Things to consider when buying case trimmers

Reloading is a hobby to many. However, with a poor quality trimmer, the experience can be ruined. A quality trimming machine will not only ensure you trim your cases with high precision but also save your money in the long run.
Here are important factors to be on the lookout each time you are shopping for a case trimmer. Just take a look!


Speed is one of the critical features that should be given much weight when it comes to selecting a trimming machine. A low case trimmer will consume much of your time and spoil the fun. A trimming lathe should speed things up.


Trimming lathe cutters need to be sharp to be able to trim your cases faster. Steel cutters will call for replacements occasionally unlike carbide cutters which last a lifetime.

Ease of use

Trimming cases should not be a complicated process. A trimming lathe with simple design will be easy to operate and save your time.

Additional features

Chamfering and deburring are required after trimming your cases to make them smoother. Using your trimming lathe along with polishers helps remove any debris at the cartridge mouth down to its internal chamber hence extending your cartridge lifespan.
A perfectly cleaned shell helps improve the accuracy.


Not every trimmer in the market will trim your cases with precision. A good trimming lathe should allow you to adjust your settings and trim cases with accuracy. Try to check out how the machine has been reviewed by customers who gave it a try before purchasing.

Trimming needs

Every trimming lathe has trimming size length. Your case caliber should fuel the type of trimmer to choose.


Almost every trimmer manufacturer has backed their machines with warranty periods. A more extended warranty period keeps you covered for longer should the device fail. Read all the term and conditions and understand what the warranty cover and for how long.


Case trimmers may require you to use some accessories. While some come equipped with all the accessories needed during the trimming process, others are not.
This means that you will spend extra money on purchasing the accessories. To save the cost, always consider selecting machines which have accessories included in the package. However, if the trimmer possesses special features, then it may not be a good idea to go for another trimmer that does not match your needs.


Reloading is economical, and price should not be so important since you will save money in the long run. Trimmer may vary in price depending on their quality and features. However, it’s always a good idea to stick to your budget.

Power upgradability

Manual cranking can be irritating and tiresome especially when trimming a large number of cases. Powering your trimming lathe can increase the speed and allow you to handle a large volume of rifle cases.

Care and maintenance of case trimmers

Every machine requires proper maintenance and trimming lathes are not an exception. Though there is no much required to keep your trimmer in good physical shape, you will be required to carry out simple maintenance to minimize wear and tear levels.
If you have no idea how you can extend your trimmer lifespan, here is how to achieve it much faster.
Replace your cutters or sharpen them occasionally to ensure you get clean cuts
Oil your crank handle and the cutter shaft
Keep your cutter clean by removing any shavings or chips to facilitate clean cuts

What makes a good case trimmer?

  • A good case trimmer should be easy to operate and maintain
  • A good case trimmer should trim cases with precision
  •  A great case trimmer should trim cases quickly

Final Verdict

You can never go wrong with a high-quality case trimming lathe. The convenience and efficiency these machine offers are incomparable to none. You can now trim your cases and save money that would have been used to buy new ammunition.
However, each trimming lathe is designed to perform differently. Though these machines may differ regarding size, design, weight, speed, and performance the best case trimmer should be easy to operate, accept various cutting heads, easy to adjust, fast, and above all deliver clean cuts.
