Cutting metal has never been easier! This Lenox 21889AL120080CT Circular Saw Blade provides quick and efficient cutting while trimming down your expenses at the same time. Its modified TGC (Triple Chip Grind) blades are designed for durability and feature two types of cutting teeth that produce less burr than standard abrasive blades. The FTG and the "trapeze" tooth of this blade alternately give a slanting/sloping cut from the corners, followed by a cut in the middle of the kerf, and a finishing clean cut back on the corners. With this process, the blade doesn't easily get dull, and will retain its sharpness cut after cut. When talking of durability, this saw blade's tip is made of titanium carbide that protects the tip from unnecessary material build-up and corrosion from the heat that can affect its cutting power. The unique pattern of this circular saw blade maintains a clean and precise cut compared to other abrasive blades and greatly reduces burr and snags. When used, this Lenox blade produces less burnt materials as well, reducing the production of dust and harmful fumes. This Lenox 21889AL120080CT circular blade doesn't only ease the hard work but also provides the safety that you need.
