RS PRO HSS Cone Cutter Drill Bit, 6 mm to 20 mm, Bright Finish, 2 mm Max Drilling Thickness, 22 mm Shank 221-620

The RS PRO 221-620 HSS cone cutter drill bit is a high precision, industrial-grade accessory engineered for power tool use. Designed to create clean, accurate holes in a range of materials such as plastics, PC boards, alloys, and sheet metal, this bit uses high speed steel (HSS) for enhanced durability and consistent cutting performance. Its cone-shaped, tapered profile enables users to efficiently bore holes spanning from 6 mm to 20 mm diameter, making it a versatile solution for variable-size requirements.

With a maximum drilling thickness of 2 mm, this drill bit is suited for applications like panel fabrication, enclosure mounting, cable entry creation, and customized component preparation in electrical, maintenance, and light industrial workshops. The robust 22 mm shank provides compatibility with standard power drills, and the bright finish reduces surface friction - contributing to smoother drilling and less heat development during prolonged use.

One key benefit of this design is the elimination of pilot hole requirements, allowing for straightforward augering in sheet materials without additional preparatory steps. The cone cutter geometry permits seamless transition between different hole sizes with a single tool, minimizing tool changes and increasing operational efficiency. Users working with plastic, metal, or PCB substrates will appreciate the hole quality and material adaptability provided by this RS PRO solution.

Applications include metalworking shops, electrical installation projects, industrial maintenance, HVAC duct fabrication, and panel building for laboratory and manufacturing environments. The drill bit's high speed steel construction resists wear and deformation, ensuring reliable precision and repeatability over multiple uses. The single-piece format supports easy inventory management for technical teams.

With a specification profile featuring a 6 mm minimum and 20 mm maximum head size, 2 mm material thickness capacity, and a 22 mm shank diameter, this cone cutter resolves a variety of technical demands in one engineered product. As part of the RS PRO series, it is manufactured to consistent quality standards with a focus on industrial reliability.
