RCBS 88147 Flash Hole Deburring Tool 7mm / 284 Caliber

The RCBS 88147 Flash Hole Deburring Tool is a precision 7mm and 284 caliber case-prep accessory built to remove burrs from the flash hole of freshly sized brass. This handy tool automatically locates the flash hole and quickly removes any burrs left from manufacturing or resizing, helping ensure clean, consistent ignition when reloading.

Built around a steel cutter paired with a green and black plastic handle, the RCBS 88147 is part of RCBS's dedicated flash hole deburring line. The self-centering pilot seats in the case mouth, guiding the cutter squarely into the flash hole so burrs are removed without over-cutting the brass. This attention to detail helps produce more uniform primer seating and reliable primer ignition across a batch of prepared cases.

The RCBS 88147 is intended for use on 7mm and 284 caliber cases as part of standard case preparation. It is a caliber-specific tool, with matching pilot stops available from RCBS to prevent removing too much material from the case head, making it an essential step in quality case prep for any reloader working with these case sizes.
