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 and either a .0625” or .081” reamer for small or standard flash holes.

Brownells USA Not a complete function 25/11/2015

With un-crimped good brass it works well. The existing flash hole needs to be well centered and pretty close to 0.080 for this to work. It's only designed to remove a few thousandths on already decent flash holes. It does have 4 cutting edges with good cleanout grooves for the small size so its hard to clog it and damage the hole but it still doesn't deburr or taper the inside edge. The deburr tool I use almost does this tools job as well but because it cuts to 0.081 it still has a purpose. I would suggest using this reamer first and deburring second to insure clean uniform flash holes. I have used this reamer and my deburring tool on match grade custom brass of every brand and they both still further refined even the most expensive offerings.

Definitely recommended

Brownells USA Worked perfectly 15/10/2015

Received reamer and used it on 250 cases initially without a flaw, worked perfectly. Additionally, it make evident several cases in which the primer pockets were not straight. I checked and my gun screwdriver set had an Allen key that fit perfectly should it ever need to be taken apart.
