A diamond core drill bit, also referred to as a core drill bit or coring bit, is a type of drilling bit used for drilling large holes into concrete, masonry and stone.
Diamond core drill bits can be used with an electric hand drill or a drill press. They are relatively inexpensive and often come in sets that include a range of different sizes.
A diamond core drill bit contains a cylindrical shaft made from tungsten carbide tipped with diamonds. The shaft is surrounded by four blades. These blades are used to remove the material that the bit cuts through.
Diamond Core Drill Bits – How They Work
The diamonds on the main shaft grind away the material, while the blades make sure the hole has smooth sides.
Diamond core drill bits vary in size depending on their intended use. Most are between three and five inches long, but they can be up to eight inches long.
Widths range from seven-eighths of an inch to over an inch and a half. Diamond core drills also vary depending on their intended use.
Some have a flat tip for use in masonry, while others have a rounded tip for use in concrete or stone work.
Uses of Diamond Core Drill Bits
When it comes to DIY projects, nothing gets the job done quite like a diamond drill bit.
It’s a versatile tool that can be used in various applications around your house, farm or business. In fact, there are many situations where a diamond core drill bit is the only tool you need to get the job done right.
Here are several ways you can put one to work:
Drilling Through Concrete
Diamond cores can be used to drill through concrete in those situations where you need to run cables, pipes or electrical wiring.
Whatever needs to reach through the surface of the concrete must be attached to a string that is fed into the hole as it is drilled.
Drilling Holes for Fence Posts and Other Metal Structures
A diamond core can also be used to drill holes into metal for use with fence posts and fence braces. This makes it much easier to install these structures without using power tools that may damage or deform them.
Drilling Holes in Glass or Ceramics
When drilling holes in glass or ceramics, the diamond drill bit can cut through the material faster than any other drill bit.
It is also an excellent choice when you need a hole of precise size. In some cases, these drills are the only option for getting the job done.
Pipe Drilling
The diamond core bits for pipe drilling are used to drill holes through materials like concrete, stone, brick, and other masonry products.
The bits can be used to create holes for plumbing and electrical systems in new construction or in remodeling jobs. They can also be used to drill holes in existing walls to install outlets or light fixtures.
Cutting Hardened Concrete
Diamond core drills can also be used to cut through hardened concrete and stone using a special diamond blade attached to the tip of the drill bit.
This combination of the two tools makes it possible for workers to quickly demolish large areas of concrete without creating a large amount of dust and debris.
Creating Holes
Diamond core bits are commonly used to enlarge holes in existing structures or to create holes in new construction projects.
They’re typically used in conjunction with other power tools such as cordless drills or rotary hammers. Diamond core bits have a long service life, making them ideal for professionals who work daily with concrete and masonry.
Bottom Line
Diamond core drill bits are small tools that are used to drill holes in different materials. There is a wide variety of diamond core bits available and they come in a variety of sizes, shapes and materials. A common use of these tools is to drill holes into glass or porcelain.
The diamond coating on the core drill bit allows it to be used on hard surfaces while it drills through the material. The material from which the bit is made also comes into play when deciding which one to use for drilling certain materials.
Make sure you wear eye protection when using your new diamond core drill bit. Concrete and other materials can be really hard on your eyes, so always make sure to wear safety goggles and glasses when using them to ensure that nothing goes into your eyes!
