Tapered countersink fi 25 mm 120 degrees DIN 347 C HSS is a tool designed for precise countersinking of holes at an angle of one hundred and twenty degrees, especially recommended for work in stainless steel, carbon steels and hard-to-machine materials. The tool is made of high-quality HSS high-speed steel in accordance with DIN 347 C, which guarantees high wear resistance and long service life even with intensive use.
The conical countersink fi 25 mm 120 degrees has three precision-ground blades, which stabilize the tool and ensure even material removal. This design minimizes the risk of vibration and improves the quality of the countersinking surface, resulting in higher productivity and fewer tool changes.
The tool's high-grade working surface improves chip removal and maintains excellent edge geometry for a long time, even in difficult cutting conditions. The tool exhibits resistance to high temperatures, reaching up to six hundred degrees Celsius.
- Stable operation of the tool thanks to three blades - provides greater countersinking accuracy and reduced vibration.
- Resistance to abrasion and overheating - the tool does not lose its cutting properties even under intensive cutting conditions.
- High durability of HSS steel - allows repeated use without loss of cutting parameters.
- Conforms to DIN 347 C - guarantees precise adaptation to industrial systems and repeatability of the process.
Metal taper countersink is a reliable choice for professionals who expect the highest precision and tool life in batch and unit machining.
