Built to DIN 1897 standards, it features a 5\/32-inch (0.1563 inch) diameter with a 130-degree split point and a web-thinned, tapered web configuration that reduces thrust and improves chip evacuation. The M35 cobalt steel construction with oxide tip coating provides heat resistance and edge retention when cutting hard or abrasive materials. With a 2-flute regular spiral design and straight-cylindrical shank, this bit is suited for production drilling in machine tools, CNC lathes, and drill presses operated by machinists and tool-room technicians.\u003c\/p\u003e\n\u003cp\u003eThis bit is optimized for drilling titanium alloys and similarly hard workpiece materials where standard high-speed steel bits lose their edge prematurely. The stub-length (3xD flute-to-diameter ratio) body increases rigidity and reduces deflection in short-reach applications, making it a practical choice for screw machine work, production shops, and precision hole-making setups where tight tolerances are required. The straight-cylindrical shank fits standard drill chucks without modification.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM35 cobalt steel construction with oxide tip coating for heat resistance in hard-material drilling\u003c\/li\u003e\n  \u003cli\u003e130-degree split point reduces walking and lowers required feed force at entry\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web configuration improves chip flow and reduces thrust\u003c\/li\u003e\n  \u003cli\u003eStub-length (screw machine length) body increases rigidity and minimizes deflection\u003c\/li\u003e\n  \u003cli\u003eDIN 1897 standard construction for consistent dimensional accuracy\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance of +0.000 to -0.018 mm for precise hole sizing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style stub-length drill bit suitable for standard drill chucks and collet systems accepting a straight-cylindrical shank. Primary workpiece material compatibility is titanium alloy; the cobalt M35 construction also suits stainless steel and other hard ferrous and non-ferrous metals in general production drilling applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use of this drill bit should be performed by qualified machinists or tool-room personnel familiar with proper speeds, feeds, and coolant practices for cobalt tooling. Secure the shank fully in the drill chuck or collet before operation and verify runout is within acceptable limits. Do not use cutting fluid systems that are incompatible with oxide-coated tooling; consult the cutting fluid manufacturer when in doubt. Follow all applicable shop safety standards and machine guarding requirements during use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Fractional)\u003c\/strong\u003e: 5\/32 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal)\u003c\/strong\u003e: 0.1563 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt (M35)\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: Regular Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.1654 inches (55.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.8661 inches (22.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.2992 inches (33.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3.97 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.8661 inches (22.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute-to-Diameter Ratio\u003c\/strong\u003e: 3xD\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\u003eCoating\/Finish\u003c\/strong\u003e: Oxide (Tip)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Web-Thinned, Tapered\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\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: Titanium Alloy\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\u003eStandard\u003c\/strong\u003e: DIN 1897\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 329\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.011 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: 9003290039700\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51730537447730,"sku":"9003290039700","price":16.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/057bc2e01ab6f0f341d519cff7279995.jpg?v=1788719189","url":"https:\/\/voomisupply.com\/products\/guhring-9003290039700-cobalt-stub-drill-bit-5-32-in","provider":"Voomi Supply","version":"1.0","type":"link"}
