These tools are designed to ream flash holes to specific diameters rather than debur. The handloader addresses three issues when using this tool.
1) It enlarges the holes just enough for the die maker’s decapping pins to go through without getting stuck.
2) It removes any burrs left in the flash hole during manufacturing.
3) Each flash hole will be exactly the same size ensuring uniform ignition.
This three-piece tools have a stainless steel guide that centers the reamer in the primer pocket, a knurled stainless steel handle.
