Drill Bits For Metal Buyer’s Guide

Before you decide to buy a certain drill bit set for drilling into metal, there are a number of features that you should consider. With multiple options out there, you want to ensure that you purchase the set that will get your jobs done.

Here are some of the most important things to think about before making your final decision.

Drill Bit Materials

The kind of material that you choose for your drill bits can drastically change the effectiveness of the drill bit. With hard material like metal, there are few choices that will allow you the chance to drill a smooth hole through the material.

This means that you need to consider your options, and also think about what type of metals you will be drilling through.

There are some bit materials that will work great for aluminum but will not drill through hardened steel. So, here are the main materials that you should consider and the differences of each option.

HSS

This term stands for high-speed steel. This means the drill bits are much more resistant to heat than other materials when drilling and are harder than some others as well. This allows HSS bits to be used against metal without heating up and sustaining damage.

Cobalt

Drill bits made from cobalt and tough and rugged. These drill bits can be used for harder materials and can stand up to high heats as well. Cobalt is strong and drill bits that are made from this material are tough enough to drill through titanium and stainless steel.

Carbide

Drill bits that are designed out of carbide are the most heat absorbent of any other materials. Carbide drill bits can also hold a sharper cutting tip that other materials which make re-sharpening the drill bit a thing of the past.

Most drill bits are made with just a carbide tip, but you can also get some that are mostly made of carbide for a higher price.

Drill Bit Point Angle

The drill bit point angle makes a difference when you use different materials. The typical angle is 118 degrees. This means that both sides of the point are sharpened to a 59-degree angle to the middle point of the tip. This point angle is mainly used for softer materials like softer plastics and woods.

The usual point angle that is used for drilling into metal is 135 degrees because its better at handling harder materials. This type of point type will have a slightly varied shape with a less aggressive point and a large chisel.

Drill Bit Point Angle

Drill Point Lengths

The length of the drill point differs for bits that are used on different materials. With options that come with a 118-degree point, you can do a large number of softer material jobs and have a shorter length of drill point and still have a taper that filters the cut material away from the drilling area.

A flute is also made for the 135-degree drill points and helps to keep the viewing area clear of scraps of metal that have already been cut away. This angle offers a self-cleaning or sorts with the flute design actually tossing the scraps of metal away from the drill when they’re cut instead of having them gather together near the drill.

Drill Point Coatings

Each drill bit point has a coating of some kind to make the area stronger. This makes the point more durable and keeps it from breaking prematurely. There are a few different popular options, but the most common are titanium or black oxide coatings.

Titanium coatings are strong, but there are different options without that category. Titanium nitride and carbonitride and both good options, but the use of carbonitride will allow you to work with harder materials.

Drill Point Coatings

However, titanium nitride coatings offer good strength at a lower price. Also, the black oxide coating can handle friction better because they go through a heat treatment that reduces friction during drilling.

How to Drill Through Metals

Metal is a tough material to work with when you’re doing it for the first time. However, even though it may take a bit more time and effort, once you know how to get the job done, you will be able to finish many different metal drilling jobs.

The most important thing to remember when drilling into metals is to go at a slow pace. Trying to drill through hard material quickly will likely burn out your drill and cause damage to the drill bit.

Starting at a slow and steady pace and sticking to that will give you the best results. Also, the harder the metal is, the slower you want to go.

Pilot Holes

When working with drill bits, you have probably heard the term pilot hole before. This means that you will drill a hole before putting in a nail or screw. This ensures that you will not have to force the nail or screw into the material and keeps the insertion of the item easier.

For larger nails and screws, this process is important because you would likely not be able to get through the material without it.

FAQs

How do you know if a drill bit is for metal?

Most packaging for drill bits will tell you of their ability to be used for metal materials. However, if you are simply looking at one in front of you, you can tell by the flute at the drill point.

Drill bits for metal have a flute

Drill bits for metal have a flute that will help keep the metal scraps that are being cut away from staying in the way of the drill bit while it’s working.

How do you drill through steel?

To drill through steel you’ll want to get a tough material like carbide for the tips. This will ensure that you will be able to cut through the hard material.

Then, with a slow and steady pace, you will begin drilling with medium pressure. The harder the steel, the slower you will go, so don’t be afraid to take your time.

Conclusion

Trying to find drill bits for metal can be a long process for those who don’t know what to look for, but with our buyer’s guide teaching you what you need to know, you can choose the best choice for you.

Whether you’re interested in the top option, or you want to research some choices on your own, you have the knowledge to make an informed decision and get the best drill bits for metal.
