With up to 300% longer life than brazed router bits; our spiral bits are a must-have in every woodworker's shop. These micro-grain carbide cutters feature our optimal helix design and a stronger body that reduces vibration and lasts up to 300% longer than regular router bits. Unlike straight router bits, Infinity solid carbide spiral bits feature a helical spiral design that is continuously in contact with the workpiece, producing smoother cutting action and the cleanest results possible. Downcut bits don't clear chips as quickly as upcut bits but their downcut geometry pushes wood fibers down into the cut and leaves a nicer quality top surface on your workpiece. They also require a slower feed rate.
