Down the hole Concave Face Drill Bit

A Down-the-Hole (DTH) concave face drill bit is a specialized tool designed for efficient and precise rock drilling in mining, construction, and quarrying operations. It is used in DTH hammer drilling systems, where compressed air drives the hammer, transferring energy directly to the bit for deep and efficient penetration.

• Design:  The concave design helps centralize the drill bit, improving hole straightness and provides a self-centering effect, reducing deviation in deep-hole drilling.  The bit is equipped with tungsten carbide buttons for high wear resistance and durability which ensures efficient penetration in hard and abrasive rock formations.  Designed with air holes and grooves to efficiently remove cuttings from the hole which reduces dust build-up and enhances drilling speed.
• Applications:  The DTH concave face drill bit is ideal for applications requiring deep and precise hole drilling.
  • Mining & Quarrying:  Used for blast hole drilling in hard rock mining and aggregate extraction; provides efficient penetration in tough rock formations.
  • Construction & Foundation Drilling:  Used in pile foundation drilling, anchor installation, and soil stabilization; helps create stable foundations for bridges, buildings, and dams.
  • Water Well & Geothermal Drilling:  Ideal for drilling deep water wells and geothermal boreholes; ensures clean, straight holes with minimal deviation.
  • Oil & Gas Exploration:  Used for exploration and preliminary drilling in petroleum extraction; provides high-efficiency drilling in deep and compact formations.
  • Tunneling & Road Construction:  Used for drilling blast holes in tunnel excavation; helps in rock bolting and ground reinforcement for underground structures.
• Materials:  Manufactured from hardened alloy steel to withstand high impact forces and is heat-treated for enhanced toughness and longevity.
• Configurations:  Concave face shape; Dome or Ballistic carbide insert shape; 3-1/2″ to 13″ bit diameter.
