Read on for valuable advice about choosing core drill or diamond core bits that make your next industrial project go off without a hitch!

What Are Core Drill Bits?

Core drill bits are specially designed to cut into concrete, brick, and stone. They are usually made of high-strength carbide or steel and have teeth brazed or welded onto the bit. Depending on their size and design, core drill bits can be used with hand-held and larger electric drills. Core drill bits often feature spiral flutes that help remove debris from the hole as it is drilled, giving a cleaner finish and greater precision to the job. The cutting edges of core bits are located at their outside diameter (OD) and are straight or spiral-fluted.

What Factors Should You Consider In Selecting Core Drill Bits And Diamond Core Bits?

If you want strong, dependable cutting tools for your job site, it's time to introduce yourself to core drill bits and diamond core bits. These cutting tools are renowned for their versatility, strength, and durability. Here's how you can find the right ones for your project:

First things first, are you drilling through asphalt, concrete, or masonry? This answer will help you pick a proficient drill bit that doesn't give up midway. For example, asphalt core drill bits are specifically designed for coring a hole through medium to soft and more abrasive materials.

On the flip side, concrete core drill bits work well with wet electric or pneumatic drills. Often coring professionals discover when they are coring a hole in hard materials, like cured concrete with rebar, they find using heavy duty core bit more suitable. They have diamond segments that are ideal for drilling through hard concrete. Likewise, masonry core drill bits are designed for use with dry electric or pneumatic drills. Since they have tungsten carbide-tipped teeth, they're better for drilling through brick, block, and mortar joints.

Next, how deep do you need the drilled holes to be? It will determine the length of the core drill bit you need to purchase. Core drill bits come in various lengths, from 4 to 36 inches. If you're not sure what length you need, it's always best to err on caution and go with a longer bit. You can always shorten the bit by cutting it down to size, but you can't lengthen it if it's too short.

The faster a drilling bit rotates, the quicker it can cut through hard materials like concrete and masonry. Therefore, opt for one with a higher RPM rating&#;the higher the number, the faster it will drill into harder materials. Additionally, look for a core bit with advanced cutting edges that allow it to core a hole through hard materials more easily. 

The coring conditions you'll work in also impact the choice of which diamond core drill bits you'll want to use. When dealing with wet environments, you'll need a diamond-tipped core drill bit as they retain their sharpness better than other types of diamond core drill bits when used in these conditions. Likewise, an ordinary carbide-tipped core drill bit may suffice for dry materials&#;these are cheaper than a diamond core bit, but won't last as long when used to core a hole on wet surfaces.

If you don't want to limit the efficacy of your core bits, do check out the threads they have and compare them to the threads available on industry standard core drills. Universal threads will help you cover various drilling projects, while specialized ones will limit your coring operations. This is also important because standard threads ensure that your drill bit can fit onto any compatible machine.

Otherwise, you may end up having to purchase an adapter or custom-made equipment just to get your job done properly. Standard thread sizes vary depending on where in the world you live, so make sure to research what threads are most commonly used in your area.

The Power of Diamond a Core Drill Bit

Diamond core drill bits are specially designed to make light work of even the toughest drilling jobs. Besides covering most drilling surfaces, a quality core bit also ensure cleaner results.

Here's a closer look at how they work and why they're such a powerful tool.

How a Diamond Core Bit Works

A diamond core bit is made with a diamond-tipped cutting edge to cut through concrete, stone, ceramic, porcelain, and more. The diamond particles are bonded to the metal body using a process known as sintering, ensuring that they stay securely in place.

The Benefits of Using Diamond Core Drill Bits

Here are the main benefits of using diamond core drill bits:

Faster Drilling Speeds: Thanks to their superior cutting ability, diamond core bits can drill through the material much faster than other tools.

Less Wear And Tear On Your Drill: Because diamond core bits do most of the work, there will be less wear on your drill motor.

Cleaner Holes: With other tools, it's not uncommon to end up with a ragged or an uneven hole, especiall in concrete. However, because a diamond core bit delivers such a precise cut hole through the concrete, you'll always have a clean drilled hole, which features the exact measurements you opt for.

Work On Most Materials: As we mentioned before, diamond core bits can be used on virtually any material without fear of damage, including concrete, block, brick and more.

Conclusion

Choosing the right type of core bit for your industrial coring needs is not as complicated as it may seem. There are several tips to consider to find the best solutions suitable for your coring application features. Such as assessing the amount of holes you have to core, the type of material to be drilled, determining the speed of rotation and feed rate, dispelling any doubts by consulting with an expert, and considering the quality of the diamond cutting edge of a core bit before purchasing it.

By taking these steps into account while selecting the ideal core bit to meet your needs, you can achieve professional coring results efficiently. Call KOR-IT today and we'll provide you with great customer service and get your order delivered fast because we always have stock on hand. 

Understand the difference between diamond core bits and carbide ones. We cover what each bit can do to remove the risk of buying the wrong one.

A few factors will help you determine if you need a diamond or carbide core bit. Not the least of which is what kind of material you want to cut. To cut and grind hardened, super-dense materials, such as granite and concrete, you&#;ll want to use diamond. Diamond also works best on most non metallic materials such as fiberglass and composites.

Our guide will help you understand the difference between diamond core bits and carbide in depth so you can find the right tool for your job.

Diamond Core Bits

Superabrasive, diamond plated tools have a major edge over carbide&#;longevity and cut-rate set diamond tools apart from the rest. Initially, a diamond tool will cost more money, but this investment goes toward the extended life of the bit.

Additionally, diamond tools have a closer cut tolerance than carbide does. When used in a cutting capacity, such as a diamond hole saw, diamond tools sand and erode the work material. The smoothing effect of diamond tools allows for high tolerance cuts that are exact. A higher thermal conductivity is another hallmark of the diamond tool. They stay cooler longer and better dissipate the heat created by friction. This means they won&#;t burn the workpiece and damage it. You can even use diamond tools without coolant and they still won&#;t overheat. This is valuable in keeping the workshop clean and free of slipping hazards.

Carbide Core Bits

Carbide drill bits consist of metal&#;they&#;re either solid tungsten carbide or have tips covered in a tungsten carbide cement. Professionals can use carbide drill bits in many different industries due to their long life and durability. They are more durable than hardened steel bits, but not as much as diamond. As with any metal drill bit, there will always be wear and tear, dulling, and breakage. The good news is you can sharpen carbide bits to extend their lifespan. However, after performing several sharpening sessions, there won&#;t be any material left. To work properly, carbide tips need coolant to prevent burning and overheating. It is important to note that coolant mixed with the effluent creates a sludge that is messy and needs constant cleaning.
