Premium Tungsten Carbide Button Bit For Hard Rock Drilling With Multiple Thread Systems

Our high performance tungsten carbide button bits are professionally engineered for heavy duty rock drilling operations. Combining premium cemented carbide buttons with heat treated alloy steel bit bodies, these drill bits deliver stable penetration, exceptional wear resistance, and prolonged service life in harsh hard and abrasive rock conditions.

Equipped with full range standard thread systems including R22, R25, R32, R38, R51, T38, T45, and T51, our carbide button bits feature perfect compatibility with mainstream drill rods and shank adapters. We provide two mainstream body designs — retrac and ballistic — to adapt to diverse drilling scenarios, covering mining, quarrying, tunneling, foundation engineering and construction drilling projects.

Different from traditional chisel drill bits, our optimized face and gauge carbide button layout effectively disperses drilling impact force. This structural advantage maintains precise hole gauge stability, reduces bit wear, and ensures consistent drilling efficiency in fractured and highly abrasive rock formations.

To match varied rock hardness and drilling demands, we offer diversified carbide button profiles:

• Dome (spherical) buttons excel in hard, abrasive rock drilling with superior durability
• Parabolic and semi ballistic buttons boost drilling penetration speed for high efficiency construction
• Full ballistic buttons are ideal for soft to medium hard rock strata

The retrac body structure is specially optimized for fractured rock conditions. It effectively cleans hole walls during bit retraction, greatly improves hole straightness, and avoids drilling deviation to guarantee overall project drilling quality.

• High strength heat treated steel body + premium tungsten carbide buttons for extended service life
• Complete standard thread specifications for full drill string compatibility
• Multiple button shapes and body types for targeted rock condition adaptation
• Stable hole forming and efficient drilling for diverse engineering scenarios

Our professional technical team provides customized bit selection guidance. We can match the most suitable carbide button bit solution according to your actual rock characteristics and drilling equipment, helping you reduce operational costs and improve drilling productivity.
