What Makes a Good Case Trimmer?

There are a few things to look for in a case trimmer, to decide if it's the love of your gun's life or not.

What's The Cutter Made Of?

As the main function of a case trimmer is to trim, or cut, then the blade material is the first thing we should examine.

Some brands make case trimmers with a basic steel cutter, which might get the job done, but won't be satisfying.

Above that, a high-speed steel cutter can do a better job, since it can last you a long time compared to the basic stell cutter.

With that blessing, only a carbide cutter should win your heart. In comparison with steel, carbide is much harder and will stay sharp much longer.

Are The Blades Easy to Replace?

Ease of replacement is another factor that you should examine, regarding the cutter blades of a trimmer.

As the blade wears out over time, buying a cutter and replace it will be a much economical option, and it can be done with ease.

Is It Powered, or Manual?

Manual trimmers have a hand crank that turns the cutter. At a lower price point, they tend to bring you more value for the money.

Some manual trimmers have won a top-rated place in many trimmer ranking lists. This is because their quality stays, or even improves, over time.

Powered trimmers have an electric motor that power the cutter. It is useful for users with outstandingly high volume case rep, however, is not needed for the single gun user.

A seasoned gun owner knows that a case is to be trimmed after a few uses. Each time they trim, they can increase the accuracy and consistency of their rounds.

From there, we've known what a good case trimmer can do for us, and what characteristics the best items should have.

Now, let's move on to the long-awaited best 3 case trimmers of 2020 editors' choices.
