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

A firearms manufacturer that specializes in AR15 lower Receivers contacted us to design a set of end mills that would increase their productivity and lower tooling cost."AGT " was up to the task and you will love the results!

AGT'S new line of 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.
Which will allow completion of magwell from one side.
