Countersink fi 6,3 mm 90 degrees DIN 335 C HSS is a precision tool designed for professional machining of holes with a countersinking angle of ninety degrees. Made of HSS high-speed steel, it is characterized by exceptional wear resistance and high durability under intensive cutting conditions.
With 3 blades that stabilize the machining process, the tool provides an exceptionally smooth countersinking surface and reduced vibration. This directly translates into higher productivity and less frequent tool changes, especially when working with more difficult materials.
Applications of the conical metal countersink include countersinking pre-drilled holes for countersunk screw heads, as well as removing burrs and improving face quality. It is ideal for working on stainless steel, providing performance and precision unattainable by cheaper substitutes.
The tool's high-grade surface reduces friction and promotes chip evacuation, which increases tool life and machining quality. The product complies with DIN 335 C, with a cylindrical shank, dedicated to applications in conventional machines, drilling machines and CNC centers.
- High work stability - thanks to three precision blades, it provides even cutting without vibration.
- Increased tool life - HSS steel resistant to high temperatures extends tool life.
- Universal application - it will be suitable for both metal and stainless steel work.
- Compliance with DIN 335 C - guarantees full compatibility with industrial systems and assembly tools.
The ideal choice for professionals looking for a durable and precise conical countersink fi 6.3 mm 90 degrees for stainless steel, which will meet expectations even in demanding machining conditions.
