Champion CT300-2-7/8 2-7/8" 3" Depth Carbide-Tipped Annular Cutter — Deep-Hole Cutting for Structural Steel
The CT300-2-7/8 is an exact 2-7/8" carbide-tipped annular cutter engineered for holes up to 3 inches deep in thick steel and other demanding materials. Its extended cutting depth helps reach heavy plate, structural members, and deep drilling locations where standard annular cutters cannot reach.
Ultra-hard tungsten carbide teeth and Champion's triple-edge cutting system deliver fast, clean, burr-reduced holes with controlled cutting pressure. The annular geometry removes only a thin ring of material, while the 1-1/4" shank is designed for compatible magnetic drill presses and annular cutter arbors.
