Drilling

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.
