Skilsaw states that it's made of titanium carbide which we know lasts about 10 times longer than standard carbide blades. The teeth are sharpened with a 600 Grit diamond wheel, which as Rick Peil states, "makes the 76924 cut smoother than most other 24 tooth blades around".
For increased accuracy, the blade has expansion slots to insure that the blade runs straight and true and also features a clear anti-stick coating to resist friction, heat and binding.
Contractor Dave Schulte, from Schulte & Associates sampled the WormDrive77 blade. "I have installed the new saw blade and used it on my next framing project. The WormDrive77 blade works very well and I really enjoy the fine narrow cuts that the saw blade makes when cutting lumber. Thank you for the free Skill worm-drive blade to try. This should be a great improvement to the industry for faster and more accurate narrow cuts."
John Liselli from Castle Builders of Colorado, LLC had this to say about the Skil WormDrive77 blade: "My name is John Liselli and I am the owner of Castle Builders of Colorado, LLC. I am also the lead carpenter on all of my projects. Recently I was asked to test drive a specialized worm drive saw blade by SKIL during a regular work day. I chose to put it through its paces cutting stair stringers out of 2x12 pine which is one of the tougher jobs a blade can do.
I found the Skil WormDrive 77 to be quite reliable. The blade cut true, was quite durable and remained sharp long after the job was completed. Most impressively I cound that unlike most other "thin Kerf" blades, the Skil WormDrive 77 did not wobble or travel when it heated up during cutting. I was pleased with the Worm Drive 77 and would recommend it highly."
