Article: If you're only drilling a few holes through steel, you can use a regular high-speed steel bit. If you're drilling a lot of holes, or through hardened steel, then a cobalt steel bit or black oxide bit is a better choice.  Most drill bits are sold in a set with multiple sizes. If your drill bit is dull, it's not difficult to sharpen the drill bit yourself. Place the drill bit in your drill and tighten it so it’s held firmly in your drill. The smaller drill bit puts less pressure on the metal and allows you to drill larger holes easier later on. For example, if you want the hole to be 1⁄2 inch (1.3 cm) at the end, start by drilling a hole that’s 1⁄4 inch (0.64 cm). Drill presses are heavy duty machines that make sure your drill bit goes straight through the metal with the most accuracy. See if there is a workshop around you where you can use their drill press or purchase one for yourself.  There are 2 different models of drill press that you can purchase. Choose a bench drill press for a compact option that will fit right on your workbench. Pick a floor model drill press if you plan on frequently working with larger pieces of steel. If you plan on offering metal fabrication services to others, consider getting a drill press for the most accuracy. WD40 is for getting water out of rusted bolts. Place the lubricant on the end of the drill bit and on the sheet of steel you plan to drill. This helps protect the drill bit and the metal to make a smooth cut.  Spray the steel periodically while you’re drilling to keep it lubricated and reduce friction. Look for a 3-in-1 oil with a telescoping spout so you can lubricate the drill bit as it’s running.
Question: What is a summary of what this article is about?
Use a sharp bit. Use a drill bit half the diameter as the size you want to start. Work with a drill press for larger pieces of steel. Use 30 weight oil and water in a spray bottle or a lubricant oil on the drill bit.
Article: Australia has a number of different visas available depending on the reason for your visit.  For example, if you are planning on being in the country for less than three months, you can apply for a visitor visa. If you're planning on conducting business in Australia, but will be in the country less than three months, you may need a short validity business visa.  If you get a visitor visa, you may visit Australia as many times as you want during a 12 month period from the date your visa is granted. However, you cannot stay any longer than three months on each visit. You can't get a job while on a visitor visa, or study for more than three months, but you can conduct business activities such as negotiating contracts or attending conferences.  Generally, the visitor visas are available for people coming to Australia as tourists. While visiting, holders of visitor visas may participate in certain business activities.  Visitors to Australia from certain European countries may be eligible for the eVisitor visa, which is available free of charge and allows the holder to visit Australia for up to three months at a time over the course of a year.  If you want to stay for more than three months, you might be eligible for a long-stay visitor visa, which allows you to stay in Australia up to 12 months. You must be a passport holder from an eligible country. Eligible countries include the U.S. and Canada as well as many South American, African, Asian and European countries.  Australia has other specific visas that may be more appropriate for you if, for example, you are traveling to Australia to seek medical treatment or to visit family. The easiest way to get a visa application is to visit the Australia Electronic Travel Authority webpage.  The ETA system only can be used if you are outside Australia. In addition, you can only use the ETA system if you do not have tuberculosis and have not been convicted of any crimes for which you were sentenced for a total combined period of 12 months or more.  You can apply for a visa online if you live in the United States, Canada, or a few other countries. If you hold a passport from another country, you can get a visa application through a travel agent, airline, or Australian visa office. If you are applying online, you must have your passport, email address, and a credit card to complete the application. Once you've completed your application, you must submit it and pay the processing fee.  The online ETA system costs AUD $20, and accepts all major credit cards. The service charge is non-refundable, so you won't get your money back even if Australia refuses to grant your visa.  If you aren't eligible to use the ETA or eVisitor system, expect to pay fees of around AUD $135 for a visitor's visa application. When you submit your application, you will receive a reference code to use in any follow-ups. If you are using the online ETA system, you will receive a reference number as soon as you submit your application. It typically takes around 30 seconds for your application to be approved after you complete the submission process and enter your credit card information. The longest it will take to process your application if you're using the ETA system is 12 hours.

Article: Most colleges have some deadline by which point you must officially choose a major. This may be one year, two years, or more. It is good to be intentional about this decision, and to choose a major that you like. However, you may find that the act of declaring a focus makes it much easier to see what you want and don't want. Once you've spent a semester taking classes and trying to work toward a certain major, you'll have a much better idea of what it means to pursue that degree. Choose something that excites you. Don't just pick a major at random from the catalog. Be honest with yourself, and give it a real shot. Once you choose a major, you've effectively stated your purpose, and you've given yourself a track for moving forward in college. You have not, however, locked yourself into anything irreversible. Many people change their majors several times before they settle upon something. Some people even go back for a second degree. Try to keep perspective. Remember that you can always change course! If you aren't happy with the major that you pick, you can switch to something more fulfilling. If your college doesn't offer the major that you want, you can always transfer to another school. There is always a way out. Don't be afraid to dive into a major that interests you, even if you aren't 100 percent certain.  You may find that it's easy to switch between similar majors. For instance, many classes may overlap between the English degree path and the Comparative Literature path. You may find a lot of common ground between the Biology track and the Environmental Science track.  The general education requirements (GEs) are usually fairly similar across a "department" or "school" within a university. For instance, many of the introductory classes for the Mechanical Engineering track probably apply to other tracks within the engineering department. Biology, Chemistry, and Physics degree paths often require some mixture of the same introductory science courses. Many college degrees organize classes and students under broad themes and concepts, giving you plenty of room to define your own focus. Choose a concentration within the major. Supplement with a double major, if you can handle the workload. Pursue a minor (or two!) that gives you an outlet for your other interests. Don't be afraid to engage with a degree path and make it your own.
Question: What is a summary of what this article is about?
Declare a major. Recognize that this decision may not be final. Keep your eyes open. Refine your major.
