Works But…
I used this and the facing tool to flush cut and crown a couple 1911 barrels and it worked great. Only caveat is despite using plenty of lubricant and other precautions, I still got chatter marks. So, don’t be surprised if you find yourself investing in a lapping tool as well.
Works for 9mm Luger.
This is the one for 9mm Luger. Not mentioned in the description. Super sharp. Just a gentle push cuts the rough edges left by rifling cutting. A little abrasive lapping after this cutting leaves a good looking smooth muzzle. Does a great job cleaning up cheap Glock aftermarket barrels. Be sure to hold the barrel firmly in a vise while cutting and lapping.
Accomplished what I needed
Needed to chamfer cylinder for model 610 revolver. Did this. Recommend getting a polishing attachment to finish surfaces with this tool.
Crown Cutter and Brass Pilot Works Fine!
Bought a used rifle that had a damaged muzzle crown, both from hamfisted cleaning rod abuse and from rust. I used this tool set to cut a new crown, and it cut well and removed quite a lot of metal, which was necessary. The rifle, a 30-06, now shoots sub-MOA. Be careful to follow directions exactly, go slow and gently, and used lots of oil, and clean the cutter after every few turns. THAT is a must, or you can get metal cuttings down in the bore alongside the brass pilot. The pilot cannot damage your bore, but those metal shavings can scratch the rifling lands. With careful use, this tool assembly can restore your rifle's, or pistol's, accuracy.
Detail matters
Shooting performance is the sum of many small details. This tool is essential for a clean muzzle cut.
Worked Great
Followed the instructions and it cut the crown perfectly.
Perfect fit for Ruger rimfire barrels
Called the Brownells tech and asked what size I should get for my 10/22 Ruger. They couldn't tell me from experience and suggested I slug my barrel. (you want the largest that will fit to eliminate chatter) Brownells offers 3 sizes for the 22 rimfire, .210, .211 and this .215. Not knowing which size, I tried every round object I had on hand and finally came up with a screw shank that mic'd exactly .215-perfect! So that's what I ordered. It only took maybe 3 revolutions total to get the bevel I was looking for. Oiled it up well, a couple light turns (could feel it cutting), pulled it out, cleared the chips with spray degreaser, re-oiled and one last LIGHT pass did it!
Should work, but doesn't
I've ordered 79 degree and 90 degree cutter from Brownell's, and have had great success with them. But for whatever reason, I've had no luck with 45 degree cutter. I literally cannot get it to cut in any way whatsoever, either by hand or drill press. The Allen screw to hold the pilot stripped on the first use as well, making it impossible to secure the pilot to the cutter. I have no idea how but 45 degree cutter is not in the same league as the other two I've bought.
