The Ruko 102441 Countersink is a high-precision tool specifically designed for creating countersinks for cylinder head screws, hex screws, and nuts. With a diameter of 33 mm and a working length of 190 mm, this countersink is ideal for machining various materials, including steel, cast iron, aluminum, and plastic. The countersink is equipped with a Morse taper, ensuring a stable connection to the machine and enabling precise machining. The uncoated HSS (High-Speed Steel) cutting edge provides high tool life and efficiency, while the 180° countersink angle ensures burr-free and chatter-free sinking. This tool is particularly effective at low cutting speeds, resulting in optimal outcomes and extending the tool's lifespan.

• Morse taper and fixed guide pin for stable connection
