Bosch Thin-Wall Metal Hole Saws Review
Using products like the Bosch Thin Wall Metal Hole Saw are probably the easiest way to make clean holes in sheet metal. We recently tried the Bosch HTW1 1″ Thin Metal Hole Saw on an aluminum gutter project and found it made our task of installing the down spout connection to the gutter almost effortless. Now this is not just a regular hole saw but one that is optimized to cut metal. It has a built-in spring ejector for the plug and has a 1/4″ hex shank that will fit into your impact driver. Probably the handiest feature is the shoulder that is built into the top of the bit that acts as a stop to keep the hole saw from going completely though your workpiece. The logic for this is that if you have to add a hole to an electrical panel, you can drill into the side of it without fear of the hole saw blasting though the steel wall and into the wires inside.
