Tapered countersink fi 12.4 mm 90 degrees DIN 335 C HSS is a precision tool for countersinking holes for tapered screw heads and for chamfering holes in metal parts. Made of HSS high-speed steel, it is characterized by good wear resistance and stable operation at moderate cutting parameters.
Thanks to its geometry based on three blades, the fi 12.4 mm 90-degree conical countersink ensures even cutting, quiet operation and accurate and smooth hole finish without vibration. The tool will be suitable for manual and machine processing, both in unit and batch production.
The product is dedicated to a wide range of materials - unalloyed steel, cast iron, non-ferrous metals, and - with proper cooling - as a conical countersink fi 12,4 mm 90 degrees for stainless steel. The high-quality cutting surface reduces cutting resistance and provides an aesthetically pleasing clean edge.
- Three working blades - stabilize the work of the tool and improve the quality of cutting.
- HSS steel - guarantees durability and machining efficiency at standard parameters.
- High-quality cutting surface - makes it possible to achieve clean recesses without additional finishing.
- Versatility of use - proves itself as a taper countersink for metal in various working conditions.
- Can be used in machining stainless steel - with proper cooling conditions.
The conical countersink fi 12,4 mm 90 degrees is a reliable tool for everyday work in the workshop and production, offering durability, precision and versatility.
