Before now there has never been extended length end mills rigid enough to efficiently machine the mag well from one side. AGT'S New Design has overcome that obstacle! With a simple pilot hole through the middle, you can rough, finish all from one side. Ending up with a perfectly smooth finish all the way down to the bottom of the mag well. No more flipping the lower on the fixture and ugly mismatches and hand blending.
Your end result will be a finely machined lower receiver that you can be proud of!
1/4" diameter, 5/16" shank, End Mill with high performance 3 variable flute geometry, .750" length of cut for rigidity and .10 corner radius for strength, a necked relief reach of 2.700" from end of tool with 4.0" overall length which allows completion of mag well from one side.
