Added the Klein Tools 31872.
For general purpose cutting in metal, wood, and plastic, you'll want to choose a set of bi-metal cutters like the Diablo DHS009SPC and the DeWalt D180005. Bi-metal hole saws are made with highspeed steel to retain edge hardness and milder steel to increase its ability to take punishment. The Diablo has also been tipped with carbide so it should be able to power through thin (18 gauge) mild steel plate although they're mostly designed for cutting wood and plastic.
If your intent is to cut high gauge steel, you should be using dedicated steel hole saws like the Greenlee 660 and the Klein Tools 31872. If you do, you should always be using a cutting fluid. These act as both a lubricant and a coolant. The lubricating properties of cutting fluid prevent tip welding and reduce the wear on hole saws and drills while its cooling properties prevent excessive heat from deforming the workpiece and possibly ruining the tempering if present.
Hole saws can be very dangerous and should only be used while wearing adequate safety equipment.

It's difficult and time-consuming to saw symmetrical holes by hand, so why not use a drill with a hole saw attachment instead? These collections come with many sizes of saw head so that you can create perfect openings for a variety of projects. Most of the products featured here come with a carrying case, so professionals should feel comfortable choosing a suitable set for work from this list. In selecting entries, we looked for sets that can be used on many different materials: wood, plastic, and metal being the most common. We also made a point of including options that are appropriate for users of varying skill levels and budget requirements.
The high-quality Greenlee 660 has been added to list — and to the top spot, no less, due to its saws’ stainless steel construction and the all-around high reviews. Another extremely durable set, the DrillPro QKOAOKO124, has been added, and the Craftsman 9-37965 was removed due to fulfillment concerns.
