Please Note: Not recommended for interrupted cuts such as pipe.
- Hole Saw: A hole saw (or hole cutter) is built with an annular (ring) shape, which allows the blade to cut (or bore) out a hole in the workpiece. It's usually used along with an arbor bit and powered by an corded or cordless drill.
- Carbide Tips: Carbide tips are braised onto an edge for cutting materials. It can hold an edge ten to twenty times longer than a tool steel tip.
