Built from high-speed steel (HSS) with a bright, uncoated finish, it features a parabolic flute geometry that promotes fast chip evacuation and reduces heat buildup during cutting. The 130-degree split-point cone relief tip improves self-centering on entry and reduces thrust force compared to standard 118-degree points. The right-hand cutting direction and web-thinned construction make it well-suited for drilling steel, aluminum, and other non-ferrous materials. Machinists, tool-and-die workers, and maintenance mechanics are the primary installers of this bit.\u003c\/p\u003e\u003cp\u003eThis drill bit is sized at 3\/8 inches (0.3750 inches decimal) with a matching straight cylindrical shank diameter of 0.3750 inches and an overall length of 3.5 inches, placing it in the stub-length category for increased rigidity in short-reach applications. The parabolic flute, rated at a 3xD flute-to-diameter ratio, makes this bit effective in drill presses, CNC machining centers, and hand-held power tools where chip clearing is critical. It is built to DIN 1897 specification and is appropriate for production drilling in steel and aluminum workpieces where hole accuracy and cycle time matter.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e130-degree cone relief point with web thinning for improved self-centering and reduced entry thrust\u003c\/li\u003e\n\u003cli\u003eParabolic flute geometry with fast spiral promotes efficient chip evacuation in deep-hole drilling\u003c\/li\u003e\n\u003cli\u003eHSS construction provides toughness and re-sharpenability for general metalworking applications\u003c\/li\u003e\n\u003cli\u003eStub-length (screw machine length) body increases rigidity and reduces deflection versus jobber-length bits\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank fits standard drill chucks without adapters\u003c\/li\u003e\n\u003cli\u003eConforms to DIN 1897 specification for consistent dimensional accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a DIN 1897-compliant screw machine length drill bit suitable for use in standard 3\/8-inch capacity drill chucks on drill presses, CNC machining centers, and hand-held power tools.

Ensure the drill press or machine spindle is fully powered down and locked out before changing tooling. Use appropriate cutting fluid or coolant when drilling steel to extend tool life, noting this bit does not have through-coolant capability. Secure the workpiece firmly to prevent rotation and verify drill chuck runout is within acceptable tolerances before starting a production run.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 3\/8 inches (0.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-11\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.1310 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3750 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.8110 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 130 degrees\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Cone Relief\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High-Speed Steel (HSS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0.000 to -0.022 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Aluminum, Non-Ferrous\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 552\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 1897\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 9005520095200\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51745972322610,"sku":"9005520095200","price":42.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/949d3b9c56fef76268163bb27e2c3c82.jpg?v=1788866189","url":"https:\/\/voomisupply.com\/products\/guhring-9005520095200-screw-machine-drill-bit-3-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
