RS PRO HSS Countersink Drill Bit 25 mm Head Diameter 3 Flutes 90° Angle Model 218-624

RS PRO 218-624 is a high-speed steel (HSS) countersink drill bit featuring a 25 mm head diameter with 3 flutes at a 90° angle. It is engineered for countersinking operations on metal and wood, providing high durability and cutting efficiency due to its HSS material which withstands elevated temperatures without loss of hardness.

This countersink drill bit is designed to create a smooth chamfer around the pilot hole to enable countersunk screws to fit flush or slightly below the surface, enhancing the aesthetic and structural integrity of the assembly. It is ideal for use with manual, electric, and cordless drills with hexagonal or round shanks.

The 90° flute design ensures optimal cutting performance by reducing clogging, improving chip clearance, and offering chatter-free operation. These features collectively reduce mechanical vibration for more precise drilling and enhanced tool life.

Conforming to the DIN 335/C standard, the RS PRO 218-624 countersink drill bit is versatile for applications across power drills, robot-driven equipment, stationary drilling machines, and column drills in industrial, mechanical, and manufacturing environments.

The set contains a single high-quality countersink drill bit, making it a cost-effective tool for workshop and industrial use where precise countersinking is required. Its robust construction and design facilitate high performance and durability in demanding work conditions.

Constructed from high-speed steel for durability and heat resistance. Designed to create a chamfer allowing countersunk screws to sit flush with the work surface. Compatible with manual, electric, and cordless drill driver attachments.
