How to Choose the Right Core Drill Bit and Diamond Core Bit for Industrial Standards

Introduction 

Do you need core drill bits or diamond core bits for your industrial concrete coring application? With the abundance of drills and drilling accessories, it can be overwhelming to know where to start.

This guide is designed to help any engineer sort through their choices and select the right one: by explaining how core drill bits work, delving into what characterizes a good core bit, and sharing some helpful tips that will ensure top-quality results every time.

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:

●   Drilling Materials (Asphalt, Concrete, or Masonry)

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.

●    Drilling Depth

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.

● Drilling Speed

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. 

●  Coring Conditions

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.

● Standard Threads

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 result is a core bit that is incredibly durable, with a long life and capable of delivering precise, clean cuts time after time. In fact, a diamond core bit is so tough that it can even be used to drill through materials that would damage or destroy other bits, like carbide or steel.

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. 

Longyear Bits – Selecting the Right Bit in 5 Easy Steps

Once a driller decides whether the objective is cutting faster or tripping less often, next it’s important to establish how hard the ground is to cut. Contrary to popular belief, the ground drillers cut is (probably) not the hardest ground on earth. This is where the Mohs scale comes into play. The Mohs scale is an exponential scale from 1 to 10 to quantify mineral hardness. Minerals with a higher Mohs hardness will scratch anything with a lower Mohs hardness. For example, a mineral classified as a four will scratch a three but not a five.

All the bits offered on the market today are targeting a specific range of the Mohs scale for the best performance. To determine the Mohs hardness of the rock to be drilled, a Mohs hardness scratch test kit is needed. This kit is a series of picks made of different materials that, when used properly, can determine the Mohs hardness plus or minus 0.5.

The Boart Longyear scratch test kit has four scratchers with eight replaceable tips and a sharpening stone. If the numbered tip scratches the rock, the rock is softer than the number on the tip. If a seven scratches and a six doesn’t, you know you’re in 6.5 rock. You would then select the bit created for that rock.

CHOOSING THE RIGHT CORE BIT FOR THE JOB

CHOOSING THE RIGHT CORE BIT FOR THE JOB

Concrete and masonry do a great job of supporting structures and keeping things in (or out). But what if you need to get through the wall or floor? That’s where core drills come into play.

Depending on the hardness of the material, your first decision will be whether to go with a dry or wet bit. Soft brick and block can be cut with a dry bit; concrete, stone and other hard, dense materials call for a water-cooled bit.

Dry Core Bits

Dry Star Blue Diamond Core Bits are made for coring soft brick and block using intermittent cuts that let air cool the bit.  They have good quality intermittent diamond cutters and good coring value with an 11” drilling depth. Dry Star Blue Diamond bits work with both hand-held core drills or right-angle grinders and are an excellent choice for lighter-duty, general purpose coring.

For harder brick or long-term use on multiple projects, Dry Premium Black Diamond Core Bits are made with the highest quality diamonds for the best coring performance. Premium Black Diamond bits are made with a heavier barrel wall and have wider segments to cut through harder brick and prevent segment loss. They have an 11” drilling depth and are available with 5/8” to 11” hubs.

Water-Cooled Bits

Star Blue Wet Diamond Core Bits are general purpose average- to light-duty bits for water-cooled coring of cured concrete and hard materials.  They have good quality diamond cutters and good coring value. Star Blue bits have a cut depth of 13” and are available in 17 hub diameters from 1” to 10”. Hubs up to 3” can be used with hand-held drill motors; larger diameters require mounted rigs.

The turbo segmented Heavy Duty Turbo Orange Wet Diamond Core Bit has very high quality diamond cutting segments with long coring life for use in medium aggregate concrete with moderate steel.  With serrated segments for a faster core, this water-cooled bit comes in 1½” to 16” diameters. Up to 14” diameter bits have a standard core length of 13”, while 16” diameter bits have a standard core length of 19”. Turbo Orange Wet Diamond Core Bits may be ordered with custom bonds, and extra core length is available. 

Thin wall hand-held wet diamond core bits are perfect for use with a Weka core drill.  They offer general purpose, fast coring with thinner segments that go through less material for an overall faster core. These premium-quality ½” to 6” diameter bits are also available in different lengths and bonds for cutting through tile or hard stone. Bits up to 7/8” have a 12” core length; 1” and larger have a 13” length.
