The blades are designed to cut up to 100 holes in materials such as wood or sheetrock. The metal cutting hold cutters are designed to cut up to 50 holes. This is an average, as the circumference of the hole affects the amount of material being cut
Each hole cutter comes with 2 sets of blades. One set of tungsten carbide blades are installed in the hole cutter. One set of HSS (high speed steel) blades are in the upper right hand corner of the carry case. Both types of blades are user replaceable and can be ordered separately

The shield remains stationary against the work being cut helping to keep the drill aligned while the rubber edge seal keeps the dust and shavings inside the collector slots. The shield operates like a portable drill press, making the hole being cut perfectly circular.
