Overview of the quick-release mandrel
Compared to other traditional hole saws, these high-performance thin-walled hole saws have a gradually changing tooth profile for fast cutting and a smooth burr-free surface. The hole saw also has a flared shoulder that acts as a safety stop, helping to prevent the hole from being drilled too deep and potentially damaging the workpiece underneath. The thin-walled body reduces heat build-up and ensures less stress on the tool. The versatile system allows for easy tool-free replacement of mandrel and springs. It adopts quenched and tempered steel structure, which has high strength and long service life. Designed for corded and cordless power tools. The universal hexagonal shank ensures a secure installation of the percussion drive and the common drill bit. The most common applications include drilling holes in wire channels, cabinets, enclosures, panels, and junction boxes.
