The Value of the Metal Hole Saw
If you had a new computer with the very latest in technology and ingenuity but you did not understand anything about the wonderful machine sitting in front of you, would your computer be used to its full potential? Would this awesome machine accomplish the purpose for which it was built? The answer is most likely no. Then many people make the mistake of thinking that the computer is of little or no use and decide to get rid of it. The better option would be to learn the use of your computer and put it to work in a way that would make life just a little easier.
Such is the case with the metal hole saw. Right from the start, many people, when they hear of this tool, think of a power tool that needs electricity to operate. This tool is not powered by electricity but to the contrary it is an attachment for either a battery operated drill or a power drill. It is designed to cut holes in a variety of materials. The most popular use for this tool to a carpenter is to cut holes in doors to fit them for door knobs. But, its use is not limited to just wood. The metal hole saw can be used on metal, plastic, nail-embedded wood, Plexiglas and a whole lot more. The options are virtually limitless as to what you can do with a metal hole saw. Even concrete and stone are no match for the diamond metal hole saw. So whether you want to cut holes in the floor joists for piping under your house or make an access for wires in the back of a desk, you will not find a more useful tool to use on these applications other than the metal hole saw.
When using a hole saw, it is important to have a drill with the capabilities to operate it. Battery operated drills of past years just could not handle the pay load needed for the operation of the metal hole saw. Nowadays there are battery operated drills that operate with either 18 or 24 volts of electricity that are sufficient to power the metal hole saw. If you are in doubt as to whether or not your drill is powerful enough, you may want to consider using a conventional power drill. There is a lot of pressure on a drill when cutting a three inch hole. Even though the metal hole saw uses a minimal amount of energy it still needs a lot of torque to be able to cut effectively. The metal hole saw only cuts the outer perimeter of the hole and thus minimizes the amount of power needed to operate. If you do not use a drill with sufficient torque, this may result in significant wear and tear on the saw itself.
As you can see, the options are endless with this wonderful tool. You can even use it to prepare the way for a tap and die set. If you use a metal hole saw with a smaller diameter you can drill through metal and then thread the metal with a tap and die set.
