Built to DIN 1897 standards, this 3\/16 inch diameter bit features a 118-degree standard point angle and a web-thinned geometry that reduces entry force and improves chip evacuation. The straight-cylindrical shank measures 0.1875 inches in diameter and is compatible with standard drill chucks. With an overall length of 2.44 inches and a flute length of approximately 1.02 inches, this short-length design provides rigidity and minimizes deflection in shallow-hole applications. It is intended for use by machinists, maintenance technicians, and fabricators working with cast iron and steel workpieces.\u003c\/p\u003e\n\u003cp\u003eThis stub-length drill bit is suited for production drilling, screw machine operations, and CNC or manual drill press work where a shorter, stiffer tool is preferred over jobber-length alternatives. The 3xD flute-to-diameter ratio and parallel web configuration make it well-matched for repetitive hole operations in ferrous materials, particularly cast iron and steel. The right-hand spiral flutes and 118-degree point geometry are standard for general-purpose drilling in these materials. Maximum drilling depth is 0.743 inches, making this bit appropriate for shallow through-hole and blind-hole applications in production or maintenance settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDIN 1897 stub-length design provides increased rigidity and reduced deflection compared to jobber-length bits\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle with web-thinned tip reduces thrust force on entry\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel (HSS) construction with coated finish for extended tool life in ferrous materials\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank (0.1875 inches diameter) fits standard drill chucks without adapters\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with regular spiral flutes for efficient chip clearing in cast iron and steel\u003c\/li\u003e\n  \u003cli\u003eMaximum drilling depth of 0.743 inches suits shallow through-hole and blind-hole operations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a DIN 1897-compliant stub-length drill bit for use in standard drill chucks, CNC machining centers, and screw machines accepting a 0.1875 inch straight-cylindrical shank.

Ensure the drill chuck is fully tightened and the workpiece is securely fixtured before operation. Always power down the machine and bring the spindle to a complete stop before changing bits or clearing chips. Follow applicable shop safety standards and the machine manufacturer's operating guidelines for speed and feed selection.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 2.44 inches (62 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.02 inches (26 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.42 inches (36 mm)\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 (18.86 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 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: Regular\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\u003eTool Material\u003c\/strong\u003e: High-Speed Steel (HSS)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Coated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel, Web-Thinned\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: +0.000 to -0.018 mm\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\u003eStandard\u003c\/strong\u003e: DIN 1897\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 223\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 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: 9002230047600\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51734575382834,"sku":"9002230047600","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/904dac180efa792669a11db9279f6fd4_009954e3-7aaa-4b23-8a85-65d10dd956f5.jpg?v=1788763527","url":"https:\/\/voomisupply.com\/products\/guhring-9002230047600-screw-machine-drill-bit-3-16in","provider":"Voomi Supply","version":"1.0","type":"link"}
