Choosing a Point Drill For Aluminum

While a typical point drill for aluminum can be used on a wide variety of materials, a specialty type may be better suited for more specific applications. A PCD drill bit is often used in the aerospace and automotive industries. Its characteristic shape and high wear resistance make it a good choice for a variety of abrasive materials. However, it is not recommended for use on ferrous metals due to the possibility of excessive wear caused by the reaction of carbon with iron.

Another type of drill point is blunt. This type has lip clearances for soft and hard materials. The blunt point drill is also good for non-ferrous materials. A self-threading screw is another option. These bits are specially designed for use on aluminum. They are very durable and are an excellent choice if you are working with a limited budget. These tools are also highly versatile and come in a wide variety of shapes and sizes.

The point angle is the angle formed at the tip of the drill bit. The point angle should be determined by the material you are drilling. Generally, harder materials require a larger point angle. Softer materials require a smaller one. The point angle will also have an effect on the shape of the hole. It also influences wear rates. This type of drill bit will produce smaller chips than a standard one. If you are using a drill bit for aluminum, you should choose one with a 135-degree point angle.

When choosing the drill bit, there are three important factors to consider: material, geometry, and coating. These three factors will determine the drilling bit that is right for your project. Choosing the right type will ensure that your project will be completed successfully without breaking a drill bit. This will also reduce the amount of time your drill bits will need to wear out. You will be more productive and efficient if you choose the right type of drill bit for your job.

Conventional split point drills feature bow-shaped chisels that wear out and create a saucer-shaped depression in the material. This pattern generates frictional heat that can cause the drill bit to turn blue and produce temperatures up to 1000oF. Because of this, a standard drill is not ideal for most applications. And a standard drill requires a large amount of thrust to start a cut, and therefore, has poor extruding properties.

A standard point drill bit is a standard bit with two cutting edges on the chisel point. It has a web in the center and tends to wobble, making it less accurate. A split point drill bit is a great choice for pilot holes and spot drilling, while a standard point drill is best for a deep hole. In addition, split point drill bits can be used in conjunction with drill presses to drill angled holes or partially overlapped holes.
