As you can see, a normal metal hole saw can do a lot more than just create holes in metal. With the right attachments and accessories, you can also effectively deal with wood and masonry as well. In terms of attachments, you may need a few different saw blades and additional accessories could include masonry drill bits. You may even need to upgrade your drill so that it can provide you with more torque. Regardless of what may need to be added, many projects can be accomplished using the same fundamental tool.
