A proper chamfer and deburr job is one of those case prep steps that separates careful reloaders from rushed ones. The Redding .17 to .45 Cal Chamfer/Deburring Tool handles both the inside and outside edges of your case mouth with a double-ended design that works across nearly every rifle and handgun caliber you're likely to reload. Whether you've just trimmed brass or neck-turned it, this tool cleans up the burrs that can interfere with bullet seating, case integrity, and overall ammunition consistency.

The tool features standard 45-degree flutes on both ends—one for the inside diameter and one for the outside—so you get two functions in a single compact implement. Its caliber range from .17 to .45 means a single tool covers everything from precision rimfire rounds through full-house magnum rifle loads and heavyweight pistol ammunition. That's less clutter on your reloading bench and one fewer tool to track.

For hands-on control during smaller batches, you can use it freehand or in a standard reloading press setup. If you're processing volume, the Redding tool is compatible with the Sinclair Deburring Tools Holder (sold separately), which lets you chuck it into a power drill or screwdriver for faster batch work. Whichever method you choose, consistent case mouth prep means better bullet fit and more reliable ignition downrange.
