Diablo DMAPLCC1100 3-1/2" SDS-Plus Carbide Tipped Thin Wall Core Bit is built to power through concrete with precision and longevity. This is not your average core bit—the DMAPLCC1100 belongs to Diablo’s SDS-Plus Thin Wall Core Bit line, engineered for one of the fastest, longest-lasting coring experiences you can get in masonry drilling. What makes this bit standout - Carbide-tipped durability: The tips are optimized with a proprietary brazing and hardening process, delivering extended life and sustained performance even in tough concrete mixes. - Fast, clean cores: Designed to cut quickly while producing tight, clean holes that are ideal for anchors, sleeves, and conduit runs. - Easy core removal: Two ejector holes streamline core extraction, reducing downtime and keeping your workflow smooth. - Corded or cordless versatility: Optimized for maximum performance in both corded and cordless SDS-Plus rotary hammers, so you can rely on consistent results across tools. Who benefits most - Professional trades: electricians running large conduit, plumbers laying pipe, masons core-drilling for anchors, and general contractors tackling heavy concrete work will appreciate the efficiency and reliability. - Renovation and new construction projects alike: when fast, accurate hole sizes matter for quick installations and clean finishes. Why it matters in your project - Faster throughput means fewer tool changes and less downtime, accelerating schedules without sacrificing precision. - The thin-wall design, paired with carbide tips, yields robust performance across repeated core cuts, helping crews stay on task from start to finish. Practical use scenarios - Drilling large-diameter holes in poured concrete to accommodate anchors and sleeves for structural or retrofit installations. - Creating clean conduits for electrical or plumbing runs where durable, long-lived cores are essential. - Overhead or tight-access core drilling where a reliable, high-performance bit minimizes wear and resharpening needs. Tips for best results - Use in an SDS-Plus rotary hammer (corded or cordless) that matches the bit size and material hardness you’re drilling. - Let the bit do the work: apply steady pressure and steady RPM for consistent core formation, and pause to remove the core with the ejector holes as needed. - Confirm compatibility with your drill setting and avoid pushing beyond the bit’s designed diameter and depth to maximize bit life. The Diablo DMAPLCC1100 3-1/2" SDS-Plus Carbide Tipped Thin Wall Core Bit is the choice for professionals who demand fast drilling, cleaner holes, and longer bit life in demanding concrete applications. If you’re upgrading your core-drilling toolkit, this bit delivers reliable performance where it counts.
