pistol case. It have a built-in micrometer dial for supremely accurate and consistent cut-length control. You need a TRIM-IT II.

I got this case trimmer in the mail yesterday. This morning I began to assemble it with the .223/5.56 caliber die. Every thing went together fine and the construction was almost flawless. I began to install the caliber die and found that it was so tight that if I was able to install it, I would have difficulty removing it. I examined the area where the die is seated and found the area where the hex set screw had been drilled and tapped had never been smoothed and metal fragments were protruding into the die seating area. I cleaned the area up using a fine small file. The die was still much too tight. I used 600 grit wet or dry paper and went over the entire seating area and then got a nice fit and the die can be easily removed. I might note that it took very little sanding. I then trimmed about a half dozen .223 cases got perfect results. This trimmer is faster than my Redding 2400 but I did use the Redding it to get the case to the exact OAL to set the Trim It II. The trimmer saves extra tedious steps in processing cases. I can find no downside to this trimmer as yet. I am glad I made this purchase.

For the Trimmer that I received in the mail, my only complaint was the highly torqued small allen head screws by the factory. If you study the instructions well on how to adjust the cutting blade and watch how the micrometer changes the cutting depth when you adjust it significantly, it works great. It is a precision instrument and not a toaster, so it takes some paying attention to get it set up right. First, make sure your cases are re-sized the required tolerances for headspacing using a case gauge. Getting the die adjusted "ball park" close to the recommended OAL for the trimmed cartridge, but not quite that short. Second, getting the cutting blade adjusted so it makes a small but visible chamfer in the inside of the trimmed brass. It's a trial and error process to get it right. Do a final adjustment to the micrometer to get your trim depth correct. Once all the allen screws are confirmed torqued down properly (not too much), spool up the drill first, insert firmly, do a half twist, and pull out when the cutter stops cutting.

I have to say that I was eager to get my hands on this . Ordered initially with 223 bearing insert for typical high volume trimming. I have used many trimmers over the years including the Giraud, RCBS 3-way crank trimmer, etc, but what drove me to this was the interchangeable inserts for multiple calipers and run on my lathe. At first it looks and feels like it is made well, but when I got into adjusting it my perception changed. The housing is made of aluminum and the internal threading was rough and is easily damaged. The design allows for the set screw to easily damage the threads if not careful. Speaking of design ... it takes 4 different size hex wrenches to adjust ... not as easy as it should/could be! The trim head adjustment screw head binds on the internal channel and made it extremely difficult to turn ... feeling like you were bottomed out. I watched a few videos of how to adjust prior to using and it seemed straight forward enough in principle (less the 4 different sized wrenches), however the adjustments for chamfer and debur are pretty finicky and the effort to cut along with final quality was not very good in comparison to other trimmers. Lastly the bearing has a tendency to spin and leave marks on the brass. I'm sure there are other experiences that would support a positive experience, but I'm going to stick with my current trimmers.

Very sloppy thread on micrometer body leading to miss-alignment of body to cutter. A fixed body and micrometer adjuster on the cutter may have been a better solution.

Sorry I fell for this! You will ruin more brass than successfuly trimmed. Followed instructions for setting the trim. Too much de-burr, adjusted too much chamfer. Once it's just right it will hold for about 3-4 decent cuts and back to the drawing board. Lack of customer service. I would give it away.

It is hard to adjust. Once adjusted, it is hard to hold the casing or the brass, so it doesn't rotate. It takes longer to trim my cases, even when I use a drill! I won't recommend it. Besides all these problems, or maybe why I had such a hard time making it work, the trimmer I received didn't have a logo on it. It didn't seem like it came from Brownells. Was this trimmer a replica??

This tool has potential. The adjustment is horrible due it having too much slop in the threads that adjust the blade side to side and the slot for that allen screw is slightly tapered making it difficult to turn in small amounts for fine adjustments (head of screw binds in the slot). Can't be precise with adjustments. The blade has a terrible cut. the "V" is so rounded out that it doesn't even chamfer or de-burr since the neck wall is thinner than the rounded 'point' in the V (should I say U?). Since I still need to chamfer and de-burr, what's the point in the cost for the three-way trimmer if it only trims? See the photos (I know some are with the case on the wrong side ..pics are to see roundness vs. neck wall width. This is a Lapua 6.5 Creedmoor case (3x fired) never neck turned. Give it a good blade and the other gripes could be lived with ..Giraud or Gracey is probably worth the extra cash.

Lots of run out and entire housing on 2 out of 3 of mine wobbled even when using an official trim it 2 rechargeable motor. Constantly went out of adjustment and chattered. Only 1 out of 3 that I owned worked decent.
