Built to DIN 1897 standards from M2 high-speed steel with an oxide finish, it features a 118-degree standard point angle and a web-thinned, tapered web configuration for reduced thrust and cleaner entry. The decimal inch diameter is 0.1890 inches (wire size 12), with an overall length of 2.4409 inches (62.00 mm) and a straight cylindrical shank. The compact stub-length body suits applications where rigidity and minimal deflection matter more than deep reach.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for production and maintenance work on ferrous materials, including steel and cast iron. The stub-length format is common in screw machine operations, CNC drilling fixtures, and short-travel drill press setups where a standard jobber-length bit would flex or chatter. The 2-flute regular spiral design provides efficient chip evacuation at typical feed and speed rates for HSS tooling. It is sold as a single unit and is appropriate for machinists, toolroom technicians, and industrial maintenance professionals.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDIN 1897 stub-length format for improved rigidity over jobber-length bits\u003c\/li\u003e\n\u003cli\u003eM2 high-speed steel construction with oxide finish for corrosion resistance and reduced friction\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle with web-thinned, tapered web for reduced entry thrust\u003c\/li\u003e\n\u003cli\u003e2-flute regular spiral design optimized for steel and cast iron chip evacuation\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank at 0.1890 inches (4.80 mm) for standard chuck compatibility\u003c\/li\u003e\n\u003cli\u003eMaximum drilling depth of 0.7400 inches (18.80 mm)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style stub-length drill bit per DIN 1897 specification, suitable for use in standard drill chucks, CNC turrets, and screw machine spindles accepting a 0.1890-inch straight shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit is installed by a machinist or toolroom technician in any chuck or collet sized for a 0.1890-inch straight shank. Ensure the machine spindle is fully stopped and the chuck is secure before changing tooling. Use appropriate cutting fluid or coolant for steel workpieces to extend tool life, noting this bit does not have through-coolant capability. Verify spindle speed and feed rate are appropriate for HSS tooling in the workpiece material before commencing drilling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 12\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.1890 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: M2 High-Speed Steel (HSS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\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\u003eFlute Length\u003c\/strong\u003e: 26.00 mm (1.024 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.4409 inches (62.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1890 inches (4.80 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.4173 inches (36.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.7400 inches (18.80 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, 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\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: Steel, Cast Iron\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\u003eSeries\u003c\/strong\u003e: 223\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 1897\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.015 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: 9002230048000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51738714374450,"sku":"9002230048000","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/904dac180efa792669a11db9279f6fd4_8e18e5e8-cf73-424b-9289-77037ba016ba.jpg?v=1788803275","url":"https:\/\/voomisupply.com\/products\/guhring-9002230048000-stub-drill-bit-size-12-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
