The hole saw or hole saw bit is an essential tool in the bag of many handymen, construction workers, plumbers and electricians. If these people did not have a hole saw they would need to use a drill to gradually create holes in studs, floors and joists. The hole saw allows them to easily create a hole so that they can feed wire through the home as well as pipe or cable from floor to floor. A homeowner can utilize a hole saw as well to do these same things and more. Using a hole saw takes some practice but this article will show you how to properly use it.

Step 1 - Right Size for the Job

Like everything else in your tool box there is a right tool for the right job. Screwdrivers, drill bits and even hammers all have various sizes and you need to use the right size tool for what you are working with. A hole saw is no different and, in fact, the size is the most important thing about it. Before you begin to use the hole saw you need to determine the size of the hole you need to make. Use the measuring tape to determine the size of the hole. You can then choose the correct hole saw bit size.

Step 2 - Depth

You need to determine how deep you want the hole to be when you select the right hole saw bit. The standard depth that a hole saw bit goes is an inch. If you need a deeper hole, you will need to look at the bit to make sure you have the correct size.

Step 3 - Drill Choice

To get a hole saw bit to actually make a hole you'll need a drill with enough power to do so. For small holes a 12-volt will work but larger holes require more power. Just keep in mind that the exact type of drill to use will depend on the size of the hole you want to drill and the material you are drilling through.

Step 4 - Using the Hole Saw

Locate the center point of the hole you're going to drill and measure and mark the starting point. The hole saw bit will have a regular drill bit in the center which will create the pilot hole and act as a stabilizer. Line the pilot bit up with the mark you made and begin drilling the hole. Hole the drill firmly as you make the hole but do so slowly to reduce the amount of friction generated. This will not only increase the life of the drill but the life of the hole. Make sure that the hole saw drill bit you are using is sharp. A dull bit will cause the wood to be eaten and roughed up which will leave a poor finished product. If you plan to do many holes carry a sharpening tool with you to sharpen the teeth.
