outside mouth de-burring tool

[nilebartram]

I have a RCBS trimmate and I wonder is there a after market outside mouth deburring attachment that will fit it. I can not seem to find a RCBS one.

Have you looked for an RCBS 3 way trimmer head? esay to convert to other calibers by changing the pilot, they make special pilots for them. Buy one assy in one caliber, add pilots as req'd.

The RCBS Trim Pro 3-Way Cutter has a three-blade head configuration that trims to length, inside blades chamfer the case while an outside blade deburrs it.

8/32 ... Most any brand will fit. I think mine is Hornady
Maybe Some are for short stubby and some are for long skinny ... Not real sure on that been so long since I've actually looked for one.

I have a Trim-Pro II and got the Three-way cutter Head . Bit of a PITA to get the Outside case neck cutter set , in conjunction with the depth trimmer , but once that is accomplished , you're good to go . It's well worth the asking price .

I don't know how many of you find this bothersome but I do. I've tried several conventional, outside chamfer tools but none of them seem to be acute enough. They remove the front part of the burr but not the most rearward part. Looking at my Lyman Case Prep Multi-Tool, the inside tool has a long VLD taper but the outside tool is much more obtuse, The results make me feel obtuse as well. The one that Danny-L linked looks promising but I'm tired of throwing money after what appears to me as a common design shortcoming. Of course, I just replaced my Trim Pro with the Lyman Carbide trimmer which is very nice I might add. If I got that RCBS Trim Mate Carbide Chamfer tool, would that fit my older Trim Pro? The model with the different shell plates, for which I have many sizes of. The threaded shank looks a lot smaller in diameter. Besides, I'm miffed at RCBS' refusal to manufacture the replacement Carbide cutter for my Trim Pro that they used to sell, I'm assuming because they want you to buy their newer product. The non-Carbide cutters get dull faster than I care for, so I went with the Lyman as it was the only one I could find with a Carbide cutter option..

I use 6"×1" scotch Brite grey wheel mounted in 6" grinder. Polish off the burr leave a nice small radius...fast, and easy. You can even polish off the neck and shoulder of carbon and reload without tumbling. Just spray lube, size, wipe off lube on towel...reload.

The Trim-Pro 3 way cutter from RCBS as championed by Jones 209 in post #2 is an excellent tool. It assures perfect uniformity in three operations: case length sizing, ID chamfering and OD chamfering - all in one step. Be warned it is tedious to set up. Once that is accomplished, though, it holds those settings forever. Because of that, you would be wise to purchase one tor every high-volume caliber you reload.

I actually ordered one on Wednesday evening. Shipped today. Hopefully it is acute enough to get all of the mouth peen, not just the front part like my other ones that I've tried. if not, I'll feel like a $62.00 poorer fool.

Last night I timed myself. It took 15 to 20 seconds to, clean the primer pocket, chamfer the outside of the neck, deburr the inside and bevel, and this is with LC 7.56 brass. 3 to 4 brass in a minute is not bad. The RCBS carbide chamfering tool is a game changer. I always hated this part of prepping brass.
