Champion CT5 Carbide-Tipped Hole Cutter — 3/16″ Depth, Tungsten Carbide Teeth
The CT5 carbide-tipped hole cutter series from Champion Cutting Tool is engineered for fast, burr-free holes in sheet metal and thin materials up to 3/16″ (≈ 4.8 mm). With precision-ground tungsten carbide cutting teeth, a spring-loaded pilot drill for quick slug ejection, and a safety collar stop to prevent over-penetration, the CT5 series delivers superior performance compared to bi-metal hole saws. Ideal for electricians, HVAC installers, sheet-metal trades, mechanical contractors and maintenance crews.
