Rock drilling is a challenging and demanding job. To get the job done right, it’s essential to use the right type of rock drill bit. Each bit has its own unique features and uses, so it’s important to understand which one is best for the job you’re doing. In this blog post, we’ll be exploring the three main types of rock drill bits and their features so that you can make an informed decision when it comes to your next project.
The most common type of chisel bit is the “taper-tip” bit, which is designed to cut through hard surfaces such as concrete and limestone. Taper-tip bits have a tapered shape that makes it easier for the bit to penetrate into the material.
These types of bits are available in different sizes, from small diameter bits to larger diameter bits. The larger diameter bits are generally used in construction projects, while the smaller bits are better suited for drilling into hard rocks.
One of the biggest benefits of using chisel bits is that they are extremely durable and long-lasting. This makes them a great option for those looking for a reliable drill bit that can stand up to the rigors of working with tough materials.
In addition to being durable, chisel bits can also provide more precise cutting results than spade bits. The sharpened end of the bit allows it to cut through rock much faster and more accurately than spade bits. This is why they are often preferred by professionals in certain applications.
Overall, chisel bits are an excellent choice for any drilling project that involves working with hard surfaces or materials. Their durability, precision, and affordability make them an invaluable tool for contractors and DIYers alike.
The main features of button bits are their superior stability when compared to other types of rock drill bits. This is due to the threaded button design, which allows them to remain stationary while cutting into the rock surface. Additionally, they provide greater accuracy when drilling and have a longer life span due to their increased durability.
Finally, the threaded design also provides an advantage when it comes to extracting samples from the drilled hole. When using a button bit, the core sample is extracted with the drill bit itself and does not require an additional tool for extraction. This makes them a great choice for anyone looking for a reliable and easy-to-use rock drill bit.
A spade has a cylinder and a flat sharp blade on opposite sides. It is usually used to drill holes in soft ground. Spade drill bits are frequently used for drilling holes before planting a tree or installing a fence. Apart from creating holes in the ground, a spade bit can drill holes in concrete walls.
When using spade bits, it’s important to ensure that the tip is well lubricated to prevent overheating and chipping. It’s also important to start drilling slowly and gradually increase the speed as the material becomes softer. This will help prevent the bit from becoming stuck in the material and ensure that it produces a clean, accurate hole.
Rock drill bits are an essential tool for many construction and drilling projects. There are three main types of rock drill bits: spade bits, chisel bits and button bits. Spade bits are most suitable for small-scale and shallow drilling jobs, whereas chisel bits are better for masonry and stone drilling. Button bits are the most suitable for heavy-duty jobs, such as drilling through bedrock or hard steel.
No matter what type of bit you use, it is important to make sure that it is well-maintained to ensure safety and accuracy during drilling operations. With the right knowledge and maintenance, rock drill bits can make your job easier and quicker.
