Built from high-speed steel with an oxide coating, this bit features a parabolic flute design and a 130-degree split point for improved chip evacuation and reduced thrust in production drilling applications. The straight-cylindrical shank seats directly in standard drill chucks. With a web-thinned, tapered web configuration and an 8xD flute-to-diameter ratio, this bit is engineered for high-performance drilling where consistent hole quality and tool life matter. It is sized and toleranced to h8 shank standards and meets ANSI and ISO specifications.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for drilling cast iron, non-ferrous metals, and steel in both blind-hole and stack-drilling applications. The parabolic flute geometry accelerates chip removal in deeper passes, making it a practical choice for production environments and repetitive drilling cycles. No coolant-through capability is present, so conventional flood or mist cooling applies where needed. The Series A1222 designation places this in a family of high-performance jobber drills intended for use by machinists, millwrights, and tool-and-die professionals.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWire gauge size 21 (0.1590 inches) with h8 shank diameter tolerance for precise chuck fit\u003c\/li\u003e\n  \u003cli\u003e130-degree standard point angle with web-thinned, tapered web for reduced entry thrust\u003c\/li\u003e\n  \u003cli\u003eParabolic flute geometry with 8xD flute-to-diameter ratio for fast chip evacuation\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction with oxide coating for surface hardness and heat resistance\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, straight-cylindrical shank compatible with standard drill chucks\u003c\/li\u003e\n  \u003cli\u003eRated for blind-hole and stack-drilling applications on cast iron, non-ferrous metal, and steel\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard drill chucks accepting a 0.1590-inch straight-cylindrical shank.
