Buyer’s Guide

What are the Best Drill Bits for Metal Made of?

Titanium (Coating) Drill Bit

Titanium is a metal that is known for its corrosion resistance. It is also a very strong metal, which makes it ideal for drill bits. Titanium-coated drill bits are some of the best drill bits for aluminum because they can withstand high temperatures. The titanium coating also helps to prolong the life of the drill bit.

High-Speed Steel (HSS) Drill Bit

High-speed steel drill bits are also good for drilling into aluminum.

HSS is a type of steel that is very strong and can resist high temperatures.
This type of drill bit can maintain a sharp edge for a long time, making it ideal for repetitive drilling.

Cobalt (Steel Blend) Drill Bit

Cobalt drill bits are made of a steel blend that contains cobalt.

Cobalt (Steel Blend) Drill Bit

Cobalt is a metal that is known for its heat resistance. This type of drill bit can withstand high temperatures and is ideal for drilling into hard metals. Additionally, cobalt drill bits are less likely to break than other types of drill bits [1].

How to drill through aluminum?

Choose a suitable drill bit

When it comes to choosing a drill bit for aluminum, there are several things you need to consider. The most important factor is the type of drill bit. Two main types of drill bits can be used for drilling through aluminum:

  • High-speed steel (HSS) drill bits
  • Carbide-tipped drill bits

If you are going to be drilling through aluminum frequently, then it is worth investing in a good quality carbide-tipped drill bit. These drill bits are more expensive than HSS drill bits, but they will last much longer and will make light work of drilling through aluminum.

Choose the correct drilling speed

Another important factor to consider when drilling through aluminum is the speed at which you drill. If you drill too slowly, the heat will build up and cause the drill bit to seize. If you drill too quickly, then the friction will cause the drill bit to overheat and break.

The correct speed for drilling through aluminum is between 1500 and 3000 rpm.

Reduced pressure

When you are ready to start drilling, make sure that you apply a reduced amount of pressure.

Reduced pressure

This will help to prevent the drill bit from overheating and breaking. Start by drilling slowly and increase the speed as you go.

Lubrication

Another good tip for drilling through aluminum is to use a little bit of lubrication. This will help to reduce the amount of friction and will also prevent the drill bit from overheating. A light oil or lubricant can be used for this purpose. To lubricate the drill bit, simply apply a small amount to the tip before you start drilling.

Safety

As with any type of drilling, there is always a risk of injury. Make sure that you take all of the necessary safety precautions before you start drilling. Wear protective eyewear and gloves, and make sure that you are using a properly grounded power outlet [2].

Matters to Be a Concern Before Choosing Your Product

Speed

The speed at which your drill bit turns is an important factor to consider when choosing the best drill bits for aluminum. If the speed is too high, it can cause the bit to overheat and break. If the speed is too low, it will take longer to drill through the metal. You’ll also want to consider the type of metal you’re drilling. For example, aluminum is a softer metal than steel, so you won’t need to drill as fast.

Shape

The shape of the drill bit is also an important consideration. Drill bits come in a variety of shapes, including straight, spiral, and stepped. The type of metal you’re drilling will dictate the best type of drill bit to use. For example, aluminum is a soft metal, so a straight or spiral drill bit will work best. Stepped drill bits are designed for drilling through harder metals, so they’re not the best choice for aluminum.

Finally, you’ll want to consider the size of the drill bit. Drill bits come in a variety of sizes, from small to large. The size of the drill bit you need will depend on the thickness of the metal you’re drilling. Size also dictates the speed at which you drill. Smaller bits require higher speeds, while larger bits can be drilled at lower speeds. The average size drill bit for aluminum is between 0,125 cm and 0,25 cm.

Coating

The final factor to consider is the coating on the drill bit. Drill bits are coated with a variety of materials, including titanium and cobalt.

Coating

The type of coating you choose will depend on the type of metal you’re drilling. For example, titanium is a good choice for aluminum because it prevents the bit from overheating. Cobalt is a good choice for steel because it resists wear and tear.

Shank Design

The shank is the part of the drill bit that attaches to the drill. Drill bits come in a variety of shank designs, including straight and tapered. The type of shank you need will depend on the type of drill you’re using.

For example, if you’re using a cordless drill, you’ll need a straight shank.
If you’re using a drill press, you’ll need a tapered shank [3].


FAQ
