Countersink Ø8.3 mm 90° DIN 335 C HSSE is a precision tool designed for countersinking and shaping hole surfaces at an angle of ninety degrees. Made of high-performance cobalt-alloyed high-speed steel (HSSE), it provides excellent wear resistance and thermal stability even under intensive use.
Thanks to a design based on 3 cutting edges, the tool offers exceptional operating stability, reduces vibration and ensures smooth guidance through the material. The result is a smooth countersunk surface and less frequent tool replacement, which directly affects machining productivity.
This countersink for metal is ideal for machining holes for countersunk screws, chamfering and deburring. Its capabilities will be particularly appreciated by users working with stainless steel – Ø8.3 mm 90° countersink for stainless steel offers reliability and precision even under demanding conditions.
Compliant with DIN 335 C and equipped with a straight shank, the product is ideal for use on conventional machine tools and CNC machines.
- Geometry for stable operation – three cutting edges ensure secure guidance and eliminate vibration during machining.
- High durability – cobalt-alloyed HSSE steel ensures resistance to wear and elevated temperatures.
- Versatile applications – ideal for hole machining, chamfering and surface smoothing in metals and alloys.
- Professional finish – compliance with DIN 335 C enables precise preparation of holes for screw heads.
Ø8.3 mm 90° countersink is an effective solution for production facilities and workshops that require high-quality tools for reliable machining of metal and stainless steel.
