This is the best metal cutting saw I have ever used. I cut 1/4" diamond plate and it cut right threw. My only concern with the saw is that it has a 20mm arbor hole. It is very difficult to find metal cutting blades with a 20mm hole. If Amazon is going to sell the saw, they should have the blade to fit the saw but they don't. The blade is Model #12840. I found the blade by going to Porter Cable's website and looking up a dealer that handled that blade. ( TOOLSFORLSS HAS THE 20mm BLADE )

WOW!! What a saw.
br / I am a carpenter in Chicagoland, and we use this saw for cutting various metals, from doors and frames to metal studs and everything in between. The ease and speed when cutting metal studs has to be seen to be believed. It cuts 16 gauge 6' metal studs (2 at a time) like it is cutting wood.
br / There is a learning curve to using it but its not long. I would say after about 4-5 cuts you should have it mastered. Learning to cut at the right speed and amount of pressure is very important. Cutting too fast and too hard will dull the blade pretty fast. ( I have a dull blade that an apprentice can attest to that proves the point.)

br / Just keep in mind that you want to see minimal sparking from the blade when cutting and it should sound like it is just shearing through the metal with ease. When the blade gets dull you will notice it takes a greater amount of effort to push the saw through the work, and the noise is very loud, kind of like what it would sound like if you were cutting a metal stud with a regular saw and regular carbide blade.

br / And another note , go for the MK MORSE metal devil blades, for replacements, 20 mm arbor!!!! http://www.metaldevil.com/index.html

THIS IS THE BEST METAL CUTTING PRODUCT PERIOD. I LIKE IT ( FOR CUTTING STRAIGHT LINES ANYWAY )BETTER THEN MY TORCH OR PLASMA CUTTER. CUTS THROUGH 1/4 INCH PLATE LIKE ITS CUTTING WOOD PANELING.
