Oxi Power 127mm Diamond Concrete Core Bit Heavy Duty 470mm Long 1-1/4 UNC Thread Hole Drill 1811

• Drill Bit Diameter: 127mm
• Total Length: 470mm
• Thread Fitting: 1-1/4 UNC (Unified National Coarse)
• Primary Target Material: Concrete / Reinforced Concrete
• Drilling Type: Wet Core Drilling Preferred

Features

• Premium Olympia Gold Segment Matrix: Formulated with top-tier industrial diamond grit for rapid penetration and extended barrel lifespan.
• Laser-Welded Stability: High-strength structural welds prevent premature segment loss under high friction and thermal load.
• Extended Reach Barrel: Functional 470mm tube depth allows for clean, deep-impact single-pass drilling without requiring secondary extensions.
• Standard Industrial Fitting: Universal 1-1/4 UNC threading ensures seamless, wiggle-free compatibility with major rig setups.
• Optimized Sludge Clearance: Specifically spaced segment geometry facilitates the efficient removal of concrete slurry during continuous operations.

Applications

• Structural core drilling for plumbing installations and large-diameter drain lines.
• Creating precise structural openings for heavy HVAC ducting and ventilation paths.
• Running subterranean electrical conduits and bundled commercial utility piping.
• Extracting concrete material test cores for civil engineering and quality control diagnostics.
• Anchoring large machinery foundations and industrial structural bolts.

Usage

• Ensure the core drill rig is anchored down securely to prevent biting slippage or unexpected binding.
• Thread the 1-1/4 UNC connection firmly onto the drilling machine spindle; use anti-seize lubricant or a copper washer for easier post-job removal.
• Run a continuous, stable stream of cooling water to wash away debris and protect the diamond bond matrix from overheating.
• Apply firm, even pressure down through the drill rig carriage; let the diamond matrix cut at its own natural pace without forcing it.
