The DIN 335 C HSSE conical countersink fi 20.5mm 90 degrees is a precision tool designed for countersinking countersunk screw heads and chamfering edges in a variety of metal materials. Thanks to its design in accordance with DIN 335 C and the use of HSSE high-speed steel with cobalt, the tool offers high resistance to wear and heat loads.

Equipped with three symmetrical blades, the fi 20.5mm 90-degree taper countersink guarantees even cutting, reduced vibration and high stability during operation. This feature translates into reproducible results and clean hole finish, which is particularly important in precision machining of technical parts.

Its use as a taper countersink for metal and as a tool for stainless steel, aluminum, bronze or brass makes it extremely versatile. The high-quality cutting surface reduces cutting resistance and provides aesthetically pleasing, smooth countersink edges.

  • Three working blades - stabilize the tool and increase the quality of the finish.
  • Precision tool geometry - enables fast and clean burr-free countersinking.
  • Surface made of HSSE - increases abrasion resistance and contributes to longer life.
  • Application for many metals - including as a conical countersink fi 20.5mm 90 degrees for stainless steel.
