TCT Stack Cutters (9 Series) Hornet Cutters, 3/4", 4" 9-1-424 C STACK

Diameter Up to 2. Drilling Depth Up to 4. Pilot pins included up to 4 depth. See Replacement Pilot Pins. Benefits. Tungsten Carbide-Tips deliver exceptional hardness and wear resistance. High-speed cutting of multiple layers, cutter geometry allows higher feed rates and faster holemaking. Every annular cutter comes with a corresponding pilot pin. Produces smooth, burr-free holes with excellent dimensional accuracy. Carbide tips deliver exceptional hardness and wear resistance. Applications and Usage. TCT Stack Cutters are designed specifically to cut cleanly through stacked materials, including layered steel plate, structural assemblies, and welded sections. Suitable for stacked stainless steel, hardened alloys, and abrasive materials where HSS cutters struggle. Ideal for drilling through stacked beams, plates, and structural components used in construction and industrial steelwork. Perfect for shops working with layered assemblies, welded structures, brackets, and frames. Excellent for onsite drilling where stacked materials are common, such as equipment mounting, steel erection, and infrastructure projects.
