The L.E. Wilson Case Trimmer Uniform Deburring Tool in 45 Degrees is a precision case mouth chamfering attachment designed for reloaders who demand uniformity in their ammunition prep. This deburring tool mounts directly into your Wilson Case Trimmer and focuses exclusively on the inside of the case mouth, removing burrs left behind by the trimming process. The 45-degree angle is the standard choice for most rifle and handgun applications, making it the go-to option for hunters and precision shooters building match-grade loads.

Case mouth deburring is one of those details that separates careful reloaders from rushed ones. When you trim brass to length, you create a burr on the inside edge of the case mouth—one that can interfere with bullet seating and affect concentricity. This Wilson tool eliminates that burr in one quick pass, helping ensure consistent case-to-bullet fit and more predictable ballistics downrange. Because cases are held square to the deburring tool by the trimmer's case holders, you get uniform results every time.

The tool ships with a crank-style handle that's comfortable to operate by hand—perfect for small to medium batch prep work. If you're running larger volume reloading sessions, you can remove the handle and adapt this tool to run with a Sinclair power adaptor (sold separately), letting you power it with a standard drill or rechargeable screwdriver. One note: Wilson recommends using this deburring tool on once-fired or reloaded brass rather than brand new cases.
