Product Description
RS PRO 218-630 is a High-Speed Steel (HSS) countersink drill bit featuring a 20 mm head diameter with 3 flutes and a 90° countersink angle. This drill bit is engineered to offer precise countersinking performance suitable for various industrial, construction, and manufacturing applications.
Made of durable HSS material, the drill bit withstands elevated temperatures without losing hardness, allowing for faster cutting and longer tool life compared to high carbon steel. Its 90° flute angle enables production of conical holes that allow countersunk screws to sit flush or slightly below the surface, preventing material damage and ensuring clean finishes.
The 3-flute design reduces clogging, improves chip clearance, and minimizes mechanical vibration during use, resulting in chatter-free operation and superior machining quality. It is compatible with manual drills, electric drills, and cordless drill drivers, making it versatile across different work environments.
Typical applications include metal and wood countersinking tasks, removal of burrs after drilling or tapping, robotic automation processes, and use in stationary or column drills and machine tools. This combination of features makes the RS PRO 218-630 drill bit an efficient and cost-effective solution for precision countersink drilling.
