Built from high-speed steel (HSS) with a bright, uncoated finish, it features a 130-degree cone relief point and a parabolic flute geometry that promotes fast chip evacuation and reduces cutting resistance. The bit measures 1-15\/16 inches overall length with a 0.6875-inch flute length and a 0.1200-inch cutting diameter. Web thinning at the tip lowers thrust force and improves hole entry. This is a precision ground tool conforming to DIN 1897 and is suited for production and maintenance drilling applications.\u003c\/p\u003e\u003cp\u003eThis bit is intended for use in screw machine, CNC, and bench drill press setups where a compact stub-length tool is required for rigidity and control in short-depth holes. It is appropriate for residential, commercial, and industrial maintenance work where drilling into steel or non-ferrous stock is routine. The maximum drilling depth is 0.5290 inches, making it well-suited for through-hole and shallow blind-hole work in plate, bar stock, or structural members. Licensed machinists, tool-and-die technicians, and HVAC or plumbing tradespeople using metalworking equipment will find this bit a reliable production-grade option.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHSS construction with bright, uncoated finish for general-purpose metal drilling\u003c\/li\u003e\n\u003cli\u003e130-degree cone relief point reduces walking and improves hole entry accuracy\u003c\/li\u003e\n\u003cli\u003eParabolic flute with fast spiral promotes efficient chip removal in deep cuts\u003c\/li\u003e\n\u003cli\u003eWeb-thinned parallel web lowers axial thrust and extends tool life\u003c\/li\u003e\n\u003cli\u003eStub length (1-15\/16 inches OAL) provides added rigidity over jobber-length bits\u003c\/li\u003e\n\u003cli\u003eConforms to DIN 1897 standard for consistent dimensional accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or production tooling option for standard straight-shank drill chucks accepting a 0.1201-inch shank diameter.

Ensure the chuck is fully tightened and the spindle is at a complete stop before changing bits. Select a spindle speed appropriate for the workpiece material and bit diameter following standard machining feeds-and-speeds references. Do not exceed the 0.5290-inch maximum drilling depth in a single pass without retracting to clear chips.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 31\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.1200 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-15\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.6875 inches (45\/64 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1201 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.2205 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.5290 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\u003ePoint Type\u003c\/strong\u003e: Cone Relief\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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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 (Screw Machine Length)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute-to-Diameter Ratio\u003c\/strong\u003e: 3xD\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: 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\u003eUNSPSC Code\u003c\/strong\u003e: 23241635\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: 9005520030500\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51755316937010,"sku":"9005520030500","price":17.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bfc6da9a9954e2a9acfed0c1a3e6ee2e.jpg?v=1788953524","url":"https:\/\/voomisupply.com\/products\/guhring-9005520030500-stub-drill-bit-size-31-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
