Product Overview

DIABLOs new Steel Demon Cermet saw blade series is redefining metal cutting and the jobsite, by introducing safer, exclusive innovation that allows users to cut both mild and stainless steels for up to 40X longer life versus standard carbide-tipped metal cutting saw blades. The specially formulated Cermet (Ceramic and Metallic blend) teeth provide high heat tolerances and increased hardness for superior wear and ultimate cutting life. Featuring a special Triple Chip Grind and Perma-Shield coating, these blades slice through the toughest of metals to produce precise cuts and burr-free finishes that require no rework. The thin-kerf body and advanced laser cut anti-vibration stabilizer vents reduce vibration and noise to allow the blades to quickly shear through metal with ease and accuracy. The ability to cut through both mild and stainless steel eliminates the need for individually dedicated saw blades, offering a 1-blade solution for ultimate metal cutting performance and unmatched value story, forever changing the metal cutting industry.
  • Cermet (ceramic and metallic blend) teeth provide a high heat tolerance and increased hardness for superior wear and ultimate cutting life, lasting up to 40X longer than standard carbide metal cutting saw blades
  • Triple chip tooth design provides burr-free finishes that require no-rework and longer cutting life
  • Advanced laser cut stabilizer vents trap noise and vibration for maximum stability, keeping the blade cool for straight, accurate cuts in metal cutting applications
  • Tri-metal shock resistant brazing, a 3-metal brazing system, allows cermet teeth to withstand extreme impact for maximum durability
  • Laser cut thin kerf design provides less resistance and heat build-up for ease of cut, accuracy and long cutting life in metal cutting applications
  • Perma-Shield non-stick coating resists heat build-up by protecting the blade against gumming and corrosion
  • Laser cut arbor reduces vibration and premature wear for accurate blade rotation when in use on the saw
  • Cuts 1/16 in. to 1/4 in. wall thickness in steel studs, angle iron, flat bar, channel, EMT conduit
  • Cuts 1/16 in. to 1/4 in. wall thickness in plate and bar stock
  • Cuts 1/4 in. to 1 in. Dia threaded rod

The blade was used to cut screen rail using a low cost miter saw. Neat miter cuts of the thin metal profiles could be attained by moving the blade very slowly through the pieces, but given the cross section of the rails they still cut quickly. Impatience caused the thin profiles to bend and left burrs.

Don’t use on bamboo engineered flooring
Took it back after three test cuts using a brand new DeWalt miter saw. Even when going slow on bamboo engineered flooring it rips and jars the fibers from the board. Yes I waited until the motor was at nominal speed. For $99 bucks I expect a clean cut

    I used this blade to cut 3/8 inch mild steel with my circular saw. I was very impressed with the way it cut through steel as easily as if it were wood. Very true cuts with very little in the way of ragged edges left behind. I highly recommend the Diablo for cutting mild steel.

    Success Under Harsh Conditions
    I bought this blade as an experiment. I need to section up a piece of 2” thick mild steel and figured I would give this a shot to see how far it gets. Using it in a 2.5HP Skil saw I was able to get 3” or 4” into the cut before it started losing traction. Considering it is billed as a blade for 1/4” thick steel I’d say it was a good success. Once the blade cools down I’ll give it another go.

      Love this blade - Use it for my circular saw and Miter saw.
      I always used to buy cheap blades and throw them away but after using one of these i will never go back to the cheap blades, I'll just wait until these go on sale here and there. I have the Kobalt 7-1/4 sliding miter saw and i used this blade on it... using the stock blade it was OK and cut fine but with this blade it cuts sooooo smooth it's ridiculous.

              Ended up buying the $17 competitor.
              I bought this blade and it cut about 6in of concrete. I thought I got a dud so I bought two more and got about 10 feet cut out of the three blades. Went and bought the $17 competitors blade and cut about 40 ft and finished the cut this Diablo couldn't. Don't waste your time. Pictures is how long the first blade lasted.

                Does the job but didn't last as long as expected
                I bought this blade yesterday to cut down a piece of galvanized 1/4" thick steel diamond plate. The total cut length I needed to make was 19ft (3x6ft cuts and a 1x1ft cut). It cut well for the first 8ft or so, after that progress started to noticeably slow down. I stopped at 14ft total cut length as not only did progress become painfully slow but the blade started pulling to the right. Visual inspection of the blade at that point revealed that one tooth had lost its tip (see photo). So I'll need to buy another blade to finish this job. The chips are hot and sharp, glad I wore my welding leathers ! I have not used any other brand of steel cutting circular saw blade so I cannot comment on how its durability compares, but I was surprised to need a second blade to complete this job. However, it is the one steel cutting blade that Home Depot stores stock, it did get that job done (all be it with having to purchase a second blade) and the cut edge was more presentable than if I'd used an abrasive blade or sawzall. So on that basis I recommend it. I hope the above info will give others an idea of what performance to expect.

                  Clean cut, quicker than abrasive wheel
                  I was using a standard abrasive cut off wheel and it is so slow with wide, rough cuts. The D0748CFA is amazing! it cut smooth with little effort. I moved the blade through .125 1.5" square tubing slow and steady and it worked perfectly. I did not know a saw blade could cut metal like it cuts wood. I will never go back. also did 45 deg cuts smooth edge for quick an easy welding. Making a railing. This is the blade to use!

                    FANTASTIC SAW BLADE - I picked one of these up for ripping sheets of 3/4" mdf - I cut close to 300 linear feet and the blade still looks brand new. With my M18 Circular Saw I couldn't push fast enough to slow the blade and inhibit performance. I couldn't believe how quickly this blade cut through the mdf and how little effort it took. I've also cut 3/4 plywood, 5mm underlayment, and solid walnut, all with great results. The mdf had no tearout at all

                    I'm cutting fiber cement boards for my 700 sq ft cottage and even though the diablo blade is not meant for this,it's doing a great job so far. I'm halfway there(using 230 12ft boards) and it's still going on strong. Even if i have to buy another blade to finish the job,it's only $9 that I'll spend. Beats buying a cement cutting blade well over $50! Will definitely be buying this type blade for all my construction use.

                    I used this blade to install 270 sq ft of Pergo Outlast flooring in my Basement. It made a clean cut, even with the padding on the back of the Pergo. A much better option than a board cutter ( I tried that first). Used it to cut laminate moulding as well.
