RUKO KEB-HSSCo-Mod.30-34,0mm Conical Countersink, 34.0 mm Cutting Diameter, HSSCo, 90°

Conical countersink with 34.0 mm cutting diameter, engineered for precise deburring, chamfering, and countersinking in steel, stainless steel, cast iron, non-ferrous metals, and plastics. The HSSCo (cobalt high-speed steel) body with ground profile ensures high wear resistance and clean cutting edges, while the 90° angle matches standard flat-head screw dimensions.

Advantages

HSSCo material provides superior hardness and heat resistance compared to standard HSS, extending tool life in demanding applications. The three-flute design and right-hand cutting direction deliver smooth, chatter-free results. The bright, uncoated surface allows easy inspection and resharpening. Module 30 shank ensures secure, precise mounting in compatible holders.
