TCT Tungsten Carbide Tipped Annular Cutters (9 Series) Hornet Cutters, 3-5/16", 4", 281 9-1-4106 C-281

Diameter Up to 6. Drilling Depth Up to 10. Standard sizes, metric sizes, and kits available. Pilot pins included up to 4 depth. See Replacement Pilot Pins. Benefits. Cutters up to 4 depth come with corresponding pilot pin. Tungsten carbide-tipped teeth deliver superior hardness and wear resistance. Use high-speed RPM for best results and faster holemaking. Produces smooth, burr-free holes with excellent dimensional accuracy. Available in multiple cutting depths, imperial and metric, to handle heavy plate, structural steel, and hardened materials. 3 4 or 1-1 4 shank options available. Applications and Usage. TCT Annular Cutters (Tungsten Carbide-Tipped) are ideal for large-diameter holes and drilling steel with rust or paint. Drill steel, stainless steel and hard metals. Perfect for drilling through hardened or thick steel sections used in construction and industrial steelwork. Ideal for applications where HSS cutters struggle, including stainless, Inconel, and other high strength alloys. Supports technicians drilling into hardened machinery frames, equipment housings, and structural components. See Recommended Speed and Feed Chart for Tungsten Carbide-Tipped Cutters.
