• Tool Type: Diamond Core Drill Bit
• Drill Bit Diameter: 40mm
• Total Length: 470mm
• Thread Type: 1-1/4" UNC
• Cutting Method: Wet Drilling
• Target Material: Concrete, Reinforced Concrete, Hard Masonry, Brick

Features

• High-Grade Diamond Segments: Formulated with premium synthetic diamond grits for exceptionally fast cutting speeds and an extended operational lifespan.
• Deep Hole Reach: Features a generous 470mm barrel length to bore through thick concrete slabs, foundations, and retaining walls in a single pass.
• Industrial Standard Thread: Standardized 1-1/4 UNC thread interface guarantees compatibility with a wide range of professional handheld and rig-mounted core drilling machines.
• Laser-Welded Durability: Precision laser-welded diamond teeth dramatically minimize segment detachment risk under heavy thermal and mechanical stress.
• Efficient Slurry Clearance: The engineered barrel wall optimizes water flow to clear out concrete slurry fast, keeping the core bit cool and maintaining structural integrity.
  

Applications

• Mechanical & Plumbing: Drilling entry holes for clean water supply lines, wastewater drainage pipes, and HVAC conduit.
• Electrical Installations: Creating clean paths for heavy-duty electrical wiring, mains feeding, and structural cabling.
• Structural Engineering: Boring deep anchor holes for structural retrofitting, rebar insertion, and guardrail installation.
• Testing & Analysis: Extracting clean core cylinders from structural concrete foundations for laboratory compression and quality testing.

Usage

• Rig Alignment: Ensure the core drilling machine is firmly anchored or securely bolted to the surface to prevent vibrations that fracture the segments.
• Water Feed Setup: Always connect and run a continuous water cooling system before starting the drill to prevent segment overheating.
• RPM Management: Start the rotation at a moderate speed to let the diamond matrix score the concrete surface before applying steady downward pressure.
• Core Extraction: Once the target depth is reached, gently back the bit out while it is still rotating to prevent the core sample from jamming inside the barrel.
