Ground from high speed steel (HSS) with an oxide finish, it operates at a 4.2 mm (0.1654 inch) diameter with a 118-degree standard point angle. The two-flute spiral design with a tapered web and web-thinned tip reduces walking on entry and promotes clean chip evacuation. The straight-cylindrical shank seats securely in standard drill chucks. At 2.953 inches overall length with a 1.693-inch flute length, it fits the jobber-length form factor used across metalworking, mechanical, and general fabrication work.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for drilling mild steel, aluminum, and similar materials in general-purpose applications. The Series 2001G construction meets ASME B94.11M and DIN 338 standards, making it appropriate for trade shops, field service kits, and production drilling where consistent tolerances matter. The 4xD flute-to-diameter ratio supports adequate chip clearance in through-hole drilling at typical hand or machine feed rates.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4.2 mm (0.1654 inch) diameter with diameter tolerance of -0.0007 to 0.0000 inches for consistent hole sizing\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle with web-thinned, tapered web for reduced entry thrust\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction with oxide coating for wear resistance in general-purpose drilling\u003c\/li\u003e\n  \u003cli\u003eTwo-flute regular spiral geometry promotes chip evacuation in through-hole applications\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank (0.1654 inch diameter) fits standard keyed and keyless drill chucks\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B94.11M and DIN 338 standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose jobber-length drill bit suitable for use in hand drills, drill presses, and CNC drilling applications requiring a 4.2 mm straight-shank bit conforming to DIN 338 and ASME B94.11M specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall in a properly sized drill chuck and verify the shank is fully seated before operation. Power down or de-energize the drilling equipment before changing bits. Use appropriate cutting fluid or lubricant when drilling ferrous materials to extend tool life and maintain hole tolerance.
