Built from powdered metal with a coated finish, this bit runs a 2-flute parabolic spiral configuration that promotes efficient chip evacuation in deep-hole and production drilling applications. The 130-degree split-point geometry with web thinning and cone relief reduces thrust force and improves centering without a pilot hole. At 2.7559 inches overall length and a 1.2205-inch flute length, it fits standard drill chucks and quick-change systems used on drill presses, CNC lathes, and screw machines.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for production drilling in cast iron and steel in both job-shop and automated machining environments. The stub-length body provides added rigidity over jobber-length bits, making it a reliable choice when minimizing deflection in short, repeated drilling cycles. The straight-cylindrical shank seats securely in collet chucks and standard drill press spindles. It conforms to DIN 1897 standards and carries an h8 diameter tolerance for consistent, repeatable hole sizing. Machinists, tool-and-die shops, and maintenance technicians working with ferrous stock are the primary users.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eParabolic flute geometry with fast spiral for aggressive chip removal in steel and cast iron\u003c\/li\u003e\n  \u003cli\u003e130-degree cone-relief point with web thinning reduces entry thrust and self-centers on contact\u003c\/li\u003e\n  \u003cli\u003ePowdered metal construction with coating for extended tool life in production environments\u003c\/li\u003e\n  \u003cli\u003eStub-length body (2.7559 inches OAL) adds rigidity and reduces deflection versus jobber bits\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard collet chucks and drill press spindles without adapters\u003c\/li\u003e\n  \u003cli\u003eDIN 1897 compliant with h8 diameter tolerance for consistent hole sizing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for drilling cast iron and steel.

Secure the shank fully in the chuck or collet before operation and verify runout before drilling production parts. Ensure the workpiece is clamped or fixtured to prevent rotation. Do not exceed the recommended maximum drilling depth of 0.8640 inches per pass without retracting to clear chips.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.2378 inches (Letter Size B)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 130 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.7559 inches (70.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.2205 inches (31.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.8640 inches (21.94 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Parabolic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Fast (3xD Flute-to-Diameter Ratio)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Powdered Metal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Coated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Cone Relief\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Treatment\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Stub (Screw Machine Length)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: h8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 515\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 1897\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.025 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: GUHRING\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 9005150060400\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51729247338802,"sku":"9005150060400","price":37.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bbe102cf79a0c87a2f3cab70a6ecfed3_8a3f804a-dc31-4a19-aab8-449de3932433.jpg?v=1788702193","url":"https:\/\/voomisupply.com\/products\/guhring-9005150060400-screw-machine-drill-bit-0-2378in","provider":"Voomi Supply","version":"1.0","type":"link"}
