An annular cutter (also called core drill, hole cutter, or broach cutter) is a high-efficient drilling cutter with Multi-edge annular cutter. The diameter of the cutter ranges from 12mm-150mm. The product is mainly used to process the drilling hole, such as steel structure projects, rail traffic, bridging, shipbuilding, machine manufacture, and other hole processing fields. The hole drilling performance of the annular cutter is much better than the traditional twist drill, which has the characteristics of high drilling efficiency, portability, and labor-saving, thus greatly saving labor costs.

A multi-edge annular cutter is widely used in magnetic drilling machines, drilling machines, CNC drilling machines, and other machines.
