Whether you are drilling wet or dry, working with reinforced concrete or pre-stressed slabs, it’s important to choose the right rigs and bits for the job. The Diamond Great White Core Bore Bit and drilling rigs from Diamond Products are designed specifically for this purpose – providing maximum performance and safety when drilling through concrete. In this article, we will discuss why these rigs and bits are ideal for any concrete coring project, as well as how to select them correctly so that you get the best results every time.
What is a Concrete Coring Rig?
A core drill is a heavy-duty power tool used to drill precise holes into concrete and other hard materials, such as masonry, brick, and natural stone. Concrete coring rigs typically consist of a motor, a drill column or boom, and a chuck that holds the drill bit. Some rigs are designed to be handheld, while others are mounted on a cart or a stand for greater stability during use.
Core drills are used for a variety of applications, including creating holes for pipes, ducts, and electrical wiring, making room for structural reinforcements and preparing surfaces for demolition or renovation. Concrete coring rigs are typically heavy-duty and more specialized than standard drill tools, as they are designed to handle the high torque and pressure required to cut through hard materials.
Wet and Dry Rigs
The primary difference between the two types of rigs is the way they handle the dust and debris generated during the drilling process.
- A wet core rig uses a continuous flow of water to cool the drill bit and wash away the dust and debris generated during the drilling process. This helps to prolong the life of the drill bit and reduce the amount of dust and debris in the work area, making it a more suitable choice for larger and more complex coring tasks or for drilling into brittle materials.
- A dry core rig operates without the use of water and generates a significant amount of dust and debris during the drilling process. This type of rig is typically used for smaller, simpler coring tasks or for drilling into materials that are not particularly brittle.

The Pro Group can provide you with a quote on any of Diamond Products Core Drilling Rigs and accessories.
M-1 Complete Combination Core Drilling Rig
This is the number one selling rig in America and is great for the General Contractor.
The 2-1/2” square column is black oxidized for a modern look and features 6″ wheels to increase mobility. A dual switch/outlet control panel with an amp meter (excluding the CB700 models, which have an LED amp meter) allows you to customize settings while a vacuum pump ensures fast mounting without any anchor holes.
Four leveling screws are included on the base plus up to 14 inches of bit capacity when using one spacer block! There’s even a slide handle for easy drilling in tight areas – choose from various motor sizes too!
M-4 Multi-Purpose Core Rigs
An ideal tool for the contractor, plumber, or electrician; this reversible slide handle drill allows you to use it with either your right or left hand. Constructed of hard anodized 1-5/8” x 2” aluminum column and equipped with a top carrying handle and quick-release motor mount, this lightweight, portable unit is designed for easy transportation.
It has four adjustable slide bearings providing superior carriage rigidity along with 4 leveling screws on the base. Setup is fast & effortless at any angle up to 45o – allowing you greater flexibility when drilling.
Different Types of Concrete Core Drill Bits
Two major types of core drill bits are commonly used in concrete: Diamond Core Drill Bits and Tungsten Carbide Core Drill Bits.
- Diamond Core Bits: A diamond core bit is made from industrial-grade diamonds and is the most commonly used type of bit for concrete coring. They are very effective at cutting through hard materials like concrete and provide a fast and efficient drilling process.
- Tungsten Carbide Core Drill Bits: Tungsten carbide core drill bits are made from a mixture of tungsten carbide and steel and are typically used for drilling through softer materials or for making small, shallow holes in concrete. They are less expensive than diamond core drill bits and are often used for simpler, less demanding applications.
Benefits of Using A Diamond Core Bit
This is a specialty turbo wet core bit for use in wet drilling applications. The Diamond Great White Core Bore Bit is a diamond-tipped drilling tool used for materials such as reinforced concrete, brick, and masonry. In a GWOL configuration, the bits are for fast coring in general-purpose concrete with medium aggregate and reinforcement. In the GWSL configuration, the application is fast coring in critically hard reinforced concrete with medium aggregate.
The Great White gets its name from the “shark Tooth” segments that are built-in. This unique diamond core bit design allows the dust and debris accumulated while drilling to escape, putting less stress on the bit. This gives the tool a long life and provides savings for you in the long run. It can be used on mounted core rigs (all sizes) and hand-held motors (3” and under).
