- Product Description:Dominate Large-Scale Drilling: The Professional 5-Inch Core Bit for Industrial-Grade ApplicationsWhen your project calls for massive, clean-cut holes for major utility lines, structural penetrations, or commercial installations, standard tools fall short. The 5-Inch Diamond Core Drill Bit is engineered for contractors, industrial tradespeople, and serious professionals who demand uncompromising performance on the most demanding job sites. Featuring a rugged, durable flat segment design, the industry-standard 1-1/4"-7 heavy-duty thread, and a substantial 15-3/4" drilling depth, this core bit delivers powerful, stable, and exceptionally reliable performance in cured concrete with rebar, hard masonry, brick, block, and natural stone. Designed for both wet and dry operation, it’s the definitive tool for creating large-diameter, precision holes in plumbing, HVAC, civil, and heavy construction projects.Professional Applications & Ideal Users:Plumbing & Mechanical Contractors: Drilling holes for 5" PVC/ABS main sewer and waste lines, large-diameter storm drains, and commercial water mains. The essential large-diameter plumbing core bit for municipal and commercial tie-ins.HVAC & Mechanical Engineers: Creating openings for 5" commercial ductwork, large exhaust flues, fresh air intakes, and significant mechanical room penetrations.Electrical & Data Contractors: Running large bundles of conduit for service upgrades, data center feedthroughs, and main electrical room penetrations in commercial buildings.Civil, Construction, & Concrete Contractors: Setting large anchor bolts for structural steel, creating openings for utilities, windows, or access points in thick concrete walls, and post-tension cable access holes.Utility & Infrastructure Contractors: Installing large bollards, signage foundations, or creating penetrations for underground utilities in concrete vaults and barriers.Industrial Maintenance & Plant Operations: Creating large access holes, vents, or passages in concrete floors and walls of industrial facilities.Technical Specifications:Core Bit Diameter: 5 Inches (127 mm)Total Length: 18 InchesEffective Drilling Depth: 15-3/4 Inches (400 mm)Thread Size: 1-1/4"-7 (Heavy-Duty Industrial Thread)Segment Type: Flat Segment Design (Optimized for Durability)Application: Wet Drilling (Required for hard materials) & Dry Drilling (for select softer materials)Material: Premium Diamond Segments on High-Strength Steel CoreColor: Red (High-Visibility Protective Coating)Weight: 9.5 lbsWhat’s in the Box:1 x 5" Diamond Core Drill Bit (Fully Assembled and Ready for Professional Use)PROFESSIONAL OPERATING & SAFETY PROTOCOLS FOR HEAVY-DUTY DRILLING:MANDATORY OPERATING PROTOCOL: For cured concrete, reinforced concrete (with rebar), granite, and all hard stone, wet drilling with a consistent, high-volume water supply is absolutely non-negotiable. Dry drilling these materials with a 5-inch bit will cause catastrophic overheating, immediate glazing of the diamond segments, and certain failure, posing safety risks.Critical Starting Technique: Due to the large diameter, starting technique is crucial. Begin drilling at a 10-15 degree angle to create a substantial starting groove. Once a firm groove is established (at least 1/2" deep), carefully ease the drill to a perfectly vertical position. This prevents dangerous "skating" and ensures a clean, controlled hole start.Industrial Tool Requirement: This 5-inch bit requires a high-torque, industrial-grade rotary core drill (preferably stand-mounted for stability) with a 1-1/4"-7 threaded arbor. The drill must be specifically rated for 5-inch diameter core drilling. UNDER NO CIRCUMSTANCES use on underpowered tools, standard rotary hammers, hammer drills, or in hammer-only mode.Proper Drilling Technique: Apply firm, steady, and even pressure. Allow the diamond abrasives to grind the material—forcing it will cause binding, overheating, and damage. Use a stand or guide whenever possible for stability and safety.Essential Debris and Cooling Management: In deep holes, frequently retract the bit partially (every 1-2 inches of depth) to allow slurry to clear and the bit to cool. For wet drilling, ensure water flows directly to the cutting face. Use vacuum dust extraction for dry drilling on approved softer materials.

Extra-Large 5-Inch Diamond Core Bit with 400mm Drilling Depth：Engineered for the most demanding large-bore applications, this professional 5-inch diamond core bit provides a substantial drilling depth of 15-3/4 inches (400mm). Featuring a standard 1-1/4"-7 thread, it ensures seamless compatibility with most core drill machines, delivering stable and powerful performance for heavy-duty tasks in reinforced concrete and hard masonry. Optimized for Wet Drilling in Reinforced Concrete & Hard Masonry：Confidently tackle the toughest, largest-diameter drilling challenges. This core bit is specifically designed for effective wet drilling in cured concrete with rebar, hard masonry, brick block, stucco, and stone. Water cooling is essential for extending tool life, managing heat, and ensuring efficient, clean cuts in these demanding substrates. Flat Segment Design for Superior Chip Evacuation & Stable Cutting：Experience enhanced performance in large-diameter drilling with the advanced flat segment design. This structure promotes efficient removal of drilling debris, significantly reducing the risk of clogging and overheating. Combined with precisely engineered saw teeth and a concentric axis, it ensures smooth, vibration-free cutting and sustained high efficiency. Robust Construction for Demanding Use with Handheld & Rig Drills：Built to handle the rigors of large-bore work. Designed for stable operation, the bit facilitates starting at a 15° angle before transitioning to vertical. It is highly recommended for use with powerful handheld core drills and, optimally, dedicated core drill rigs to manage the significant torque and ensure safety and precision. Essential for Major Large-Diameter HVAC, Plumbing & Construction Projects：The definitive tool for critical large-scale installations. This 5-inch diamond core bit is indispensable for installing large air conditioning units, major plumbing stacks, large-diameter pipes, stair railings, and other substantial fixtures in concrete, brick, masonry, and stone. It's the top choice for professionals on major construction, renovation, and MEP projects.
