Meet the Diablo DMAPLCC1110 3-7/8" SDS-Plus Carbide Tipped Thin Wall Core Bit — a purpose-built solution for fast, reliable concrete coring. Built for professional use in both corded and cordless SDS-Plus rotary hammers, this bit is engineered to deliver quick, clean cores and lasting performance in tough concrete, masonry, and brick jobs.

What sets this core bit apart is Diablo’s meticulous edge—carbide tips brazed and hardened through a proprietary process. The result is exceptional wear resistance, longer tool life, and sustained cutting efficiency even as you tackle dense substrates. The thin-wall design paired with precision brazing minimizes resistance, enabling faster hole creation without sacrificing core integrity.

Two ejector holes streamline core removal, reducing downtime between holes so you can keep your workflow flowing on busy jobsites. This feature is especially valuable when drilling large-diameter cores or working in tight spaces where snagging or stuck cores slows progress.

Key benefits you’ll notice on the job

• Rapid, clean cores: Thin-wall construction and carbide-tipped edge work together for swift hole-making with precise diameters.
• Durable carbide tips: Advanced brazing and hardening extend tip life, helping you complete more cores before retooling.
• Easy core removal: Dual ejector holes reduce effort and downtime when extracting the drilled core.
• Optimized for SDS-Plus hammers: Designed to perform consistently in both corded and cordless SDS-Plus rotary hammers, giving you reliable power across job sites.
• Concrete and masonry specialist: Ideal for large-diameter cores in reinforced concrete, block, and brickwork common in construction, remodeling, and retrofit projects.

Use scenarios include electrical and plumbing rough-ins, conduit and pipe installations in new builds, or retrofits where precise, sizable cores through dense concrete are required. For best results, pair the DMAPLCC1110 with a compatible SDS-Plus hammer, maintain steady feed pressure, and select an appropriate drilling speed to maximize carbide longevity and core quality.
