Oil Drilling Industry
Scraper Drill Bit
The drill bit body has several cutting edges fixed to it. During drilling, under the action of drilling pressure, the cutting edges penetrate the formation rock, and the cutting edges scrape up the rock in front of them as the drill bit rotates. It is suitable for unconsolidated soft formations, but with the emergence of new structures, steel scraper drill bits have been replaced in many applications.
PDC Drill Bit
The drilling principle is the same as that of the scraper drill bit, belonging to the cutting type drill bit. The cutting edges use synthetic diamond and sintered tungsten carbide, which have better strength and performance than scraper drill bits. It is suitable for relatively soft formations that are not prone to mud packing, or medium-hard, non-abrasive formations, such as argillaceous sandstone, shale, and gypsum rock. Less drilling pressure is required during drilling. Large composite PDC drill bits can effectively prevent mud packing and can be used in extremely soft formations.
Diamond Drill Bit
The cutting edges are made of natural diamonds. The larger the natural diamond particles, the greater the hardness. It breaks down rock through grinding and crushing, and is suitable for hard formations, and in recent years, it has also been used in softer formations. However, diamond drill bits are sensitive to high temperatures, so special attention must be paid to cooling the drill bit during use.
Roller Cone Drill Bit
Currently the most widely used drill bit. It achieves rock breaking through crushing, impact, and shearing actions on the rock. Because the contact area between the cutting edge and the rock is small, the drilling pressure distributed to each tooth is large, making it easy to penetrate the formation. The cutting edges can rotate freely, resulting in less resistance, making it suitable for various formations from soft to hard. When selecting a drill bit, factors such as the hardness and abrasiveness of the formation, the depth of the drilling section, easily inclined formations, and formations with alternating soft and hard layers should be considered.
Geological Exploration Industry
Diamond Drill Bits
Suitable for core drilling operations in geology, coal fields, metallurgy, building materials, mining, and other fields; exploration drilling for geotechnical engineering projects such as highways, railways, bridges, building construction, and hydropower; reinforcement drilling for weak and dangerous rock treatment, foundation reinforcement, and fractured formation grouting; large-diameter engineering drilling, hydrological well drilling, building pile foundation construction, and inverted hole construction; and drilling for tunnel ventilation, rock mass and building monitoring boreholes, and concrete sampling.
PDC (Polycrystalline Diamond Compact) Drill Bits
Excellent wear resistance and strong impact toughness; compatible with conventional drilling equipment, requiring no additional specialized equipment; multiple cutting surfaces, high drilling efficiency, long service life, and excellent bit gauge retention; can shorten the drilling cycle, effectively reduce labor intensity, and improve overall project efficiency.
Wireline Core Drill Bits
Mainly suitable for drilling operations in harder formations, specifically addressing the challenges of drilling in hard formations.
Twist Drill Bits
Designed specifically for soil formations, suitable for various soil drilling needs.
Construction Industry
Impact Drill Bits and Masonry Drill Bits
Commonly used for drilling holes in concrete, brick walls, and other building structures, such as installing picture frames, shelves, and plumbing and electrical lines. When selecting, the drill bit type and specifications should be determined based on the wall material and drilling diameter.
Glass Drill Bits and Tile Drill Bits
Used for drilling holes in glass, tiles, and other materials during renovation, such as installing mirrors and tile hangers. Strict adherence to operating instructions is necessary to avoid material cracking.
Woodworking Drill Bits
Widely used in woodworking and furniture making, such as making wooden furniture and installing doors and windows. Choosing the appropriate type of woodworking drill bit based on different processing needs can improve processing efficiency and quality.
