The Hornady Lock-N-Load Neck Turn Tool is a bench-mounted case neck turning lathe engineered to uniform rifle cartridge case neck wall thickness, eliminate neck-shoulder doughnuts, and promote concentric bullet release. Built around a Cam Lock trimmer-style frame made of cast/billet aluminium with steel components, the unit fastens directly to a reloading bench via integrated 1/4-inch mounting holes or C-clamps. The tool operates manually via an integrated spindle or under power assistance by attaching a user-supplied cordless drill or power screwdriver to the hex drive spindle. Because it is an unpowered mechanical unit, it requires no mains power or electrical compliance certifications.

Key Features

• Dual-Mode Micrometer Adjustment: Features a micro-adjustable dial that provides click detents of 0.0005 in (approximately 0.013 mm) per click for controlled depth setting, or a smooth mode without detents for continuous infinite adjustment.
• Included Mandrels: Ships out of the box with four calibre-specific turning mandrels: .22 Cal (0.221"), 6mm (0.240"), 6.5mm (0.262"), and .30 Cal (0.306").
• Hex-Drive Spindle: Allows reloaders to switch between manual turning and high-speed operation using a standard battery-powered drill driver.
• Calibre Expansion Capability: Accommodates optional accessory mandrels to turn brass from .17 Cal (0.172") up to .375 Cal (0.373").
• Benchtop Stability: Solid frame design eliminates flex during turning passes to ensure uniform wall cuts across the entire circumference of the case neck.

Who is the Hornady Lock N Load Neck Turn Tool for?

• Precision target shooters — requires precise brass preparation down to 0.0005 in adjustment increments per click using this bench-mounted case neck turning lathe to eliminate wall variance and ensure concentric bullet release.
• Long-range hunters — relies on a tool system capable of supporting calibres from .17 Cal up to .375 Cal to shave neck-shoulder junction doughnuts and uniform brass for consistent chamber pressures on extended-range hunting cartridges.

Less suitable for: Handloaders processing large-bore cartridges exceeding .375 Cal (such as .40+ or .50 BMG cartridges) or those requiring universal multi-brand shell-holder compatibility, who require dedicated heavy-calibre turning tools or universal cartridge lathes; it is likewise less suitable for reloaders needing a lightweight field setup, who are better served by a compact hand-held turning tool.
