How to use a Lee Case Trimmer

How to use a Lee Case Trimmer:

At some point your brass will need to be trimmed. Either you have resized the brass a few times, and the case has lengthened in the die. Or you have some range pickup that you resized and want to trim to be safe.

You will need a Lee cutter and lock stud. About $5
Then case length gauges and shell holder of the caliber you wish to trim, another $5
A debur tool, I use the RCBS tool
Finally you will need a cordless drill

Place your lock stud and shell holder in your drill.
Now screw the case length gauge into your cutter.

Chuck a piece of brass into the shell holder.

Slide the cutter and case length gauge into the brass and pull the trigger. Once you feel the resistance on the cutter stop, release the drill’s trigger.

Ok, so now you brass has been trimmed, but you are not done yet. You will need to chamfer and debur the brass. This aids bullet seating, and easy chambering.



A light touch is all it takes. You don’t want to remove too much material.

That’s it! Next I will show you how to swage the primer pockets of once fired military brass.

Lee also makes a tool that works like the recoil starter on your lawn mower.  The case is mounted into the case turner via a self-centering head; then you just do your case trimming, deburring (and polishing if you want), pulling the cord to spin the case.  It works on all caliber cases, using the same shell guides as mentioned above. 

For survivalists, note it does NOT require electricity!  Costs less than a cordless drill, as well.  I like mine and have done thousands of cases with it, with no repairs or problems.
