The Jetect TCT (Tungsten Carbide Tipped) Hole Saw is a heavy-duty cutting tool engineered for industrial-grade drilling. It is specifically designed to cut through tough materials that standard bi-metal saws struggle with, such as stainless steel, thick metal plates, and high-alloy steels.
FEATURES:
TCT Cutting Edge: Features high-grade Tungsten Carbide tips that offer exceptional hardness (64HRC–65HRC) and wear resistance, significantly outlasting HSS and bi-metal alternatives.
Three-Blade Geometry: Many TCT models utilize a specialized three-blade design (outer, middle, and inner blades) to reduce cutting resistance and prevent burrs, ensuring a smoother drilling experience.
Precision Centering: Equipped with a stepped pilot drill bit and a split-point design to prevent "bit walking" and ensure accurate hole placement.
Ejector Spring: Includes a high-tension spring on the pilot bit to automatically eject the cut slug (waste material) post-drilling, increasing work efficiency.
Safety Features: Often built with a safety stop collar (shoulder) to prevent over-drilling or accidental "plunge-thru," which is critical when working on electrical boxes or thin panels.
