About Drill Bits

So many DIY jobs require making some kind of hole in materials, whether it be by building a cabinet, fixing a door, or fixing a grill. That is why it is essential to have a proper drill and drill bits to carry out those tasks.

Drills are one of the few inventions that made human lives so much easier. Before drills, people had to drill holes using a pointed tool and a lot of time. Then came hand-operated drills that had bits similar to the modern drills but used hand-powered mechanisms. But with the advent of electrical motors, hand drills vanished into oblivion. These days, to make a hole on wood or a wall, you can do that in a couple of seconds if you have a drill and the right type of drill bit. Read this article to find out more about them. Having a better understanding of them will help you make the right choices when you are shopping.

Different types of drill bits

As you might already know, there are at least two dozen variations among drill bits. Each one of them serves a unique function. So, the type of bit differs depending on the material you want to drill and also the size and shape of the hole. If you want to be able to choose the right type of bit for your needs, it is necessary to have at least a basic idea about these bits. That’s exactly that you will get from this article. This article features a list of the four most common types of drill bits out there. In this article, you will also find some amazing tips that you can follow while shopping for them online. 

Countersink bits

Countersink bits are designed for making relatively large holes on soft materials, like plastic and wood. The tip of these bits will have the pointy tip that holds the drill bit in place and punches the first hole. There will also be a small wing slightly above this tip that drills the actual hole on the material. If you use the drill in an existing hole, the drill will vibrate, and the resulting hole will not be perfect. For the best results, you should use countersink bits before drilling the first hole. If you want to mark the spot for the hole, you can use a pencil or a chalk marking.

Tile bits

Drilling a tile is trickier than drilling an equally hard concrete. This is because the surface of the tiles tends to be slippery, and also the outer coating of tiles is tougher than that inner material. This makes it hard to work on tiles using normal masonry bits. One notable feature of tile bits is the sharp tungsten point at the drilling tip. This sharp tip helps you place the drill on the tile without slipping even at low speeds. But to keep the tip cool while drilling, you will have to use some kind of lubricants or white spirit. Even though a normal masonry bit does not work on tiles, tile bits can work on masonry materials.

Flat wood bits

This bit is unique because of the way its tip is. The tip of a flat wood bit looks almost like a screwdriver, except for the sharp protruding point in the middle. Flat wood bits are useful for drilling relatively large holes on soft materials, especially timber and plywood. Because it is easy to drill soft materials, the actual working portion of the bit is the only tip. The rest of the bit is simply a shaft that holds the sharp portion. The size of the hole that you can drill will be exactly the same as the diameter of the drill bit. But keep in mind that you cannot use flat wood bits for enlarging existing holes in some wood.

Masonry bits

As you can tell from the name, this type of drill bits is useful for working on building materials like concrete, quarry tiles, and bricks. All of these materials are hard, and therefore masonry bits require super-strong tungsten tips to penetrate hardened concrete and other similar surfaces. In order to make it easier to identify the type and thickness of the tip of the drill bit, manufacturers use a variety of colour codes at the tip of these bits. By looking at it, you can tell how big the tip is and what material it uses. Another use of these bits is to use hammer action power drills. However, hammer action can ruin the bit quite fast.

Tips on how to buy Drill Bits Online

Having the right drill bit is essential if you want to be a DIYer. But in order to do that, you have to have the right type of bit as well, not just any bit. So, how would you find out the right type of bit for your particular job? Well, if you are a beginner, this can be overwhelming. However, it can be easier if you know what criteria to consider in them. Here are a few things that you can keep in mind while shopping for drill bits online.

  • Type of the bit – First of all, you have to decide what kind of drill bit you need for a particular work. However, this is easier said than done. You have to have at least a little bit of knowledge about various types of bits and their properties. For experienced DIYers, it is easy to tell bits apart from each other just by looking at the tip.
  • Size – Depending on the size of the screw or bolt that you are going to use in the hole that you are drilling. This is very important because if you use a drill bit that is larger than the bolt, you won’t be able to fit in the screw inside that hole. If you use a bit that is too small, then you can use a bigger bit to enlarge the hole.
  • Material – The material of the bit determines how strong the bit is going to be. Usually, the material will be some kind of alloys that is harder than the material that is being drilled. Some of the common materials for bits include carbon steel and high-speed steel. On top of that, there will be a coating on top of this. This coating can be of titanium, tungsten, zirconium, or cobalt.
  • Durability – The durability of a bit determines how many holes you can drill before the bit becomes blunt. So, having a better alloy combination and a better coating on the bit can increase the longevity of the bit. While bits do not usually come with a warranty, manufacturers do specify the number of times you can use a bit.

If you are a DIYer, you will need many other things other than drill bits. These include things like tools, screws, cutting tools, building materials, insulations, adhesives, plumbing materials, and many more. You can find any of these using our retail search engine.

Question & Answer

What is the use of step drill bits?

Step drill bits are ingenious in some ways. Usually, you will have to choose a specific size to drill a hole in metals. Unlike traditional bits that are of single sizes, step drills combine several bit sizes into one bit. This means that you can use the same bit for a variety of purposes. On top of that, step bits provide cleaner holes than regular twist drill bits. As you don’t have to spend time searching for the right sized bit, then you drill holes faster. Also, you don’t need to have a whole box of drill bits if you can combine many sizes into one bit.

Will a masonry drill bit work on metal?

Masonry bits are designed for working on hard masonry materials like bricks, stones, and concrete. However, can you use masonry bits for working on a metal? Well, yes, you can use them for making holes on metals. In some cases, masonry bits work better than bits with titanium bits that are specifically designed for metal sheets. It is easy to hold masonry bits on metal because of the nature of masonry bits. However, you have to be careful about the size of the bit that you choose. Typically, masonry bits drill holes that are twice the size of the bit.
