3/8" CNC CORNCOB FORM RUFFER FOR MILLING THE MAGWELL ON AR15 / AR10 / .308 LOWER RECEIVERS

Part# 38MAG-ROUGHING

AGT's proprietary "F23" coating  for extreme wear resistance and lubricity.

These end mills deliver improved performance,
and set a new benchmark for machining the firing pocket and the mag well.
The combination of our extended length 3/8" rougher and 1/4" finisher is a GAME CHANGER!
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 hole through the middle you can now,
rough and finish from one side, with a perfectly smooth finish all the way down
to the bottom of mag well. No more flipping the lower on the fixture.
No more ugly mismatches and hand blending.
Just a finely machined lower that you can be proud of!

Course Pitch Rougher
High performance variable 3 flute geometry, .750" LOC for rigidity, .030" corner radius for strength, necked relief reach of 2.700" from end of tool with a 6.0" overall length.
