Sinclair International .22 Cal/.243 Caliber Universal Flash Hole Deburring Tool w/Handle

The latest version of our model 1000 flash hole deburring tool features stainless steel construction and chip clearance slots, which reduce the tendency of the tool to accumulate chips at the end of the cutting shaft. This tool is inserted into the case mouth and utilizes the web of the case as a safety stop. A few turns will effectively remove any burrs and create a small chamfer on the inside edge of the flash hole. Flash hole deburring is a one-time operation. Since variations in case length do not impact the use of this tool, flash hole deburring is most efficiently performed on brand new brass without trimming. This tool is available as the 05-1000 standard Generation II flash hole tool, which includes the cutting shaft and the tapered guide. For handloaders who prefer a large, comfortable handle, this tool is also available as the 05-1255, which includes the Sinclair large grip handle found on many of our other tools.
