The Fundamentals of 80 lower drill bits

The ubiquitous 80 Lower Drill Bits are the type of bits that are utilized in the universal and commonplace activity of drilling holes. A good set of such drill bits ought to exhibit a diameter that would fall within the vast range of 3/8 inches to 5/32 inches, as well as 3/8 inches to 5/16 inches end mill bit that can be employed in conjunction with all standard drill motors.

These 80 Lower Drill Bits, which are of a standard size, are conventionally utilized for drilling wood and metal and could be employed in an array of applications that range from cutting edges and grooves to rust or other contaminants removal from steel or other metals, as well as in the installation of hardware and screws. Due to the versatility of the 80 Lower Drill Bits, they are deemed to be among the most adaptable drill bits in existence. Moreover, they are also extensively utilized in the drilling of holes in wood, plastic, metal, plaster, or masonry, to name a few.

Types of Drill Bits for 80 lower

There are several various kinds of drill bits, and it’s necessary to know what they are before we get into discussing the top drill bits for 80 lower. The most popular 80% lower drill bits include:

  1. High-speed steel (HSS),
  2. Cobalt, carbide,
  3. Diamond-coated, and
  4. Titanium drill bits.

Although HSS drill bits are the most widely available and inexpensive option, they are not optimal for drilling tough materials such as metal. Cobalt drill bits are more expensive, but they last longer and can drill through harder materials. Carbide drill bits are the most expensive yet last the longest and can drill through the toughest materials. Tile and glass can be drilled through with ease using diamond-coated drill bits. Titanium drill bits are superior in durability and temperature resistance because of their titanium coating.

How to Properly Use Drill Bits for 80 Lower

Safe practices must be followed when using 80 lower drill bits. Always take precautions by donning safety goggles and gloves. It’s also crucial to safely fasten the 80 lower before beginning drilling. To avoid the bit slipping or breaking, drill at a slow speed while maintaining constant pressure. Removing the bit and cleaning out the hole at regular intervals is also recommended.

Factors to Consider When Choosing Drill Bits for 80 Lower

I’ve used drill bits for years. I’ve never had a bad experience with them. But as a consumer, you have to be careful about what type of drill bit you buy. Here are my best tips for buying your next drill bit:


It’s important to choose a drill bit based on the material that your project calls for. You need to make sure that your drill bit is strong enough to withstand the stress placed on it. This is because most materials require specific types of bits to penetrate into them, and your drill bits should be able to withstand this stress.

You also need to make sure that the drill bits you use are compatible with your project. For example, if you’re making a wooden board, you’ll need a wood drill bit, but if you’re making a PVC pipe you’ll need a plastic drill bit. To make a choice, we recommend looking at the material and then choosing a bit that best suits it.

Cutting Length

When you’re using a drill for the first time, it’s important to start with a drill bit that’s large enough to be able to cut through the material. The size of the drill bit should be based on the thickness of the material you’re trying to cut. The thicker the material, the larger the drill bit should be.

There are two ways to measure the size of a drill bit – by diameter and by length.

  1. The diameter of the drill bit is usually expressed in millimeters (mm). So for example, a 2.5 mm bit will be half as thick as a 5 mm bit. However, when it comes to drilling bits, some manufacturers express the diameter in fractions of an inch, such as ¼” or ⅜”.
  2. The length of the drill bit is usually measured in inches. So for example, a 1-1/4” bit is one-quarter of an inch long.

Number of Flutes

When choosing your drill bit, it’s important to consider the number of flutes on your drill bit. For example, if you’re drilling a 1/4-inch hole, you’ll need a 3-flute bit, while a 5/16-inch hole requires a 5-flute bit. The larger the hole, the more flutes you need.

Also keep in mind that the smaller the flute, the finer the cut will be, while the bigger the flute, the coarser the cut will be. For example, a 3-flute bit will cut down your material to about 2.4 inches while a 5-flute bit will cut down your material to about 3.5 inches. You can usually find a wide range of sizes for each flute.

Flute Type

The type of flute that you want in your drill can depend on your purpose. If you are a drummer, you will want a straight-cut bit, which has a sharp edge and won’t get stuck in your drum heads.

If you are a guitar player, you will want a curved flute bit, which is better for cutting out grooves in your drumheads and other drum parts. And if you are a drummer, you will also want a bit that is angled slightly for easy removal of the bit from the hole after use. So, before you make your purchase, ask yourself what you need the bit for.

Most Common Types of Drill Bits

A drill bit is an indispensable part of any workbench, and most of the time, you’ll want to use your drill with a specific type of bit. If you are not familiar with the different types of bits and how to use them, it can be quite tricky to find the right tool for the job.

Drill bits are categorized into five different categories: Straight bits, angled bits, reverse-angled bits, spiral bits, and multi-fluted bits. We will discuss all of these in detail here so that you can choose the right one for your needs.

  1. Straight bits are designed to cut wood straight into flat pieces. They are used to make holes for screws, and also to drill holes into hardwood, plywood, or metal.
  2. Angled bits have a larger diameter at their tip, making them suitable for drilling holes into a wide range of materials. These bits are generally used for drilling into hardwood, but they may also be used for softwood and plastic.
  3. Reverse-angled bits are used for drilling into softwood, plywood, or even metal. They are generally used for drilling holes in thin materials like wood, plastic, and paper.
  4. Spiral bits are useful for drilling out old wood, and for removing shavings that may have accumulated on your workbench. It’s important to note that the flutes on these bits are usually not as deep as the other types, which makes them ideal for drilling into softer materials like wood and soft plastics.
  5. Multi-fluted bits are designed to drill a single hole in a certain material. These are commonly used for drilling through different types of metals, and they are often used for drilling holes in metal parts.

So, if you are looking to buy a drill bit, make sure you choose the right one according to the type of material that you will be drilling.

What is the best way to drill a hole?

There are many ways to drill a hole. You can use a drill with a guide or a hand-held drill. The best way to drill is to use a drill with a guide and to use a drill press.

Is there a difference between using a hand-held drill and a drill with a guide?

Using a hand-held drill will take longer than using a drill with a guide. Also, using a hand-held drill may be harder because you have to use more force to get the job done.

Final Words

The best drill bits for an 80 lower are the best drill bits for you. Find out what you need and then go find the ones that fit. Don’t try to do everything at once. Don’t try to fit a round peg into a square hole. Do what makes sense for you. If you need a new set of holes in your lower, you should spend some time looking at the options, picking one that works for you, and then getting the job done.
