Metal Cutting Circular Saw Blades
Tenryu Steel-Pro was the original, IIRC. Then there was Morse Metal
Devil, and Mashusita. Now Freud, Lenox, Milwaukee, etc offer them. Are there any differences between them? Has anybody used more than one brand & have a preference? Thanks, Bob |

Metal Cutting Circular Saw Blades
Bob, I installed Decra (rock covered metal) shingles on my house in 2008.
Due to availability I purchased a lenox 7" blade with as many teeth as I could find at Lowes. The shingles are 26 guage zinc coated steel with the same stone used on a standard shingle, sintered (I presume) in place in the zinc. About twenty squares (100 square ft) of shingles were used and a good fourth of them or so had to be crosscut (14" or so). I used a sled on my shopsmith tablesaw and that way, I used the variable speed to get about 4000 rpm or so. No lubricant was used other than wd-40 to keep the sled moving freely. I bought two blades but the first one did the whole job.........but there was not much left of it. I can look up the teeth on the blade if you need me too, but I think it was around 60 teeth or more. Thinner the metal more teeth needed. Goggles, full faceshield, leather gloves etc all recommended. Only blade I have used and I know it is apples and oranges cuz you are problably cutting thicker stock. Think 26 guage x 2 with one side being stone embedded by zinc. I think the blade was $50 or so. Cheap when you think about how many pairs of tin snips tha Decra would have ate up. :-) Hope this helps. Good luck Lyndell "Bob Engelhardt" wrote in message ...

That was long before they made metal cutting metal circular blades though I think (18-19 years ago). Lots of brands have gone down hill since then, but I never heard that about Lennox. |

Thanks, Bob Interesting product, but I'm a bit skeptical about performance vs. regular asphalt shingles. According to their website, the stone is bonded to the steel with an acrylic basecoat: http://www.decra.com/about-us/company-history In hot weather, I'd be worried about the basecoat adhesion with expansion and contraction of the metal. Additionally, in cold climates, I'd be worried about the stone layer soaking up moisture, freezing and cracking. |

Additionally, in cold climates, I'd be worried about the stone layer soaking up moisture, freezing and cracking. So far so good. No separation that I can tell. There has not been any areas that need touching up.......though I have a kit to do so. I see almost no granules of stone in the gutter like I always had with the shingles.......so in three years so far it is staying put. I am middle aged , so if it last 50 years like they claim it will be my last roof. :-) One other benefit is the shingles cool off quickly as soon as the sun goes down, where standard shingles stay hot for hours. It is not real cost effective though. Probably three times the cost of a normal roof with me doing it myself. Would be very costly to have installed by professionals. Lyndell |

The death of any of them is to not maintain a dead true cut line so it would be difficult to suggest a brand and your experience might be much different than mine. Control the speed and control the cut line. My last two have been Morse and I will continue to buy them unless something changes mostly based on supplier. -- ___________________________________ Keep the whole world singing . . . Dan G |

Thanks - I'm beginning to think that I have been too careless in my control of the cut. Thanks also on the brand feedback. I have Morse (bought by price) & I'm glad to know that at least they are not significantly worse than others. Bob |
