Tapered countersink fi 16.5 mm 90 degrees DIN 335 C HSSE is a high-performance tool for countersinking holes for tapered screw heads and for chamfering edges in metal materials. Made of HSSE high-speed steel with cobalt additive, it features excellent wear resistance and increased durability under harsh cutting conditions.
Thanks to its geometry based on three working blades, the fi 16.5 mm 90-degree conical countersink provides high stability during operation, reducing vibrations and enabling a smooth, clean surface without burrs. The tool is particularly recommended for use on conventional milling machines and CNC centers.
Applications of the conical metal countersink include machining of unalloyed steel, cast iron, nonferrous metals, as well as difficult-to-machine steels. When properly cooled, it is ideal as a fi 16.5 mm 90-degree conical countersink for stainless steel, ensuring long life and precision machining.
- Three working blades - stabilize the operation of the tool and improve the quality of the countersinking surface.
- HSSE cobalt steel - improves abrasion and heat resistance when machining hard-to-cut metals.
- High-quality cutting surface - provides a clean, burr-free hole finish.
- Versatility of use - works well in many materials as a taper countersink for metal.
- Accuracy and durability - ideal for production cycles requiring repeatability and precision.
The fi 16.5 mm 90-degree conical countersink is a reliable solution for professionals looking for a tool that combines durability, quality and efficiency in metal work.
