Built from high-speed steel (HSS) with a bright, uncoated finish, this bit features a parabolic flute geometry and a 130-degree cone relief point for improved chip evacuation and reduced thrust force in short-hole applications. The web-thinned, parallel web construction reduces cutting resistance at the chisel edge. Overall length is 2-29\/32 inches, making it well suited for close-quarters drilling where standard-length bits are impractical. Installed by machinists and metalworking tradespeople, this bit meets DIN 1897 specifications.\u003c\/p\u003e\u003cp\u003eThis drill bit is intended for stub-length drilling applications in metal fabrication, production machining, and maintenance environments. Its right-hand cutting direction and parabolic fast-spiral flute design promote efficient swarf removal when drilling steel and non-ferrous alloys. The straight cylindrical shank is compatible with standard drill chucks and collet holders. With a maximum drilling depth of 0.9400 inches and a 3xD flute-to-diameter ratio, it is optimized for short, accurate holes in ferrous and non-ferrous workpieces rather than deep-hole operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHSS construction with bright, uncoated finish for use in steel, aluminum, and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003e130-degree cone relief point with web thinning reduces thrust and improves hole entry accuracy\u003c\/li\u003e\n\u003cli\u003eParabolic fast-spiral flute design promotes rapid chip evacuation in short-depth drilling\u003c\/li\u003e\n\u003cli\u003eStub length (2-29\/32 inches OAL) for use in confined or close-tolerance setups\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank fits standard drill chucks and collet holders\u003c\/li\u003e\n\u003cli\u003eMeets DIN 1897 specification; Series 552 high-performance grade\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a DIN 1897-compliant stub-length drill bit suitable for use in standard drill presses, CNC machining centers, and hand-held drill equipment with compatible straight-shank chuck capacity in the 0.2500 to 0.3000 inch diameter range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use of this drill bit should be performed by qualified machinists or metalworking tradespeople familiar with cutting tool setup and safe machine operation. Ensure the spindle or drill chuck is fully powered down and the machine is locked out before loading or changing the bit. Verify chuck or collet capacity accommodates the 0.2656-inch shank diameter before tightening. Follow applicable workplace safety standards and machine manufacturer guidelines for feed rate and spindle speed selection when drilling the target workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.2657 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Fractional Inch)\u003c\/strong\u003e: 17\/64 inches\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 Point Angle\u003c\/strong\u003e: 130 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Cone Relief\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\u003eOverall Length\u003c\/strong\u003e: 2-29\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-11\/32 inches (34.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2656 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.5748 inches (40.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.9400 inches (23.88 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel, Web-Thinned\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 -0.022 mm\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\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\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 9005520067500\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51744812794162,"sku":"9005520067500","price":30.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c1e1751ba374d8ffed64c80d9b29fd33.jpg?v=1788860807","url":"https:\/\/voomisupply.com\/products\/guhring-9005520067500-drill-bit-letter-h-hss-130-deg","provider":"Voomi Supply","version":"1.0","type":"link"}
