It measures 12.70 mm (0.5000 inch) in diameter with a 118-degree standard point angle and a spiral flute configuration that promotes efficient chip evacuation. Constructed from high speed steel with an oxide coating, this drill bit delivers adequate wear resistance for everyday shop and field drilling tasks. The straight-cylindrical shank seats securely in standard drill chucks. With an overall length of 152 mm and a flute length of 114 mm, it handles typical jobber-depth holes without the need for extended-length tooling.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for maintenance, fabrication, and general metalworking applications in both shop and field environments. The 0.5000-inch diameter is a common size across HVAC, plumbing, electrical, and structural trade work where half-inch clearance or pilot holes are required. It is appropriate for use in drill presses, hand drills, and magnetic base drills. Right-hand cutting direction is standard for conventional drilling operations. The bit falls within the 12.50 mm to 15.00 mm size range family, making it a straightforward general-purpose selection for tradespeople who need a reliable half-inch drill.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e12.70 mm (0.5000 inch) diameter with a standard 118-degree point angle for general-purpose entry\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction with oxide coating for improved surface hardness and basic corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eSpiral flute design with 2 flutes promotes chip clearance during drilling\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard 3-jaw drill chucks without adapters\u003c\/li\u003e\n  \u003cli\u003e152 mm overall length with 114 mm flute length  -  standard jobber proportions\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction; no coolant-through feature required for general-purpose use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose jobber drill compatible with any drill press, hand drill, or magnetic base drill accepting a straight-cylindrical shank in the 12.70 mm diameter range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSecure the straight shank fully in the drill chuck and confirm it is centered before operation.
