Are you happy with your recent Grizzly order?
Interesting you ask. Have not used the new set much yet. Our old set ordered in 2007 is still going strong milling 8020 Aluminum for our FIRST Robotics Team. Somehow, the 1/4" mill got lost. We ordered a new set to have some spares. The first time it was used, the 1/4" 4-flute, the most popular mill broke milling Aluminum on our old G8689! That was the first one we broke in 12 years. We haven't tried all of them yet.
