Built from high speed steel with a bright, uncoated finish, this bit features a parabolic flute geometry and a web-thinned, parallel web configuration that improves chip evacuation and reduces cutting resistance. The 130-degree split point promotes accurate positioning and self-centering without a center punch on most workpieces. At 0.0785 inches in diameter (Wire Size 47), this bit is designed for precision hole-making at small diameters where dimensional accuracy is critical. Licensed machinists, tool-and-die shops, and production drilling operations are the primary users.\u003c\/p\u003e\u003cp\u003eThis bit is suited for drilling aluminum, aluminum alloy, brass, and steel in production and job-shop environments. The screw machine length format — shorter overall length than a jobber bit — provides added rigidity and reduced deflection in drill press, CNC, and turret lathe setups where short-reach tooling is preferred. The straight-cylindrical shank seats directly into standard drill chucks and collets without adapters. It conforms to DIN 1897 specification, making it a recognized standard for stub-length tooling in both domestic and international machine shops.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eParabolic flute geometry promotes fast chip evacuation in deep-hole and production drilling\u003c\/li\u003e\n\u003cli\u003e130-degree point angle with web thinning improves self-centering and reduces thrust force\u003c\/li\u003e\n\u003cli\u003eDIN 1897 specification ensures dimensional conformance to international stub-length standards\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction provides toughness across aluminum, brass, and steel workpieces\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish allows visual wear monitoring during service life\u003c\/li\u003e\n\u003cli\u003eScrew machine length body adds rigidity and minimizes deflection at small diameters\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a stub-length replacement or production drill for use in standard drill chucks and collets accepting a straight-cylindrical shank at 0.0785 inches diameter, conforming to DIN 1897 geometry in Series 552.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit is installed and replaced by machinists, tool-and-die technicians, and CNC setup personnel. Secure the shank fully in the chuck or collet and verify runout before production use, as small-diameter bits are sensitive to chuck concentricity. Power down all spindle drives and lock out the machine before changing tooling. Avoid side-loading or prying with the bit, as small-diameter HSS is brittle under lateral force.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.0785 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire Size\u003c\/strong\u003e: 47\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 15\/32 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\u003eTool Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Parabolic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0.000 to -0.014 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Aluminum, Aluminum Alloy, Brass, Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: DIN 1897\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 552\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: High Performance\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: 9005520019900\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51748739121458,"sku":"9005520019900","price":89.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d68f0cd5f88e7695f6d2e70cfa6b2c29.jpg?v=1788897585","url":"https:\/\/voomisupply.com\/products\/guhring-9005520019900-screw-machine-drill-bit-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
