Taper Button Bit (Hard Rock)

Feature:

● Efficient Transfer of Impact Energy: The simple tapered connection ensures minimal energy loss during the transfer of shock waves from the drill to the bit, delivering impact force directly and effectively.

● Excellent Debris Removal Capability:The bit body is typically designed with flutes that effectively remove rock dust and cuttings from the borehole during drilling, preventing re-grinding and increasing the penetration rate.

● High Abrasion Resistance and Long Service Life: Especially for button-type bits, the hardened tungsten carbide buttons are far harder than rock, significantly extending the bit's operational life and reducing the cost per meter drilled.

● Re-sharpenability (Primarily for Cross Bits): Worn cross bits can be re-sharpened multiple times for reuse, offering a low initial acquisition cost.

Applications:

Primarily used with jackhammers, stopers, and other small-scale underground drilling equipment. These machines have relatively lower impact energy, making them well-suited for this simple connection type.

● Tunnel: Taper drill bits are widely employed in tunneling projects, including the construction of highways, railways, and hydroelectric power tunnels. They play a critical role in drilling accurately positioned blast holes for rock excavation, enabling the safe and efficient progress of underground passageways through diverse rock formations.

● Construction: Taper drill bits are essential for projects requiring foundations to be set in rocky terrain or anchor points to be established. They deliver the penetration power needed for site preparation, utility installation, and other civil engineering tasks involving hard rock.

● Mining: Taper drill bits are indispensable for drilling blast holes in both underground and open-pit operations. They play a vital role in mineral extraction by effectively fragmenting hard rock formations, thereby facilitating access to valuable ores and resources.

● Quarrying：Taper drill bits are extensively used for extracting natural stone, aggregates, and other geological materials. They facilitate controlled blasting by drilling precise holes, allowing accurate and efficient removal of large stone blocks from the quarry face.
