For high-performance machining in aluminum alloys.
Adding a necked shank to the M203 design offers
a high-performance tool that permits clearance in
deeper cavities and easier machining against tight
walls. Neck relief and short flute length combine to
increase end mill stability in the cut for more precise
tolerances. Great for work in pockets.
