The Ruko-102120 is a high-precision countersink, designed according to DIN 335 form C, with a 90° countersinking angle. Made of high-speed steel (HSS), this tool is ideal for countersinking a wide variety of materials, including steel, cast iron, light metals, and non-ferrous metals. Its innovative design and robust construction ensure exceptional performance in both industrial and DIY applications.
The DIN 1412 C split point and 118° cutting angle allow for a smooth and efficient start, while the 20/30° taper angle facilitates right-side cutting.
