Tips for Using The Types of Drill Bits

There are considerations to get the most out of your beats. The first is the degree of point angle, and the second is the types of drills used for a particular job, such as starting hole, centering on a lathe, enlarging the hole, and finishing hole, and the size of drills for precision drilling measurements.

Point angle degree

Different types of bits have different sharpening angles. These different tip angles serve different purposes. The advantage of drills without an angle at the point manifests in creating blind holes with a flat bottom. Be keen when using these bits because they are sensitive to position and movement when drilling flat bottom blind holes.

The advantage of 118 degree bits is their flexibility. That’s why they are the most common drills available at most hardware stores. The advantage of drills with a 150 degree point angle is manifested in working with metal. They are designed for making holes in hard materials. However, remember that they require a firing port to function smoothly.

There are also those designed for very soft materials. They have a 90 degree point angle and are especially sharp; there is no need to drill a start hole for high quality results. Thus, you should check the angle of the bits as you buy drill bits in Australia for your workpiece. It ensures that the bits are suitable for the materials being processed.

Drill types

Avoid unnecessary waste of materials. Each type of bit has its function. You must consider the types to be used in a particular project. Some types can be applied to specific tasks, such as creating an initial hole, reaming an existing hole, or finishing a hole that has been created.

Twist drills are beneficial for a wide range of applications, come in various angles and sizes to suit a variety of workpieces. Some examples are centering, turning, and core bits. However, some requirements can only be met with twist drills, such as making holes twice the size of the hole and finishing the holes made. In these cases, core bits come in handy.

On the other hand, center bits are perfect for creating an initial hole in preparation for some more significant bits or bits to make a big hole. It can be used to form a starting hole and create a lathe center for your workpiece.

Drill size

The size of the drills is directly proportional to the size of the hole being drilled. Therefore, the drills should match the size of the hole you want to make to maintain the exact measurements needed.

Dimensions are usually given in millimeters. Consider the length of the bits if you are concerned about the depth of the hole being drilled. Find the bit diameter if you are looking for the width of the hole being made.
