Types of Furukawa Bits
The Furukawa drill bits are engineered to work perfectly with the Furukawa drilling machines. Several types of Furukawabits are available for different mining projects.
- Furukawa chisel bits: Used primarily on soft rock formations, chisel bits are one of the most commonly used drill bits in the mining industry. As a result of the sharp chiseling points and streamlined design, these Furukawa mining bits ensure precise and controlled drilling operations.
- Furukawa cross bits: As the name implies, the cross bit has a shape similar to a cross. This drill bit is usually used in areas with moderate to hard rock formations. The design of the cross bit enables it to deliver precise directional control and excellent borehole quality.
- Furukawa button bits: The button drill bit has a fully studded design with rounded heads resembling buttons. This drill bit offers excellent resistance to wear and superior performance. Furukawa button bits are suitable for use in tough geological conditions and high-intensity drilling applications.
- Furukawa reamer bits: The main task of the reamer drill bit is to enlarge and refine pre-existing boreholes, thereby ensuring improved hole diameter accuracy.
- Furukawa hollow bits: These specialized drill bits feature a cylindrical design with hollow centers. Besides improving chip removal, they enable fluid or air circulation during drilling operations.

HDD bits:
the diameter is commonly from 6 to 12 inches with a standard length of 6 to 12 inches.
-
Connection:
Furukawa drill bits usually have threaded connections. This type of connection connects the bit and drill pipe securely. Those connections match the power transmission and working conditions. Besides, they can withstand the twisting and pulling forces during work.
Maintenance
Due to the harsh working environment of the drill bit, its maintenance is often neglected. The following maintenance suggestions can help extend the service life of the drill bit.
- Cleaning: Remove dirt and debris from the bit and its mounting threads after each shift. This prevents thread damage and bit corrosion. Also, clean the drill rod and hole with a hydraulic quick coupling. For cleaned flushing holes and drill rods, use high-quality inhole cleaners for effective cleaning of the entire system.
- Inspection: Check the bit for signs of wear, loss, and cracking after each use. Pay particular attention to the condition of the crystal and its mounting threads. Replace the drill bit in time if any abnormality is found to avoid greater losses.
- Lubrication: Apply grease to the bit's mounting threads and lubricate the threads of the drill rod. This will facilitate disassembly and assembly during subsequent use and reduce thread wear.
- Storage: When not using the drill bit, store it in a dry and ventilated place. Use a protective cover to prevent dust and debris from falling into it. If multiple drill bits need to be stored, store them separately to avoid mutual damage.
Scenarios of Furukawa bits
The Furukawa rock drill bits are used for different purposes in the mining industry, and the type of bit used usually depends on the nature of the rock and the drilling task at hand.
- Open-pit mining: In open-pit mines, Furukawa tri-cone bits have widespread use due to their ability to efficiently drill through various rock types. They create large blast holes that help reduce and yield valuable minerals from the rock. Open-pit mines in well-known areas, such as the Luoyang area in Henan province, China, or the Jalisco region in Mexico, primarily extract copper, gold, and iron using large open-pit mines that pose a challenge in the form of significant drilling.
- Quarrying: In the quarrying industry, Furukawa integral drill steels are used for precise, controlled drilling of holes in rock to extract stone such as granite, limestone, or marble. These drill steels are part of the drilling system used to create blast holes in rock formations for stone extraction.
- Drift mining: Drift mines create horizontal tunnels or drifts to follow coal seams or ore deposits. Furukawa cross bits are commonly used in drift mines to drill exploratory holes or blast holes in rock to create tunnels for mining operations.
- Underground mining: In underground mining Furukawa drill bits are used to create vertical holes for blasting, ing, or ventilation. The drill bits create a network of tunnels and shafts that facilitate the extraction of minerals and ore deposits furukawa bit are ideal for the challenging drilling conditions encountered in some underground mines with hard rock formations.
- Geothermal drilling: Geothermal energy is a renewable energy source that is increasingly being used to generate electricity and provide direct heating.\ Furukawa bits are used in the drilling of geothermal wells to access the hot rock formations that contain geothermal energy.
How to choose Furukawa bits
-
Project requirements assessment:
It's crucial to assess the project requirements, including rock formation, hole diameter, depth, and volume. Selecting the appropriate drill bit type and size that suits the specific project requirements helps achieve effective results.
-
Drilling environment:
Consider the drilling environment, such as temperature, humidity, and atmospheric conditions. If the drilling is in a high-temperature or corrosive environment, it's necessary to select a drill bit with suitable protective coatings and materials.
-
Drill bit materials and coatings:
Choose the suitable drill bit materials and coatings based on the project needs. For example, if the drilling duration is required to be longer, consider selecting bits with high-performance coatings to enhance their lifespan.
-
Quality and performance of drill bit brands:
Understand the quality and performance of different drill bit brands and choose a reputable brand. Researching and reading reviews can provide insights into the advantages and disadvantages of various brands.
-
Cost-effectiveness:
Consider the cost-effectiveness of the drill bits by comparing their prices and performance. It doesn't always hold that higher-priced bits are better, so it's essential to evaluate the overall performance and value they offer.
Q&A
Q: Which bit can be used to dig soft and hard rock material?
A: A cross-bit or tapered bit can be used to dig soft and hard rock material. Also, if the rock is hard, one can use a rotary hammer drill or an air-powered hammer drill.
Q: What does a Furukawa rock drill bit do?
A: The Furukawa rock drill bit is used with the rock drill to make holes in hard material like rock and concrete. The bits are designed to cut through very hard material, and different shapes and sizes are available to suit different types of rock and soil conditions.
Q: How are Furukawa drill bits different from others?
A: Furukawa drill bits are different from others in that they have their brand name. Some popular brand drill bits are usually more expensive than unbranded drill bits. The latter will do the same work but will be less durable.
Q: Do diamond bits last longer than non-diamond bits?
