Tapered countersink fi 30 mm 90 degrees DIN 335 C HSS is a universal cutting tool for machining metals, including stainless steel, non-ferrous metals and plastics. The tool meets the requirements of DIN 335 C and is equipped with three precision blades, which significantly improve the stability of work and allow for clean and repeatable results.
The use of the countersink for metal enables countersinking of holes for countersunk screws and machining of chamfered edges. Blades with an optimized rake angle guarantee smooth entry into the material and efficient chip removal, minimizing the risk of damage to the work surface.
High-quality work surface made of hardened HSS ensures increased wear resistance and long service life when working under moderate heat load.
- Three working blades - provides stable and quiet vibration-free operation and uniform hole finish.
- High-quality HSS steel - enables durable and efficient machining of medium-hardness metals.
- Smooth cutting surface - provides a clean finish and easy chip evacuation.
- Widely applicable - works well in both single-piece and mass production.
- Adapted for stainless steel - allows use as a fi 30 mm 90 degree conical countersink for stainless steel.
Conicalcountersink fi 30 mm 90 degrees is a reliable choice for professional users expecting high quality finish and reliable tool operation in various technological conditions.
