Built from high-speed steel (HSS) with a bright uncoated finish, it features a 3\/16-inch diameter, a 130-degree cone-relief point, and a parabolic flute geometry that promotes fast chip evacuation and reduces heat buildup at the cutting edge. The web-thinned tip lowers entry resistance on harder workpiece materials. At 2-7\/16 inches overall length with a 1-1\/32-inch flute, this stub-length bit provides added rigidity compared to jobber-length equivalents, making it well-suited for drill press and CNC applications where deflection control matters.\u003c\/p\u003e\u003cp\u003eThis bit is intended for drilling steel, aluminum, and non-ferrous metals. The stub-length format is a standard choice in screw machine operations, short-hole drilling fixtures, and any setup where a shorter, stiffer bit improves hole location accuracy. The straight cylindrical shank accepts standard drill chucks without modification, and the right-hand cutting direction suits conventional drill press and lathe tailstock use. Machinists, toolroom technicians, and maintenance mechanics working in production or fabrication shops are the primary users. It conforms to DIN 1897 specification for stub-length drills.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHSS construction with bright uncoated finish suitable for general-purpose metal cutting\u003c\/li\u003e\n\u003cli\u003e130-degree cone-relief point angle for aggressive entry on steel and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eParabolic fast-spiral flute design promotes efficient chip removal and reduces chip packing\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tip reduces thrust force required at drill entry\u003c\/li\u003e\n\u003cli\u003eStub length (DIN 1897 Series 552) provides greater rigidity than jobber-length bits\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank fits standard drill chucks; no adapter required\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use stub drill conforming to DIN 1897 standards, compatible with any drill press, CNC machining center, or lathe tailstock chuck accepting a 3\/16-inch straight shank.

Secure the shank fully in the chuck and verify runout before drilling. Always power down and lock out the machine before changing tooling. Cutting fluid or coolant is recommended for steel applications to extend tool life, even though this bit does not feature through-coolant capability.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 3\/16 inches (0.1875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-7\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-1\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.743 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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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 Configuration\u003c\/strong\u003e: Parallel, Web-Thinned\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\u003eDrill Length Type\u003c\/strong\u003e: Stub\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 -0.018 mm\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\u003eCoolant Through\u003c\/strong\u003e: No\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\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: 9005520047600\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51727219425586,"sku":"9005520047600","price":21.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1f6584a2dec3d87de4d78ef2976d0ae1.jpg?v=1788674874","url":"https:\/\/voomisupply.com\/products\/guhring-9005520047600-screw-machine-drill-bit-3-16in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
