Milwaukee 6390-21 Review


The Milwaukee 6390-21 Tilt-Lok Circular Saw is little powerhouse, with a 5,800 rpm, 15-amp, 3 1/4 horsepower motor.  This allows it to easily cut through most materials without breaking a sweat. The Spindle-lock button makes it very easy to change the blades, and the Tilt-Lok handle adjusts into eight different positions, easily adapting to any cutting job you can throw at it. Considering its powerful motor, the Milwaukee 6390-21 is surprisingly lightweight at just 10.4 pounds – one of the lightest in its class. While being very light, it is still extremely sturdy and durable – truly a testament to Milwaukee’s decades of development and experience constructing high quality power tools. The use of a 22-amp switch and steel Helical gears ensures the Milwaukee 6390-21 circular saw can withstand years of standard wear and tear.
