It features a 140-degree R-thinned point that promotes self-centering and reduces thrust on entry. The EgiAs multi-layer coating improves wear resistance and heat dissipation during aggressive material removal. With an overall length of 4.0551 inches (103.00 mm) and a 2.4016-inch (61.00 mm) flute length, this drill is suited for production environments where tool life and hole accuracy are critical. Installation is performed by machinists and CNC operators working in metalworking, fabrication, and maintenance repair applications.\u003c\/p\u003e\n\u003cp\u003eThe HP245-3228 is built for drilling blind holes, through holes, and cross holes in steel and cast iron workpieces. Its 5xD flute-to-diameter ratio supports chip evacuation in moderate-depth holes. The straight cylindrical shank with a 10 mm shank diameter accommodates standard drill chucks and collet holders. Right-hand cutting direction and regular spiral flute geometry make this a direct fit for conventional CNC machining centers, drill presses, and handheld power tools used in metalworking trades.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and extended tool life in ferrous materials\u003c\/li\u003e\n  \u003cli\u003e140-degree R-thinned point promotes self-centering and reduces walking on entry\u003c\/li\u003e\n  \u003cli\u003eEgiAs multi-layer proprietary coating for improved wear resistance and thermal protection\u003c\/li\u003e\n  \u003cli\u003eSuitable for blind hole, cross hole, and self-centering drilling applications\u003c\/li\u003e\n  \u003cli\u003eTapered web configuration with R-thinned web reduces cutting force\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through design simplifies setup on standard spindles\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for drilling steel and cast iron workpieces (ISO material groups P and K).
