DIN 335-C 90° svasatore HSS testa 30 mm, gambo 12 mm, EL-CUT

Uneven edges, burrs, and poor surface finish often result from low-quality or incorrectly ground countersinks. This DIN 335-C 90° HSS Countersink Bit eliminates those issues, delivering precise, repeatable results in steel, cast iron, non-ferrous metals, and plastics. Its high-speed steel construction and precision ground profile ensure sharpness and durability, while the 90° cutting angle matches standard countersunk screw heads for flush seating.

Who is it for

Machinists, metalworkers, maintenance technicians, and serious DIY enthusiasts who demand professional-grade results. Ideal for deburring drilled holes, preparing surfaces for flat-head screws, or chamfering edges for safety and aesthetics, in both machine and hand use.
