Diamond Core Drill Bit Set | 25-200mm | For Concrete & HVAC Installations

Engineered for demanding professional and DIY projects, this Diamond Core Drill Bit delivers clean, precise holes from 25mm to 200mm in reinforced concrete. Its industrial-grade diamond matrix ensures fast, vibration-free drilling and extended bit life, making it the optimal tool for installing air conditioning lines, plumbing, and electrical conduits through tough masonry. Features and Benefits - Premium Diamond Segments - Industrial-grade diamond grit fused to a steel core provides maximum cutting speed and longevity in abrasive materials like concrete and rebar. - Reinforced Steel Body - High-strength, seamless steel construction prevents bending or breaking under high torque, ensuring straight, accurate holes every time. - Wet Drilling Compatible - Designed for use with water to cool the bit, which reduces dust, prevents overheating, and significantly extends the diamond segment life. - Wide Diameter Range (25-200mm) - A versatile single-bit solution for a vast array of hole sizes, eliminating the need for multiple specialized tools for most jobs. - Precision Threaded Connection - Standard universal thread ensures a secure, wobble-free fit on most core drill rigs and rotary hammer drills for stable operation. Applications - HVAC Installation - Create clean, sized holes through exterior and interior walls for running refrigerant lines, drain pipes, and ventilation ducts. - Plumbing and Electrical Work - Drill precise openings for conduit, pipes, and cables in concrete slabs, foundations, and block walls. - General Construction and Renovation - Essential for creating openings for vents, speakers, lighting, or any application requiring a large, clean core through masonry. Note For optimal performance and bit life, use with adequate water cooling and a compatible core drill rig or heavy-duty rotary hammer. Always wear appropriate personal protective equipment.
