TKO^™ Carbide-Tipped Hole Cutter 4-Piece Kit

Cut faster, cleaner, and more efficiently with IDEAL Electrical TKO Carbide-Tipped Hole Cutters. Designed as a superior alternative to traditional manual knockouts, TKO cutters produce smooth, precise holes in sheet metal, reducing labor time and effort while lowering total job cost.

Equipped with fine-grain carbide teeth, these cutters deliver outstanding performance on mild and stainless steel, ensuring long tool life and consistent results. The exclusive SmoothStart replaceable pilot drill guides the cutter accurately to the surface, minimizing skidding and avoiding cutter damage. A built-in over-drill flange stops penetration beyond the metal surface, protecting underlying materials and reducing costly errors.

TKO Carbide-Tipped Hole Cutters are ideal for installing conduit and fittings in electrical panels, boxes, and enclosures—especially in tight or confined spaces where traditional methods fall short. Compatible with standard 3/8-inch or larger drill chucks and rated for low-RPM drills, TKO cutters are the reliable, professional-grade choice for precision hole cutting. Offering superior quality, performance and durability, IDEAL Electrical is the professional’s choice for carbide-tipped hole cutters.
