RS PRO HSS Drill Bit 10 mm Head Diameter 3 Flutes 90° Countersink Angle 218-668

RS PRO 218-668 HSS Drill Bit is a precision countersink tool designed for industrial, mechanical, and manufacturing applications requiring clean and accurate chamfering of pilot holes. The 10 mm head diameter and 3 flute configuration ensure efficient cutting performance with reduced clogging. Its 90° countersink angle facilitates optimal seating for flat head screws, ensuring flush or slightly recessed installations.

This drill bit is manufactured from high-speed steel (HSS), enabling it to withstand high temperatures without losing hardness, thereby maintaining cutting efficiency over extended use. The 3 flute design reduces material clogging and enhances chip clearance, resulting in smoother drilling and longer tool life. Ideal for use in metal and wood, it suits power drills, robotic assembly tools, stationary machines, and column drills.

RS PRO countersink drill bits conform to the DIN 335/C standard, assuring reliability and quality. They are applicable in a variety of industrial environments including machine shops, manufacturing plants, and mechanical maintenance settings. The tool's chatter-free operation minimizes mechanical vibration, reducing operator fatigue and enhancing precision.

Frequently used to deburr holes or prepare them for countersunk screws, these drill bits enhance assembly aesthetics and mechanical stability. Their cost-effective design provides a durable solution for professional and industrial users alike.
