T's Case Trimmers was recently started in 2024 to provide an affordable case trimming alternative to like minded reloaders trying to save time and money at the bench. At half the price of the competition and lifetime warranty on the trimmer housing they're hard to beat.
I supply a wide variety of case trimmers in over 30 different calibers. Each one is custom made to order and will be adding more sizes later on down the road.
The sleeves are made from high strength, wear resistant Delrin and the cutters are High Speed Steel endmills. The sleeves will last forever and I'm willing to offer a lifetime warranty on them. The endmills last about 1000+ cases and can be changed out for carbide or replaced with most 3/8 endmills (2 1/2 OAL) that range from only a few bucks up to $20+ for carbide which will almost last forever.
They're capable of trimming by hand but designed to be used in a cordless drill or drill press for fastest results. Any common household drill with a 3/8 chuck or larger will work.
They're easily adjusted by loosening the set screw at the top which allows the cutter to be pushed in or out to set trim length. If you ever need to set it, I recommend starting with an in tolerance brass cartridge for the size trimmer you're using. Insert it into the sleeve until it seats at the shoulder and push the endmill down until it touches the cartridge and then tighten down the set screw. Double check to make sure the endmill didn't shift after tightening since the screw tends to pull it up. Use calipers/verniers for precise adjustments and may need pliers if the endmill is tight.
They'll be set to trim in tolerance to SAMMI specs before being shipped out but advise to go light on the first trim and double check case length regularly.
I also advise cleaning the inside trimmer on the cartridge side with a Q-tip or paper towel after every use and inspect for stuck brass chips to avoid variation or inconsistencies.
If flying brass chips are a problem you can tape over the holes and they'll fall out the bottom. To avoid chip build up just tap it out every now and then.
I also offer the service of making custom size trimmers. If you have a caliber that's not on the list and you'd like a trimmer made for it just email me and I'll get you hooked up with a quote.
