Key Features & Engineering

• Large Bore Capacity: The 157 mm diameter is engineered for primary utility penetrations, such as large sewage headers, major ventilation trunking, and foundation passes.

• Laser-Welded Reliability: The segments are laser-welded to the steel tube, providing extreme structural integrity and heat resistance, essential for drilling through reinforced concrete and dense aggregate.

• Universal Versatility: Designed for high-speed, clean cutting across a vast range of materials, including reinforced concrete, hard brick, limestone, and abrasive masonry, minimizing bit changes.

• 400 mm Working Depth: Allows for deep boring in a single operation, maintaining alignment through thick floor slabs or structural walls.

• Efficient Debris Removal: Segment geometry is optimized to ensure that concrete slurry or dust is effectively cleared, preventing the bit from jamming under heavy load.

Application Range:

Professional construction and civil engineering. Suitable for large-diameter drainage, sewage systems, and main ventilation arteries in reinforced concrete and hard stone.
