RCBS 88146 Flash Hole Deburring Tool for 6mm and .243 Caliber Cases

The RCBS 88146 Flash Hole Deburring Tool is designed to help handloaders remove manufacturing burrs from the inside of flash holes in 6mm and .243 caliber cases. These burrs can contribute to inconsistent ignition by interfering with the passage of the primer flame. By cleaning the flash hole, this tool supports more uniform case preparation and consistent reloading practices. It is a practical addition to a case-preparation setup for reloaders who value repeatable results and careful brass maintenance.
The tool features a self-centering pilot collar that helps locate the flash hole quickly and maintain proper alignment during use. An adjustable stop allows the user to control the cutting depth, helping prevent the removal of excessive brass while producing a clean, consistent result. This design makes the deburring process straightforward and efficient, whether preparing a small batch of cases or processing brass as part of a regular reloading routine. The included case pilot stop further supports reliable positioning for compatible cases.
The RCBS 88146 combines a comfortable plastic handle with a durable steel cutter for dependable case preparation. Its green finish with black accents provides the recognizable RCBS appearance, while the compact hand tool is easy to use at a reloading bench and simple to store with other preparation equipment. Built specifically for 6mm and .243 caliber cases, it provides a focused solution for flash-hole deburring without unnecessary adjustments or complicated operation. Use it as part of a complete case-preparation process to help maintain clean, properly prepared brass.
