Product description
Mark 7 Power Trim Xpress -
Trim Cases with Lightning Speed!
Works on most Progressive, Automated, Turret or Single Station Presses
Mark 7's new Power Trim Xpress case trimmer will tackle the toughest commercial trimming jobs yet is priced to fit any reloader's budget. The trimmer features a powerful variable speed DC motor, yet it is also a slim design that takes up minimal room - only one die station on progressive presses, unlike other trimmer that take up two or three stations!
The trimmer will speed through standard trim jobs and also easily handle cartridge conversions such as 223 to 300 Blackout.
The Power Trim Xpress accepts standard trim dies and is equipped with a vacuum manifold to cleanly evacuate chips. In addition, the trimmer comes with a long-lasting carbide cutter. (Note: some photos show additional items not included with product. Product includes: Trimmer, vacuum manifold, motor, power cord and mounting hardware.)

Reviews
I read some pretty bad reviews about this item before purchasing. There were several that stated it either "chewed up brass" or "quit working after trimming several cases". The day it arrived, I trimmed and processed about 800 5.56x45 cases without a single issue.<br />
I am convinced the reviews stating it damaged brass were operator error, for the most part. The tool speed is infinitely variable in its range, and I think those people were running the speed too low. The instructions on Mark 7s website (none are included with the unit) say to start out between 7 and 8 and if you get chatter to slow the speed down. This is an error in the instructions. If you get chatter, you need to speed the tool up, not down. Basically the tool cannot keep up with the feed rate, so slowing it down just makes it worse. I started at 8 and when I got chatter, I did as the instructions said and turned it down to 7, and as expected, it was worse. When I turned the tool to 9, it trimmed the brass smoothly and quickly. It really gives a pretty clean cut. <br />
The only con I really have is that Mark 7 states that it only uses one die station on a progressive press. This isn't entirely true. The trimmer itself only uses one station, but with the vacuum collar installed you won't be able to place most dies on either side of it. Not a big deal on my Dillon 750, as I only have a SB sizing die in station 1, a Swage It swager in 2 (replacing the primer system) and the trimmer in station 4. This setup allows me to completely process military 5.56 brass in one trip through the press.
