This is a genuine Makita TCT Makblade saw blade with a 30mm bore, 250mm circumference and 32 teeth. TCT blades are tipped with high grade tungsten carbide, which is an extremely durable material meaning you will get sharper cuts without having to worry about getting a new blade every week. These blades are also fully hardened and tensioned which allows for greater shock and impact absorption allowing your blade to live longer. They also are manufactured to have a very thin kerf to reduce both wastage and motor pressure. This blade is great for just cutting through wood to make it smaller and easier to manage as it is a rough cut.
