RCBS 90291 Trim Pro 3-Way Cutter .375 Caliber Rifle Case Trimmer

The RCBS 90291 Trim Pro 3-Way Cutter delivers precision case trimming for .375 caliber rifle cartridges with professional-grade accuracy. This specialized cutting head transforms brass preparation from a tedious chore into a streamlined operation that maintains consistent case lengths within ±0.001 inches.

What Makes This Different

Unlike standard single-function trimmers, this 3-way cutter simultaneously trims case length, chamfers the case mouth, and deburrs the flash hole in one smooth operation. The hardened steel construction withstands thousands of cutting cycles while maintaining sharp edges that produce clean, uniform cuts. Standard trimmers require multiple tool changes and separate operations, making this integrated approach significantly more efficient for high-volume reloading.

Key Features

• Precision-ground carbide cutting edges maintain sharpness through extended use
• Three-in-one operation: trims, chamfers, and deburrs in single pass
• Caliber-specific design optimized for .375 rifle cartridge dimensions
• Hardened steel construction rated for 10,000+ cutting cycles
• Compatible with RCBS Trim Pro and Trim Pro 2 case trimmer systems
• Self-centering pilot ensures consistent case mouth geometry
• Quick-change design allows rapid caliber switching during reloading sessions

Competitive shooters and hunters appreciate the consistent case preparation this cutter provides, particularly when working with premium .375 H&H Magnum, .375 Ruger, and .375 Winchester brass. The precise chamfer angle reduces bullet seating force while preventing case mouth damage during loading. Weather-resistant steel construction maintains cutting performance in humid conditions where lesser cutters might dull prematurely.
