Tool includes: 6 7/8" blade. However 6 1/2" blade also work fine with this circular saw. Metal Cutting Saw, 6320-20, cuts all types of metals such as uni-strut, galvanized pipe, metal studs and black pipe, as well as Hardi-Plank and Durock materials. The saw uses a standard 5/8 in. arbor and has a 2-1/8 in. maximum depth of cut. The blade spins at 3,200 RPM and has an electric brake for quick, repetitive cutting. The clear guard provides an excellent line of sight for cutting and the rugged construction provides long, trouble-free operation.

Metal’s no challenge for this little Milwaukee brute, slicing quickly through everything we put it to: unhardened ferrous metal, non-ferrous metal, plastics and cement board. Power is plentiful, with an 18-volt battery juicing the blade’s 3,200 rpm. We were surprised at how quickly the electric brake halts the blade, too: In our very unscientific test, it was about a second and a half, great for repetitive cuts and even more important for safety. The blade guard is clear, and you do get a great sightline because of it, but it is plastic, and we didn’t want to take our chances slamming it around the warehouse to see what kind of impact it would withstand. A little care is a small price for a much-improved view, we think. It’s lighter than we expected by the rugged look of it, so it handles beautifully, and the ergonomic D-handle grip feels great. If you’re in plumbing, construction, maintenance or even fire and rescue, you ought to have this saw.--Kris Jensen-Van Heste
