SDS-MAX and SPLINE Thick Wall Carbide Tipped Core Bit

This type of core bit is built with a thicker steel barrel and reinforced carbide teeth, allowing it to withstand higher impact forces, heat, and abrasion generated by SDS-Max and spline-drive rotary hammers.

Unlike thin-wall core bits, the thick wall design provides increased durability and stability, making it ideal for hard aggregate, cured concrete, and demanding jobsite conditions.

The bit cuts a circular groove (kerf), leaving a solid core that must be removed periodically to continue drilling deeper.

⚙️ Key Features

• Thick wall construction
  Provides maximum strength for heavy-duty applications and longer bit life in hard materials

• Carbide-tipped cutting teeth
  Engineered for high impact resistance and extended durability in reinforced concrete

• SDS-Max & spline compatibility
  Designed for large rotary hammers with higher torque output

• Deeper cutting capacity
  Typically ~4"–4-3/8" usable depth (greater than thin wall bits)

• Modular system compatibility
  Often used with adapter shanks, pilot bits, and extensions for deeper or more precise drilling

🛠️ Typical Applications

• Large conduit and pipe penetrations

• Mechanical/HVAC openings

• Structural anchoring holes

• Utility and infrastructure work

• Drilling in reinforced or high-strength concrete
