Buying Guide – How to Pick the Right Core Drill Bits

There are many variables that go into choosing the right drill bit. While some of these variables are pretty straightforward, you still want to be sure you choose the right bits for your project.

Here then are some of the most important factors to consider when shopping for one.

Shape

The shape of core drill bits allows for cutting holes in corners, which is why they are often used in the construction industry when building concrete buildings or homes.

The corners of rooms can be drilled using this specialty bit so that wires, pipes and other important elements can be added later on without having to make any additional cuts in the wall.

Material

When choosing a drill bit, it is important to take into consideration the material you will be drilling. For instance, if you will be drilling through heavy-duty or thick materials, you need to use a strong, durable and powerful bit.

However, for drilling softer materials like wood or plastics, there are special drill bits designed specifically for those materials that have less resistance.

Product Name and Brand

The name of the product itself and the brand associated with it is a good indication of how reliable and effective the product will be when doing various tasks.

A company that makes several different types of products may be more experienced in designing tools for specific uses than one specializing in only one type of product. This is an important factor in determining the quality of the product.

Type

Core drills are available in two main types: twist drills and step drills. Twist drills have ridged edges that cut into the material with each revolution.

Step drills on the other hand, come in sets that are used sequentially to create a hole all the way through a material. While you can use them on soft materials such as wood or plastic, they often break through these types of materials if you’re not patient enough to work slowly and carefully.

The difference between these two types of core drill bits is their cutting structure. The cutting structure’s design is based on two main factors: the material you’ll be drilling through and the size of core drill bit needed to create a hole in that material.

FAQs on Core Drill Bits

Here, we have answered some commonly asked questions about the best core drill bits that we believe will help you get a better understanding.

Q: Can I use a normal drill for core drilling?

Yes, that is possible. All you have to do is go easy on it by letting the drill rest frequently. Get the hammer off then drill the pilot and clean out every few minutes.

Q: Can you use a hammer drill for core drilling?

Yes, you can but it is not advisable.

Q: Should I use water when drilling concrete?

That depends but the thing is that water will help arrest the dust that is generated from drilling. Moreover, the water can prevent your bit from overheating which is a good thing.

Our Top Pick

After assessing all the products, we have chosen the EDiamondTools Dry Core Bit as our top pick. Why? Simply because it is extremely easy to use, and is built to offer durability.

Away from that, it is also one of the most reasonably priced on our list and it doesn’t compromise on quality because of that. This is what is called value for money so you can understand why we picked it.

Final Thoughts

When it comes to picking the best core drill bits there is no one size fits all answer. There are hundreds of different types available, each with their own benefits and drawbacks depending on your particular needs.

Of course, that can leave you confused and overwhelmed but after going through this guide, that should not be a problem. Wouldn’t you agree?
