Derraco Ugly SRT Shoulder Referenced Brass Case Trimmer - Simple

Our review of the Derraco Ugly SRT Gen 2 case trimmer finds it best suited to serious handloaders and gunsmiths who want repeatable, fast case trimming without fuss. The single biggest reason to buy is its combination of precise micro adjustment and rock-solid mechanical feel: the innovative Lock N Adjust ring lets users dial in 0.001' depth changes while the France-made SKF ball bearing and M2AL HSS cutter deliver a smooth, burr-free cut. For anyone who trims regularly and values speed plus consistent trim length, this tool earns its place on the bench.

Key Features

• Precision adjustment: The Lock N Adjust ring allows 1 thou micro adjustment for exact and repeatable trim length without re-zeroing between calibers.
• Smooth operation: A France-made AB SKF deep groove ball bearing press fitted to the main body provides ultra-smooth rotation for consistent cutting action.
• Durable cutter: The M2AL HSS milling blade is very sharp and holds an edge longer, producing clean cuts and reducing the need for deburring.
• Aircraft-grade body: Main body is CNC lathe milled from USA-made 6061 aircraft alloy for rigidity and reliable alignment under use.
• Wear resistant finish: Hard anodized surface gives ceramic-like wear resistance, keeping sliding surfaces smooth and durable over time.
• Includes collet tool: A 304 stainless steel collet removal tool is included for quick changes when swapping collets or calibers.

Who It's For

The Ugly SRT Gen 2 is aimed at precision-minded reloaders, competitive shooters and gunsmiths who trim brass frequently and need tight control of final case length. Its ability to quickly swap calibers with minimal reset and its smooth bearing action make it ideal for moderate to high volume trimming sessions.

Those who should look elsewhere include occasional reloaders who only trim a few cases per year and would prefer a simpler, lower-cost trimmer; also note that buying only a "COLLET ONLY" option does not include the SRT trimmer body, so newcomers should select the correct SRT+NO. XX package to get a complete tool.
