The Ruko-102125 is a high-precision tapered countersink, designed according to DIN 335, offering a 90° countersinking angle and a maximum diameter of 31 mm. This tool is ideal for countersinking a wide variety of materials, including non-ferrous metals, steel, thermoplastics, and hard plastics, as well as sheet metal up to 4 mm thick. Its innovative design and high-speed steel (HSS) construction guarantee exceptional performance and a long service life.
The DIN 1412 C split point and 118° cutting angle allow for easier and more precise cutting starts, while the 20/30° taper angle ensures efficient right-hand cutting.
