The Lee Precision 90740 Power Quick Trim Adapter converts manual Lee Value Quick Trim and Deluxe Quick Trim case trimmers into motorized trimming setups. Built with an unpowered mechanical design weighing approximately 45 g (0.10 lbs), the adapter replaces the manual hand crank and connects directly to a standard cordless screwdriver or drill. When installed over a caliber-specific Lee Quick Trim die in a standard 7/8"-14 threaded reloading press, it allows handloaders to rapidly trim cartridge cases to length under power, eliminating repetitive manual rotation during brass preparation.

Key Features

• Motorised Conversion: Replaces the factory manual hand crank to convert case trimming into a power-driven operation using an external cordless tool.
• Standard Hex Drive: Integrates a 1/4-inch hex drive shank compatible with standard cordless screwdriver chucks and low-RPM drill chucks.
• Rapid Brass Processing: Cuts case preparation time by trimming cartridge cases under power in seconds, functioning with Deluxe cutter assemblies to trim, chamfer, and deburr simultaneously.
• Mechanical Adapter Design: Contains no internal motors, batteries, or wiring, eliminating electrical compliance requirements for 240V Australian mains power.

Who is the Lee Precision Power Quick Trim Adapter for?

• High-volume handloaders — eliminates repetitive hand and wrist strain during bulk brass processing by utilizing a standard 1/4-inch hex drive shank to trim rifle and handgun cases under motorized drill power.
• Single-stage press reloaders — integrates motorized case trimming into standard 7/8"-14 threaded reloading presses without requiring dedicated benchtop cutting machines, adding just 45 g of mechanical hardware to the cutter assembly.

Less suitable for: Commercial reloading operations processing thousands of rounds per hour, which require dedicated benchtop motorized case trimmers, or off-grid reloaders without access to cordless power tools, who are better served by standard manual case-length gauge trimmers or manual hand cranks.
