This 116mm core drill is optimized to plunge seamlessly through tough structural aggregates, offering a massive reduction on standard recommended retail pricing (RRP) due to exclusive volume batching.
Key Features & Benefits
• Next-Generation Segment Design: Crafted with an advanced, newly designed tooth profile that vastly improves tracking stability and delivers faster drilling speeds through hard masonry.

• Extended 450mm Reach: Built with an extra-long 450mm drilling depth to bore entirely through deep concrete foundation walls, structural slabs, and thick brickwork without needing barrel extensions.
• Universal Industrial Mounting: Fitted with a standard 1-1/4" UNC thread to latch securely onto your standard commercial core drilling rigs.
• Guaranteed Trade Performance: Engineered to maintain long service life and chip-free cuts in all variations of high-strength masonry.

Safety and Operational Guidelines
To protect your equipment and ensure workplace compliance, always prioritize strict site safety protocols:
1. Dry Cutting Limitations: Only utilize dry cutting methods on materials that have been explicitly verified as safe to be worked dry by your material supplier. Always review relevant material safety data sheets (MSDS) before commencing.
2. Dust Extraction: When drilling dry, appropriate HEPA-filtered vacuum dust control systems must be active to keep respirable silica dust below statutory limits.
3. Personal Protective Equipment (PPE): Full protective equipment—including high-tier respiratory protection (P2/P3 masks), safety glasses, heavy gloves, and hearing protection—is required at all times on site.
