The massive ultra-hard carbide tips on these blades are designed with a triple chip configuration that allows them to provide cleaner cuts over a longer life.
On a normal blade all the cutting workload is placed on the tiny corner point of the blade. As a result it dulls quickly and is no longer able to pierce the wood cleanly and initiate the cut. The result is a frustrating blade that must be sharpened regularly and only cuts really cleanly when it is first used after a sharpening.
Our unique triple chip blades initiate cuts along an entire edge, not just a point, so they maintain their sharpness longer. Also, because the wood-cutting action is more of a shaving than a piercing, cuts will be much cleaner and performance will not take a sharp drop as the blade slowly wears.
These blades have a 1" arbor bore and a 10 degree hook (tooth) angle.
