Built from high speed steel with a bright, uncoated finish, it features a 135-degree split-point tip that reduces walking and improves bite on curved or hardened surfaces. The parabolic flute geometry with web thinning promotes efficient chip evacuation and lowers cutting resistance. At 7.625 inches overall length with a 5.625-inch flute, this bit suits standard drill press and handheld power drill applications. It is typically installed by machinists, maintenance technicians, pipefitters, and HVAC fabricators working in metal fabrication and field drilling tasks.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is rated for use in steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. The straight cylindrical shank at 0.6875 inches diameter fits standard three-jaw chucks without adapters. The Series QC21P designation places it in a heavy-duty jobber category, making it appropriate for production drilling environments as well as single-use field applications. The 8xD flute-to-diameter ratio supports drilling depth up to 5.625 inches in a single pass under proper chip-clearing conditions.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e135-degree split point reduces tip walking and improves penetration on hard or curved surfaces\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction handles steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium\u003c\/li\u003e\n  \u003cli\u003eParabolic spiral flute with web thinning for efficient chip evacuation and reduced heat buildup\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank at 11\/16 inches fits standard drill chucks without adapters\u003c\/li\u003e\n  \u003cli\u003e7.625-inch overall length with 5.625-inch maximum drilling depth suits most jobber-length applications\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI standards; heavy-duty grade rated for general-purpose production and field use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose jobber-length drill bit compatible with any standard three-jaw drill chuck accepting an 11\/16-inch straight cylindrical shank, including drill presses and handheld power drills used in metal fabrication, HVAC, plumbing, and electrical trade work.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSecure the shank fully in a properly sized drill chuck and confirm chuck key is removed before operation. Apply appropriate cutting fluid when drilling stainless steel, superalloys, or titanium to manage heat and extend tool life. Reduce feed pressure as the tip breaks through to prevent bit grab or workpiece movement.
