Countersink Ø16.5 mm 90° DIN 335 C HSSE is a high-quality tool for countersinking holes for countersunk screw heads and chamfering edges in metallic materials. Made from cobalt-alloyed HSSE high-speed steel, it offers excellent wear resistance and enhanced durability under difficult cutting conditions.
Thanks to a geometry based on three cutting edges, Ø16.5 mm 90° countersink provides high stability during operation, reducing vibration and enabling a smooth, clean, burr-free surface. The tool is particularly recommended for use on conventional milling machines and CNC machining centers.
Application countersink for metal includes machining unalloyed steel, cast iron, nonferrous metals, and difficult-to-machine steels. With adequate cooling, it performs exceptionally well as Ø16.5 mm 90° countersink for stainless steel, ensuring long life and precise machining.
- Three cutting edges – stabilize tool operation and improve the surface quality of the countersink.
- HSSE cobalt steel – increases abrasion and heat resistance when machining difficult-to-machine metals.
- High-quality cutting surface – ensures a clean, burr-free hole finish.
- Versatile application – performs well in many materials as a countersink for metal.
- Accuracy and durability – ideal for production cycles requiring repeatability and precision.
Ø16.5 mm 90° countersink is a reliable solution for professionals seeking a tool that combines strength, quality, and efficiency when working with metals.
