What is a CORE BARREL WITH ROUND SHANK CHISEL?

The Core Barrel with Round Shank Chisel is a specialized drilling tool fitted with round shank chisels, or conical bits, arranged along its cutting ring. These bits are optimized to break, cut, and crush through high-compression materials. As the barrel rotates, the round shank chisels penetrate and dislodge the formation, while the hollow core retains the broken fragments inside for removal.

This type of core barrel is ideal for coring fractured or hard rock formations, providing an efficient means of excavation with reduced wear on the primary drilling rig.

Key Features of CORE BARREL WITH ROUND SHANK CHISEL

• Rock-Breaking Performance: Designed for medium to hard rock, this tool offers unmatched penetration using hardened tungsten carbide round shank chisels.

• Heavy-Duty Structure: Reinforced barrel walls and flange sections are built to withstand extreme torque and axial loads.

• Efficient Material Displacement: Hollow center retains debris for smooth, clean drilling without clogging the hole.

• Replaceable Cutting Tools: Individual round shank chisels can be replaced without disassembling the entire unit, reducing downtime.

• Helical Ejector Slots: Spiral slits on the barrel body enhance spoil removal and cooling efficiency during rotation.
