Just after returning from Milwaukee Pipeline, these arrived in our shop. The Milwaukee 3486-20 is the M12 FUEL Straight Die Grinder, and the 3487-20 is the M12 FUEL Extended Die Grinder. Both of these units have 4 speed modes, delivering up 5,000; 10,000; 15,000; and 20,000 RPM. They also both include dual LED lights for working in those dimly lit areas. The 1/4" safety collet requires loosening twice to remove the bits, but with the spindle lock button, it only require one wrench to loosen. #shoplife #milwaukeetool #mechaniclife
