Drilling

Drilling is a necessary skill at home or doing other large-scale work. Therefore, it is important to choose the right size of drill bit for each job. Having the correct diameter hole is very important, especially if you use screws or other fasteners. Choosing the right drill bit size is the first step in doing the job right.

How to determine which size of drill bit is suitable for our work?

To determine the size of the drill bit, you need to calculate the diameter of the hole you need. Drill bits with sizes between 1mm and 20mm are the most common drill diameters. The size of the drill hole should be the same as the diameter of the central core of the screw or slightly smaller.

One of the easiest ways to determine the size of a drill bit is to check the screws you plan to use. To do this, you need to compare the diameter of your drill to the diameter of the screw to see if it fits. Having the right size allows the screw to penetrate the material properly and hold it together without play.

The drill bit should be about the same size as the center core of the screw, not the size of the screw head or spiral part. Some believe that drilling a hole smaller than the size of the screw allows the screw to fit more securely, resulting in a more stable bond. But in this case, holes that are too small may split or break the drilled object.

Drill bit types

There are different types of drills, each of which is designed for a specific job. Here are the most common drills:

• Conventional twist drills: These types of drills are the most common types of drills that are used for all types of household work and construction work. They can be used for metal, wood and plastic.
• Trench drill: This type of drill is the best drill for woodworking projects or equipment construction, because at the end of the drill there are blades that pierce the work surface according to the size of the screw head, so that the screw is level and the work is cleaner. This drill bit creates a tapered hole that fits the angle of the screw. This drill is also used for making furniture, cabinets and other woodworking projects.
• Concrete and brick masonry drill: These types of drills are used for construction and repair of houses and work better with a hammer drill.

In general, choosing the right drill size for different jobs is very important. These tips can help you choose the right size for your use:

1. Desired type of work: The type of work you want to do can be decisive. For example, to drill holes in brick or concrete walls, SDS drill bits are most commonly used and must be the correct diameter for the tool you are making the hole with or the tool you are making the hole for.
2. Type of material: Larger diameter drills are suitable for softer materials such as wood, while smaller diameter drills are more suitable for harder materials such as metals. Drills for harder materials have sharper tips and harder materials.
3. Desired hole: If you want to have a hole with a certain diameter, a drill with an equivalent diameter and the same size should be selected. For example, if you want to have a hole with a diameter of 20 mm, you should choose a drill with the same diameter.
4. Hole depth: depending on the desired depth, you should choose a drill with the appropriate length. Also, make sure the drill bit is long enough to reach the required depth.
5. Type of drill and its power: If you use a high power drill, you can use larger diameter drills for drilling. High-powered drills can drill harder materials and drill deeper.
6. Information of the drill manufacturer: Sometimes information from the manufacturer about the type of material and the use of drills is available in the package, which can help you choose the right size.
7. Trial and Error: For certain applications, you may need to experiment with different types of drills to find the best choice for your job.

In the end, it must be said that you must use the manufacturer’s information and instructions, and if needed, you can consult Hardex experts or people who have experience in this field to help you choose the right drill.

Buying the right size of drill bit

Fasteners such as screws and roll plates are very important in small and large construction projects to secure different components together. Choosing the correct drill bit size is critical to creating a more secure fastener. Depending on your needs, you can buy a drill or a whole set of different drills. For this, you can visit Hardex store and website and get help from our consultants.
