Part of the Series 515 lineup, it measures 0.0785 inches (Wire Size 47) in diameter with an overall length of 1.4961 inches and a flute length of 0.4724 inches. The bit is manufactured from powdered metal and features a parabolic fast-spiral flute geometry with web thinning, which promotes efficient chip evacuation and reduces thrust in short-hole applications. The 130-degree point angle and cone relief point type suit it to harder ferrous workpiece materials commonly encountered in production machining and maintenance repair operations.\u003c\/p\u003e\u003cp\u003eThis drill bit is intended for use in screw machine operations, CNC drilling centers, and handheld or bench drill press applications where a compact stub-length tool is required. Its straight-cylindrical shank seats directly in standard drill chucks and collets without modification. The right-hand cut, parabolic flute design makes it well suited for production runs in cast iron and steel components, including structural fabrication and mechanical assembly work. It ships individually and carries a minimum order quantity of 10 units, making it appropriate for shop stocking in production environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePowdered metal construction provides elevated hardness and wear resistance compared to standard high-speed steel\u003c\/li\u003e\n\u003cli\u003eParabolic fast-spiral flute promotes rapid chip removal and reduced heat buildup in ferrous materials\u003c\/li\u003e\n\u003cli\u003eWeb-thinned point reduces axial thrust and improves centering at drill entry\u003c\/li\u003e\n\u003cli\u003e130-degree included point angle optimized for cast iron and steel workpieces\u003c\/li\u003e\n\u003cli\u003eStub flute length (0.4724 inches) and compact overall length (1.4961 inches) add rigidity and minimize deflection\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank is compatible with standard chucks and collets\u003c\/li\u003e\n\u003cli\u003eConforms to DIN 1897 standard with h8 diameter tolerance for consistent fitment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a DIN 1897 stub-length screw machine drill bit suitable for use in standard drill chucks, collets, and screw machine spindles accepting a straight-cylindrical shank in the 0.0785-inch diameter range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by a machinist or qualified trade professional familiar with rotating cutting tools. Secure the shank fully in the chuck or collet and verify concentricity before operation. Always power down and lock out the machine before changing or inspecting the bit. Do not exceed the maximum recommended drilling depth of 0.3550 inches per pass without retracting to clear chips.\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: 1.4961 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.4724 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.3550 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\u003eSpiral Type\u003c\/strong\u003e: Fast\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Parabolic\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 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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Steel\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: h8\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\u003ePackage Dimensions\u003c\/strong\u003e: 3 inches x 2 inches x 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.025 pounds\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: 9005150019900\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51728694116658,"sku":"9005150019900","price":171.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bbe102cf79a0c87a2f3cab70a6ecfed3_48d1445b-9d1f-4123-a196-5bd9b9af53bc.jpg?v=1788695141","url":"https:\/\/voomisupply.com\/products\/guhring-9005150019900-screw-machine-drill-bit-0-0785in","provider":"Voomi Supply","version":"1.0","type":"link"}
