The Frankford Arsenal Universal Precision Case Trimmer (Model: FA-UPCT / Part # 1092514) is a drill-mounted case trimming tool engineered for resized bottleneck rifle brass. Designed to fit standard 3/8-inch or 1/2-inch drill chucks on user-supplied power drills or bench drill presses, the unpowered mechanical attachment indexes directly off the case shoulder. This eliminates the need for separate caliber-specific pilots or shell holders. Using a High-Speed Steel (HSS) cutter paired with a micro-adjustable collar, the tool delivers rapid, repeatable brass trimming across a broad spectrum of rifle calibers.

• Shoulder-Indexing Alignment: Indexes directly off the datum line of full-length sized or shoulder-bumped brass, trimming cases quickly without requiring internal neck pilots.
• Micro-Adjustable Depth: Integrated click-stop collar adjusts cut length in 0.001-inch increments for exact case length consistency.
• Universal Collet System: Supplied with 3 body collets and 6 shoulder stop bushings to accommodate bottleneck cartridges ranging from .17 Remington up to .460 Weatherby Magnum.
• High-Speed Steel Cutter: Durable HSS cutting head maintains edge geometry under repetitive drill-powered operation.
• Drill Integration: Operates via standard cordless drills, corded drills, or bench drill presses with no internal electrical circuitry or mains power requirements.
• Protective Storage: Measures approximately 7 inches in tool length and ships in a molded hard plastic storage case with a total package weight of 1.08 lbs (approx. 0.49 kg).

Who is the Frankford Arsenal Universal Precision Case Trimmer for?

• Precision rifle handloaders — provides depth control in precise 0.001-inch increments using an HSS cutter to ensure consistent overall length across resized bottleneck rifle brass.
• Multi-caliber rifle reloaders — processes diverse bottleneck brass spanning from .17 Remington up to .460 Weatherby Magnum using an included 3-collet and 6-bushing system that eliminates the need for individual caliber-specific shell holders.

Less suitable for: Straight-wall rifle or pistol cartridges (such as .45-70 Gov, .357 Mag, 9mm, or .45 ACP) that lack an index shoulder, as well as cases that have not been full-length sized or shoulder-bumped; these applications require a conventional lathe-style case trimmer.
