The DC HOB-O lightweight hole borer is highly portable and can be quickly centred on the workpiece - via a single centre-punch mark. Set the hole radius on the built-in scale, light the torch, start the cut and hit the switch to make smooth accurate holes in any position; virtually eliminating the need for grinding and touch up. This flame-cutting machine will cut holes from 1” to 8” (25mm to 200mm) inside diameter and from 141/2” to 48” (368mm to 1220mm) outside diameter. When mounted with magnets, each magnet foot is covered with a shield to protect it from direct flame and heat.
