Countersink fi 12.4 mm 120° DIN 347 A HSS is a professional tool designed for precise hole machining at an angle of one hundred twenty °, particularly for countersunk screw heads. Compliance with DIN 347 A ensures that the tool meets stringent industrial requirements for accuracy and dimensional repeatability.
Made from high-grade HSS high-speed steel, this countersink for metal offers exceptional resistance to abrasion and the high temperatures generated during intensive machining. It performs exceptionally well with difficult-to-machine materials, making it a reliable choice as Ø12.4 mm 120° countersink for stainless steel.
A key design advantage is the 3 cutting edges, which ensure stability during operation and uniform distribution of cutting forces. This produces a smooth surface in the machined hole and reduces vibration.
- 3 cutting edges – ensure stable operation, a clean finish, and high precision.
- HSS steel – enables operation under demanding thermal conditions and increases tool durability.
- Compliance with DIN 347 A – ensures geometric accuracy and repeatability in high-volume machining.
- High-quality surface – reduces chip adhesion and minimizes burr formation.
Ø12.4 mm 120° countersink is a reliable tool for professionals seeking high quality, durability, and accuracy when machining stainless steel and structural metals.
