The Ultimate Guide to Different Drill Bit Materials

Drill bits are an asset in your toolbox because they help drilling projects turn out the right (and only) time. Whether you’re a seasoned woodworker or a metal fabrication enthusiast, your choice of drill bit materials can spell the difference between a project executed with precision and one that’s subpar. If you’re curious to know if the drill bit you have will help or hinder you, learn about it in this ultimate guide to different drill bit materials.

Understanding the Core of Your Drilling Experience

At the core of every successful drilling operation is the humble drill bit. It’s the pinch-hitter of your toolkit, working relentlessly to create holes in various materials. But not all bits are created equal, and understanding the intrinsic value of different drill bit materials can give you a significant edge.

The Anatomy of a Drill Bit

For instance, a drill bit isn’t just a sharp-pointed nail that bores into a workpiece; it’s a tool with a precise design to go through your chosen material.

Before you return the bit set, consider learning what a typical twist bit has, such as a shank that fits into the drills chuck. Then, there’s the flute—the spiral groove that removes the chips from the hole. Now you have the body—this is the main part of the drill bit that lacks flutes or margins. Like its relative, the nail, your bits point has a sharp end. The cutting lips are the edges that do the actual cutting.

Each element serves a critical function, and the combination of materials used in their design can enhance the bit’s overall performance.

The Drill Bit Material Breakdown

Drill bits come in different materials, each with properties and ideal applications.

HSS (High-Speed Steel)

HSS is the gold standard in drill bit materials because it can withstand elevated temperatures and in projects.

There are several reasons so many of our customers like HSS drill bits. For one, it’s strong—HHS bits can handle a variety of metals without dulling quickly. Also, it can hold its temper under sweltering temperatures, which is necessary in metalworking. We cannot abandon the benefit of versatility. These bits are great for most general drilling tasks and can be used with various materials.

Want to know a trick to better metalworking? Pair this bit with a lubricant to cool down your cutting edges.


Cobalt drill bits are like the hotter, more powerful sibling of HSS. These bits usually bind with HSS to create a stronger, more heat-resistant tool. Cobalt bits are rigid, second only to diamond, and can bust through the toughest metals. Like HSS, they also work well under high temperatures without losing their cutting qualities. They especially won’t lose their cool as they age.

Cobalt drill bits won’t avoid the challenge if you’re drilling hard steel or stainless steel.


Carbide drill bits are the pinnacle of strength and durability. These bits have carbon and heavy metals, such as tungsten, in their composition. With heavy metal compounds, carbide becomes the hardest of all metals, making them suitable for drilling into hardened steel and high-density materials. You won’t go wrong when using carbide because they don’t rust and are especially impactful in easily boring through concrete, brick, and stone.

So, carbide is your solution if you’re drilling into abrasives or another heavy-duty material and need stronger materials.


For the ultimate in hardness, nothing beats diamond drill bits. These bits are not solid pieces of diamond, but they have a coating that has diamond particles. That said, diamond-cut drill bits have unmatched hardness to the other materials because they best handle brittle materials. Also, unlike HSS, they produce cleaner cuts without chipping the material and have a long lifespan. Seriously, these are known as the one-and-done around here.

When drilling into the hardest, most abrasive materials, diamond is the hardest choice available.

Matching Material to the Drill Job

Selecting the right material for your drill bit isn’t just about the material you’re drilling; it’s also about the operation you’re performing.

Woodworking Wonders

Precision and cleanliness of cuts are paramount for woodworking, which is why brad-point bits with a sharp center point and two spurs are popular. They often come in HSS or high-carbon steel and are perfect for drilling clean interior holes without splintering the wood.

When you need a larger bore, a Forstner bit provides controlled and accurate drilling in wood with its round cutting edge and flat-bottom design. Again, HSS or high-carbon steel are the materials of choice here for their edge retention and ease of sharpening.

Cutting Through Metal

Metals, especially harder varieties such as stainless steel, require a bit that can maintain its sharpness and tolerate high heat. If you need a drill bit that cuts through metal, consider carbide, which shines in metal drilling environments.

Even in the most intricate metalwork, carbide and solid carbide drills ensure no detail is compromised.

Conquering Concrete and Masonry

Masonry drilling involves durable bits and bits designed with the material’s properties in mind. Drill bits designed for concrete often have a wedge-shaped carbide tip that starts drilling a large hole, allowing the rest of the bit to follow through easily.

The choice here is clear—if you’re facing off against concrete or masonry, you need carbide drill bits with unparalleled toughness and rock-breaking abilities.

The Importance of the Right Drill Bit for the Job

Your drill bit is as much a part of the process as the drill itself. Without the right bit, the drill is just a spinning stick. But with the correct materials in the bit, the drill becomes a versatile, high-powered workhorse that can puncture and penetrate a wide range of substances with unparalleled precision.

Choosing the right drill bit material isn’t about buying the most expensive or the hardest bit available. It’s about understanding the intricacies of your project, the materials you’re working with, and your expectations for the final result.
