Taper bits, especially Tapered button bits are the most popular tapered drill bits with a wide selection of head diameters from 26mm to 48mm. With carbide buttons hot pressed on the bit skirts, tapered button bits have a good drilling performance and are excellent in longevity.
• Shank sizes: Hex. 19mm, Hex. 22mm, and Hex. 25mm;
• Carbide type: Chisel type, Cross type, Button type.
Taper drill bits are engineered with specific characteristics to optimize drilling operations across various rock conditions and scenarios. Their design integrates several key features for enhanced performance:
- Zinc-Coated Skirt for Enhanced Efficiency: The bit’s skirt is meticulously zinc-coated, specifically designed to augment friction between the drill bit and the drill rod. This improved grip minimizes slippage during rotation, ensuring more efficient power transfer and superior drilling performance, ultimately leading to faster penetration rates in diverse geological formations.
- Hot-Mounted Alloy Buttons for Accuracy and Durability: Premium alloy buttons are precisely hot-mounted into the drill bit body using advanced techniques. This secure embedding process guarantees exceptional accuracy in drilling, maintaining consistent hole geometry, and significantly enhances the overall durability of the bit, allowing it to withstand prolonged and arduous drilling tasks with reliability.
- Reliability from Premium Materials: The unwavering reliability of these drill bits stems from the meticulous selection of premium-grade drill bit materials combined with high-quality alloy buttons. This superior material composition ensures that the bits can endure extreme forces, high temperatures, and abrasive conditions encountered during drilling, maintaining structural integrity and consistent performance.
- Diverse Designs for Varied Drilling Scenarios: Taper drill bits are available in various types, each thoughtfully designed to cater to distinct drilling scenarios and specific rock conditions. This versatility ensures optimal bit selection for formations ranging from soft to extremely hard, maximizing drilling efficiency and effectiveness regardless of the geological challenges presented.
- Cost-Effective Performance with Extended Lifespan: These drill bits offer remarkable cost-effectiveness, providing excellent performance at competitive and reasonable prices. Notably, their innovative design and robust construction ensure a lifespan that ranges from 82% to 92% of their famously branded counterparts, delivering significant long-term value and reducing operational expenses.
Taper drill bits, when coupled with taper drill rods, are indispensable tools across a variety of demanding drilling applications, primarily in hard rock formations. Their design allows for efficient energy transfer, making them highly effective in challenging geological conditions for creating blast holes and other boreholes.
- Tunneling: Taper drill bits are extensively utilized in tunneling projects, from highway and railway tunnels to hydroelectric power tunnels. They are crucial for creating precisely placed blast holes to excavate rock, facilitating the safe and efficient advance of underground passages through various rock types.
- Construction: In general construction, particularly where foundations need to be laid in rocky terrain or for creating anchor points, taper drill bits provide the necessary penetration. They are vital for tasks like site preparation, utility installations, and other civil engineering projects that encounter hard rock.
- Mining: These drill bits are fundamental to the mining industry, both in underground and open-pit operations, for drilling blast holes. They play a critical role in the extraction of various minerals and ores by efficiently breaking up hard rock formations to access valuable resources.
- Quarrying: Taper drill bits are widely employed in quarrying for the extraction of natural stone, aggregates, and other geological materials. They are used to drill holes for controlled blasting, enabling the precise and effective removal of large blocks of stone from the quarry face.
