Drill bits are among the most common and essential accessories used in construction and DIY projects. There are thousands of different types, sizes and applications for drill bits.

Exceptional Hardness: Diamonds are renowned for being the hardest known natural material. Diamond core bits leverage this hardness to slice through tough surfaces effortlessly. They maintain their sharpness over prolonged periods, making them ideal for continuous drilling.

Drill bits are metal cutting tools used with drills to create holes in many different types of materials. The most common types of drill bits are designed with helix flutes and a cutting point, and are powered to cut holes by rotation and torque from a drill.

In conclusion, both diamond core bits and carbide drill bits have their distinct advantages and applications. Diamond core bits shine when it comes to hard, precision-critical tasks, while carbide drill bits excel in versatility and affordability. To make an informed choice, evaluate your specific needs, budget, and the materials you’ll be working with. By doing so, you can ensure that you have the right tool for the job, whether you need the precision of a diamond or the reliability of carbide.

It is important to make sure that you use the correct type of drill bit to match the material you are drilling into. When choosing which drill bit to buy or use, consider its material, its strength and cutting power.

The choice between diamond core bits and carbide drill bits ultimately depends on the specific requirements of your drilling or cutting task:

In the world of drilling and cutting tools, two materials stand out as champions: diamond and carbide. These materials have revolutionized the way we approach drilling and cutting tasks in various industries, from construction to manufacturing. Diamond core bits and carbide drill bits are two distinct options, each with its unique set of advantages and applications. In this article, we will delve into the differences between these Diamond Core Bits vs. Carbide to help you make informed choices for your specific needs.

We sell a wide variety of drill bits, including individual and drill bit sets for wood, metal and plastic, masonry, HSS, cone/multi-step and more. Take a look at our extensive range.

Affordability: Carbide drill bits are generally more cost-effective than diamond core bits. This makes them a preferred choice for applications where frequent replacement may be necessary, such as in woodworking.

Drill bits are very good value for money. General purpose drill bits are the lowest price. For example, a pack of 10 HSS Roll Forged Drill Bits starts from £1.16 (inc VAT). Specialist drill bits such as multi-cut stepped bits can be more expensive. Generally, the longer and wider the drill bit, the more expensive it will be.

Versatile Applications: Diamond core bits find use in a wide range of industries, from construction to geology. They are indispensable for tasks like coring holes in concrete walls, cutting through reinforced concrete, and even extracting core samples from geological formations.

American Steven A. Morse, from Massachusetts, invented the twist drill bit in 1861. Before his invention, drilling was a slow and laborious process because drill bits were made from a pointed, sharp, flat piece of metal which overheated too quickly. He wanted to develop a more effective way to drill a hole and gained a US patent for a twist drill in 1863.

Versatility: Carbide drill bits can handle a wide variety of materials, including drilling wood, plastic, metal, and composites. This versatility makes them indispensable in general-purpose drilling tasks.

Longevity: While not as durable as diamond core bits, carbide drill bits still offer a reasonable lifespan, provided they are used within their recommended parameters.

Drill bits are used to drill small to large holes in stone, granite, marble, concrete, brick, plaster, plastic, steel, wood, composites, ceramic tiles, glass and much more.

Suitable for Softer Materials: Carbide drill bits excel in drilling soft materials, and their sharp edges are less likely to damage delicate surfaces.

Black oxide is the most basic coating used on drill bits to provide resistance to heat, lubrication and slow down oxidation to the metal. It helps extend the life of particular drill bits, but it doesn’t provide any additional strength.

Minimal Vibration: Diamond core bits produce less vibration during operation, which enhances operator comfort and reduces fatigue.

Both cobalt and titanium drill bits are used to make holes in hard, tough materials like metal. Cobalt drill bits are the toughest you can get, and have no coating, unlike titanium drill bits.

Longevity: Due to their exceptional hardness, diamond core bits have a longer lifespan compared to carbide bits. This longevity results in reduced downtime and lower tool replacement costs.

The concept of a drill bit is thousands of years old, but the modern twist drill bit that we are most familiar with was invented around 160 years ago.

These drill bits are not as robust as cobalt drill bits and you cannot sharpen them without the risk of removing some of the coating.

In terms of length, use a drill bit which is as long as the screw or object to be inserted. For example, a 40mm screw would need a drill bit that has a flute length of at least 40mm.

Carbide drill bits, on the other hand, are the workhorses of the drilling world. They have been a staple in workshops and industries for decades, offering reliability and versatility. Carbide is a compound of carbon and tungsten, known for its impressive hardness and wear resistance. Here are the key features and benefits of carbide drill bits:

Heat Resistance: Diamonds have excellent thermal conductivity, which helps dissipate heat generated during drilling. This feature prevents overheating and extends the life of the bit.

Drill bits are made from different grades of raw steel which are delivered to manufacturing plants. The steel goes through a process of cutting and heat treatment at extremely high temperatures, to harden the steel. The bits are then cleaned, tempered, grounded, fluted and pointed. Specialist drill bits go through additional processes such as split pointing.

For more specific guidance on what size of drill bit to use, refer to pilot hole charts for the particular bits and material you’re using.

Precise and Clean Cuts: Diamond core bits produce clean, precise, and smooth holes with minimal chipping or cracking of the material. This precision is essential in applications such as drilling holes for plumbing or electrical conduit.

Diamond core bits are often regarded as the pinnacle of drilling technology due to their exceptional hardness and durability. Unlike traditional drill bits, which rely on abrasion and friction to remove material, diamond core bits use synthetic diamonds embedded in the bit’s matrix to cut through hard substances like concrete, stone, glass, and even metals. Let’s explore the key characteristics and advantages of diamond core bits:

Ease of Use: Carbide drill bits are user-friendly and require minimal maintenance compared to diamond core bits. They can be sharpened using standard sharpening equipment.
