Champion CT-EXT-1/2 5" Extension for 1/2" Shank CT5/CT7 Cutters — Extra Reach for Carbide-Tipped Hole Cutters
The CT-EXT-1/2 is a precision-machined steel extension designed for Champion CT5 and CT7 carbide-tipped hole cutters with a 1/2" shank. The 5-inch extension adds approximately 4 inches of effective reach, helping operators drill through deep-set or obstructed metal locations while maintaining cutter alignment.
Use this accessory when a standard cutter setup cannot reach the work area. The rigid steel construction supports stable power transfer and controlled drilling in structural steel, panels, enclosures, mechanical rooms, and industrial maintenance applications.
