Built around a 4-cutter, full-carbide head, this bit is manufactured using tri-metal diffusion bonding technology, which bonds the carbide head to the steel shank to resist heat buildup and prevent tip breakage under sustained load. The precision-ground tip delivers stable, accurate hole starts, making it well-suited for ANSI-approved anchor setting applications. Licensed tradespeople working concrete-heavy jobs will find this bit handles both the rotational stress of high-powered hammer drills and the impact shock of cutting through embedded rebar.\u003c\/p\u003e\u003cp\u003eThis bit is designed for use in corded and cordless SDS-Plus and SDS-Max rotary hammer drills. Primary applications include drilling anchor holes in reinforced concrete slabs, walls, and foundations in both residential and commercial construction. The 7\/8 inch cutting diameter and 10 inch overall length make it appropriate for through-bolt and anchor rod installations where deeper reach is required. Electricians, plumbers, concrete contractors, and general tradespeople working in reinforced concrete environments are the typical end users. This product is sold in a package quantity of 10 bits.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4-cutter full-carbide head for faster cutting and extended durability in reinforced concrete\u003c\/li\u003e\n\u003cli\u003eTri-metal diffusion bonding technology bonds carbide to shank, reducing heat buildup and breakage risk\u003c\/li\u003e\n\u003cli\u003ePrecision tip geometry supports accurate hole starts and ANSI-compliant anchor setting\u003c\/li\u003e\n\u003cli\u003eCompatible with corded and cordless SDS-Plus and SDS-Max rotary hammers\u003c\/li\u003e\n\u003cli\u003eFull-carbide head construction withstands rebar impact without tip failure\u003c\/li\u003e\n\u003cli\u003ePackage quantity of 10 bits for job-site supply\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eOptimized for maximum performance in corded and cordless SDS-Plus and SDS-Max rotary hammers.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall and remove SDS-Plus bits only with the hammer drill powered off and unplugged or battery removed. Confirm the chuck mechanism is fully seated before beginning drilling. Eye protection and hearing protection are required when operating rotary hammer equipment in concrete.
