Lee Precision 90401 Cutter & Lock Stud Large Case Trimmer Kit

The Lee Precision 90401 Cutter & Lock Stud transforms case preparation from tedious chore into precise operation. This large case trimmer attachment delivers consistent results across magnum rifle cartridges and large capacity cases that standard trimmers struggle to handle.

What Makes This Different

Unlike basic case trimmers that require constant adjustment, the Lee 90401 features a self-centering cutter design that maintains perpendicular cuts automatically. The lock stud mechanism eliminates case slippage during trimming operations, while the hardened steel construction handles high-volume reloading sessions without dulling. Standard trimmers often produce uneven case mouths on larger cartridges, but this system maintains consistent trim length within 0.001 inches.

Key Features

• Hardened steel cutter blade maintains sharp edge through thousands of cases
• Self-centering design ensures perpendicular cuts on all case types
• Lock stud mechanism prevents case movement during trimming operation
• Compatible with Lee Case Length Gauge and Shell Holder system
• Handles large magnum cases from .300 Winchester Magnum to .338 Lapua
• Precision-ground cutting surfaces deliver consistent trim lengths
• Quick-change design allows rapid cutter replacement when needed

Reloaders processing high-volume batches appreciate the consistent performance across extended trimming sessions. The system excels with thick-walled magnum cases that bind in standard trimmers, maintaining smooth operation even on work-hardened brass. Competition shooters rely on the precise case mouth preparation for consistent bullet seating and chamber fit. The lock stud prevents the case rotation that creates uneven trim lengths in conventional designs.
