Ideal 35-585 TKO Carbide Hole Cutter Kit
Ideal's TKO carbide hole cutter kit is a specialized electrical knockout tool focused on fast, clean hole cutting in sheet metal and non-metallic materials thanks to carbide-tipped cutters that hold an edge longer. Unlike punch-and-die systems that eject slugs, the TKO cutters produce precise rings and reduce the need for repeated sharpening or replacements; financially, it can lower consumable costs over time for users who frequently cut thin-gauge materials compared with softer punch sets.
