Built around a robust tapered core, it resists flute breaks under heavy load — a common failure point on lesser bits. The two-stage flute design runs a variable helix pattern that actively clears debris from the bore as drilling progresses, keeping the cutting zone clean and reducing heat buildup. Two sharp carbide cutting edges produce round, accurate holes suited for anchor installation. Manufactured in Germany, this bit is backed by a No Break Guarantee.\u003c\/p\u003e\n\u003cp\u003eThis bit is sized at 3\/8 inch by 4 inch overall and is intended for use with SDS-plus chuck rotary hammer drills. It targets applications where secure, clean anchor holes are required — structural fastening, mechanical system rough-in, electrical conduit anchoring, and concrete fixture mounting. The package quantity is 25 bits per unit, making it practical for volume work on commercial or residential job sites where anchor installation volume is high.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTapered core construction resists flute breaks during deep hole drilling\u003c\/li\u003e\n  \u003cli\u003eTwo-stage variable helix flute design for rapid debris clearing\u003c\/li\u003e\n  \u003cli\u003eDual carbide cutting edges for clean, round hole geometry\u003c\/li\u003e\n  \u003cli\u003eSDS-plus shank for positive chuck engagement without a chuck key\u003c\/li\u003e\n  \u003cli\u003eManufactured in Germany with No Break Guarantee\u003c\/li\u003e\n  \u003cli\u003eSold in a 25-piece package for high-volume anchor installation work\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with SDS-plus rotary hammer drills for anchor hole drilling in concrete, block, and masonry applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall this bit into any SDS-plus rotary hammer drill — confirm the bit seats and locks fully before operating.
