• Image Unavailable Image not available forColor:
• SJ-3 Inverted Cone Geometry: The 60° taper narrows toward the tip, allowing access into countersunk holes or tight relief pockets. The diminishing diameter lets operators feather edges or enlarge pilot holes with progressive depth control
• Hard Metal Specialization: Suited for stainless steel, carbon steel, cast iron, and nickel alloys. The single-cut action bites into high-density materials where multi-cut burrs may skate
• Deep Cavity Reach: The elongated cone length (approx. 5/16") permits work inside counterbores or die relief channels deeper than a ball or tree shape can access. The tapered form also aids in deburring the intersection of crossed drilled holes
• Controlled Chamfering: The angled flank sweeps cleanly along plate edges to create uniform bevels prior to welding. Consistent flute geometry supports repeatable edge prep angles on thicker gauge metal stock
• Heat Conductive Structure: Carbide's thermal properties draw friction heat away from the cutting face into the tool body. This helps maintain edge temper when working on stainless or high-carbon steels without external coolant
