It is designed for general-purpose hole-making in metalworking and fabrication environments. The 118-degree standard point angle and web-thinned tip promote clean entry and reduce walking on ferrous materials. With an overall length of 4-5\/8 inches and a flute length of 3-5\/16 inches, this bit fits standard drill chucks and drill presses used by machinists, maintenance technicians, and metalworking tradespeople.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for drilling cast iron and steel in production and maintenance applications. The straight-cylindrical shank accommodates standard three-jaw chucks without modification. The regular spiral flute geometry supports chip evacuation at typical feed-and-speed parameters for HSS tooling. It conforms to DIN 338, making it dimensionally interchangeable with other jobber-length bits built to that standard. Single-piece packaging makes it practical for bench stock replenishment or individual job use.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLetter P sizing — 0.3230 inches decimal equivalent, with a diameter tolerance of -0.0010 to 0.0000 inches\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction with titanium nitride (TiN) coating for improved surface hardness and wear resistance\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle with web-thinned, tapered web for reduced thrust and cleaner starts\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, regular spiral flute, 2-flute configuration for efficient chip removal\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank (0.3230 inches) fits standard drill chucks without adapters\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 338 jobber-length standard\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose jobber-length drill bit for use in steel and cast iron.
