Types of Pneumatic Drilling Bits

Pneumatic drilling bits are a key part of the air hammer drilling system. They come in various forms, each designed for a specific application or type of material. All types of pneumatic drilling bits are shown in the following list:

• Flat Bits: Flat bits are also known as chisels. These are the most common types of bits that come with air hammers. Flat bits work great for directional drilling in soft rocks and for instigating fractures in hard rocks. They may also work well for drilling in non-geological materials like concrete. Modern flat bits usually feature a built-in retrievable plug that can be utilized for backfilling or cement hold.
• Pneumatic Cross Bits: Also known as a cross-chisel bit, the pneumatic cross bit has a cross-shaped head that is usually larger than that of the flat bit. This chisel-shaped bit works great for drilling blast holes or through harder rock formations. The design of this bit allows it to clear out rock debris more effectively than a flat bit.
• Bone Bits: Bone bits are also known as domed or round bits. These bits have a rounded head resembling a dome or a shapeless knob. Bone bits work perfectly for penetrating hard rock, thereby creating an expansion hole. They can also be used for blasting in the area of ore extraction. Additionally, the bit design allows for a smoother hole finish compared to other bits.
• Pneumatic Drill Augers: Generally, an auger is a tool or device used for drilling holes in a specific spiral motion. Pneumatic drill augers usually come with flighting and a cup or barrel on top of them. They are commonly used for drilling holes in soil or loose material, especially when there is a need to remove debris from the hole.

Specifications & maintenance of pneumatic drilling bits

For the air drilling bits, the following specifications are of utmost importance.

• Compatibility: This includes the drill press or air compressor's chuck size and type.
• Pressure Rating: This is the maximum air pressure, usually measured in pounds per square inch (PSI). It commonly ranges from 90 to 150 PSI, and higher pressure ratings can lead to faster drilling speeds.
• Flow Rate: This is typically measured in cubic feet per minute (CFM). It directly affects the drilling speed and efficiency. A higher CFM value is required for larger bits and faster drilling.
• Material: Drill bits are made of high-speed steel (HSS), carbide-tipped steel, chrome alloy, and other materials that affect durability and performance.
• Tread: This refers to the standard threads used in certain applications, such as NPT (National Pipe Thread).

Pneumatic drill bits need maintenance for their high performance and durability. Air holes in the bit head should be blown out after every use to keep debris from accumulating inside. A few drops of air tool oil should be added to the compressor line to keep the drill bit lubricated. The oil will allow the drill to run smoothly and prevent premature wearing. Always follow the manufacturer's instructions regarding proper care and maintenance.

Scenarios of using pneumatic drilling bits

The ability of the pneumatic drill bit to function effectively in various industries and applications shows its versatility. The most common usage scenarios include the following:

• Mining industry:

  Pneumatic drill bits are invaluable in the mining industry for drilling blast holes and creating tunnels. Their ability to drill through very hard rock material at great speed makes them the preferred tool for mining operations. Drillers use them to create holes of precise depth and diameter for explosives or short-range ventilation and drainage.

• Oil and gas industry:

  In the oil and gas industry, horizontal directional drilling (HDD) uses large-diameter, heavy-duty air hammer drill bits to create wells. HDD is a method of creating underground tunnels without disturbing the ground surface. Drill bits used in this method are large and heavy duty so they can create the underground tunnels required to access oil and gas reservoirs.

• Construction industry:

  Pneumatic drilling bits are a valuable tool for the construction industry. The tool is widely used for creating holes in concrete structures for building, infrastructure development, and demolition. When using this drill bit, the operator can create precise holes in concrete quickly and efficiently. It's applying for installation, anchoring systems, and plumbing, electrical, or mechanical work.

• Geotechnical drilling:

  The field of geotechnical engineering relies heavily on pneumatic drill bits. They are indispensable for subsurface investigations as well as sampling and soil testing. Geotechnical engineers use drill bits to extract soil samples and determine the composition and structure of the ground.

• Quarrying:

  Pneumatic drill bits are widely used in the stone quarrying industry. The drill bits are used to extract stone blocks from the quarry or pit by creating holes at specified locations and then inserting the explosives to fracture the stone. Also, the drill bits are used to create holes for wire-saw tracks. This is a method used in cutting techniques to achieve a precise size and shape.

• Utility installation:

  Pneumatic drill bits are very useful for utility installation. The drill bits help to create boreholes for laying underground cables and pipes. Using the drill bits, precise tunnels are made without disturbing the surface where utilities like water lines, electrical cables, and fiber-optic lines will be installed.

How to choose pneumatic drilling bits

It is important to select the right pneumatic drilling bits for the intended use. Businesses need to evaluate their requirements by determining the type of material they will be using the drill bit on and considering the features of the drill bit and how compatible it will be with their machinery.

• Material compatibility: The primary step in choosing the right drilling bit is to consider the material it will be used upon. Once the primary material is discovered, the user can further investigate the sub-sections, such as rock density and concrete composition. For instance, crystalline rocks like granite require specific bits that are designed precisely for them. Likewise, softer grounds like sandstone or limestone will need different bits. Similarly, when it comes to concrete, abrasive and hard-to-cut materials like porcelain will require diamond drill bits for porcelain.
• Drill bit types: There are several drill bits available, all of which have different uses and areas of expertise, as mentioned above. Apart from knowing the material of the surface, one will also need to be aware of the circumstances surrounding the situation. For instance, how large of a hole needs to be made? If a large hole is required, coring bits are the way to go. What degree of accuracy is required? If one needs to make precise holes, twist drill bits are ideal.
• Compatibility: Once the drill type has been finalized, one must ensure that the drill bit is compatible with the drilling machine. If it is not, it will simply not work.
