The Lastest version of our Model 1000 flash hole deburring tool features stainless steel construction and chip clearance slots which alleviate the tendency of the tool to collect chips in the end of the cutting shaft. This tool is inserted in the case mouth and uses the web of the case as a safety stop. A couple of turns will remove any burrs and leave a small chamfer on the inside edge of the flash hole. Flash hole deburring is a one-time operation. Since variations of case length do not affect the use of this tool, flash hole deburring is most easily performed on brand new brass without trimming.
This tool is available as the 05-1000 standard Generation II flash hole tool which consists of the cutting shaft and the tapered guide. For handloaders who perfer 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. For handloaders who already own this or our previous Model 1000 Flash Hole Deburring Tool the large Sinclair handle is available separately as the 05-1320.
