7 11 Degree Tapered Button Drill Bits Threaded Buttons Hard Rock Drilling Bit

Button Drill Bits

This hard rock drill bit is precision-manufactured from high-quality, high-strength cemented carbide and alloy steel. The bit body is equipped with a specialized tapered or threaded connection, allowing for quick and secure installation on drill rods, ensuring stable power transmission under heavy impact conditions.
Thanks to its optimized button layout, structural design and balanced geometry, this drill bit delivers enhanced stability during rock drilling, effectively ensuring borehole straightness and improving drilling efficiency by over 10% under standard working conditions.
The product features high wear resistance, reliable impact resistance and smooth drilling performance, making it ideal for various engineering applications including mining, quarrying, rock drilling, tunnel construction, geological exploration and water well drilling.

Button Drill Bits Specification

Button Drill Bits Product Advantage

This drill bit is integrally forged with high-strength alloy steel and high-performance cemented carbide buttons, featuring uniform material properties, excellent toughness and impact resistance. It operates stably under high-frequency impact and heavy crushing conditions, and is not prone to chipping, cracking or breakage.
The bit body and carbide buttons adopt precision heat treatment and surface hardening treatment, which effectively enhance wear resistance, impact resistance and abrasion resistance, greatly reduce downhole wear and tear, and significantly prolong service life.
The tapered or threaded connecting end is precisely machined and strictly matched, ensuring high assembly accuracy, stable force transmission and firm, non-loose connection. This effectively reduces failures such as bit falling, slippage and abnormal damage, ensuring continuous and  efficient drilling operation.
