Continue reading the article below in order to learn everything you need to know before choosing which drill bits to choose for metal in Australia.

Types of Metal Drilling Equipment

Metal drilling equipment typically consists of two parts: a motorized spindle (also known as a rotary tool) and a drill bit. The spindle holds the drill bit securely against the workpiece. [1]

There are three main types of drill bits: carbide, tungsten carbide/polymer composite, and diamond. [2] Each of them offers its own advantages but also drawbacks. Here’s a quick overview of each type.

Carbide Bits

These bits are made from hardened steel that is coated with a layer of hard carbides. They’re used when drilling through softer materials like cast iron, stainless steel, and mild steel. 

Carbide bits are usually less expensive than diamond bits. However, they require frequent sharpening and maintenance.

Tungsten Carbide / Polymer Composite Bits

Tungsten carbide and polymer composite bits are similar to carbide bits, except that they contain a small amount of tungsten carbide mixed into the steel. This allows these bits to cut harder materials like cast iron, steel, and stainless steel without dulling too quickly. These bits are generally more durable than carbide bits.

Diamond Bits

Diamond bits are made from synthetic diamonds that have been bonded together using an adhesive resin. Unlike carbide and tungsten carbide, diamond bits do not need sharpening. In fact, they don’t even wear down over time.

How to Choose the Best Drill Bit?

The best drill bit depends on what you’re trying to accomplish. A drill bit may be suitable for one task but unsuitable for another. If you’re drilling holes in sheet metal, then a carbide bit will perform better than a diamond bit. On the other hand, if you’re drilling a hole in soft clay, a diamond bit will perform better.

The first step is to identify the material you’re drilling. Steel, cast iron, aluminum, and titanium all require different drill bits. Next, decide which type of material you’re working with. Then, narrow it down further by considering the size of the hole you’re drilling. Finally, take note of how often you plan to use the drill bit.
