Hammer Drills - Tough Surfaces
What exactly is a Hammer Drill? A hammer drill, also called a percussion hammer, is used to drill into hard materials such as concrete, bricks, and other solid surfaces. Most standard drills work by using a rotary motion, which turns the bit at the bottom of the chuck; however, hammer drills have a vibratory force which acts much like a hammer striking nails. This action generates a suction stream, which sucks up the concrete or other material being drilled. The best hammer drills are designed for heavy duty drilling where a bit can be forced deep into the concrete or other material.
There are three types of hammer drills commonly used today, each designed for a specific purpose. Percipital hammer drills, also called ram drills, are used for drilling holes in concrete. Ram drills extract material at a faster rate than regular hammer drills.
Cordless hammer drills are portable and require a minimum of 9 V battery power. Because they are cordless, the operator doesn't need to bring a hammer drill with him in the workplace. Instead, he plugs it into an electrical outlet and walks away. One drawback of cordless hammer drills is that they may not work in areas where there are no power sources available.
The third type of hammer drills for construction and surface work is the light masonry drill. It is typically used for cutting holes for light masonry purposes. The cost of this drill is in the same range as the cordless one. It is available in a variety of price ranges.
Before you purchase the right hammer drills for your needs, you should first determine the best hammer drills for the job. It's best to choose a drill based on the kinds of materials that will be drilled. Different types of drilling holes for different materials require different power drills.
For concrete or masonry applications, it would be best to select a set of rotary hammers for your drilling needs. There are actually four different types of rotary hammers. These include screw-driven, double-ended, direct drive, and water-powered.
One of the most popular types of the rotary hammers for concrete or masonry drilling is the screw-driven. The advantage of using a screw hammer drill is that it provides a reliable, safe way to drill concrete or masonry material. Other rotary hammers, however, can only penetrate a very small hole. For concrete or masonry applications, the best choice would be the double-ended or direct drive hammers.
As you shop around, it would be good to have an idea about the price range that you can afford. There are basically two main categories for hammers - light duty and heavy duty. For light purposes, you can settle for the less expensive ones. However, if you need to drill heavy masonry or concrete material, then you would want to get the more powerful tool. You can find hammer drills for sale in a wide price range.
One feature that you should look for when buying a hammer drill is the chuck design. There are two types of chuck designs - regular and electric. The regular hammer drills come with a regular drum, which enables you to pound directly into the concrete or masonry material. Meanwhile, the electric hammer drills have a chuck that is much shaped like a quarter.
The final feature that you should consider is the motor of the tool. Different drills have different types of motors. Some provide a high torque, while others have a low one. You should look for the motor that provides the right torque that matches your requirements. If you are looking for the right hammer drill motor, you can consult some professional service providers.
If you are planning to get hold of the best hammer drill in order to perform various cementing and other concrete repair jobs on concrete slabs, laminated masonry, poured concrete, stucco walls, precast concrete, and pre-cast block walls, it is important that you buy the one that is suitable for the job. There are different types of these drills available in the market today, but only few of them are durable enough to work on tough surfaces. Choose the right one now!
