Hornady 050172 Lock-N-Load 6-Blade ID Chamfer Tool Multi-Caliber

The Hornady Lock-N-Load 6-Blade Inside Diameter Chamfer Tool (model 050172) is a precision case-prep accessory designed to chamfer the inside edge of new cartridge cases, preparing them for smooth, consistent bullet seating during reloading.

Built around a 6-blade cutter head, this chamfer tool covers multi-caliber use from 17 Cal through 45 Cal, making it a versatile single-tool solution for handloaders working across a wide range of common rifle and pistol cartridge cases. The cutting head is constructed from metal for repeatable chamfers case after case.

This tool threads directly onto Hornady's Lock-N-Load Quick Change Hand Tool via the standard 8-32 thread, allowing case-prep cutters to be swapped in seconds without changing handles - keeping your reloading workflow organized and fast at the bench.

Adding this Hornady case prep chamfer to your setup delivers clean, uniform case mouths - a small but essential step in producing accurate handloads.
