Built to DIN 1897 standards, this heavy-duty bit features a parabolic flute geometry and a 130-degree split point with web thinning to reduce thrust and improve chip evacuation. The 0.1015-inch (wire size 38) diameter and straight-cylindrical shank suit precision drilling operations in production and maintenance environments. Licensed machinists, tool-and-die technicians, and industrial maintenance professionals use this bit where standard HSS tooling falls short.\u003c\/p\u003e\n\u003cp\u003eThis bit is optimized for drilling titanium alloys and other difficult-to-machine materials where cobalt's elevated heat resistance is required. The parabolic flute profile promotes efficient chip removal in deep-hole applications, and the stub length provides added rigidity in short-reach setups such as screw machine and turret lathe operations. With a 3xD flute-to-diameter ratio and a maximum drilling depth of 0.399 inches (10.13 mm), it is suited for through-holes and blind holes in tight tolerances.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt tool material for heat resistance in titanium alloy and hard-material drilling\u003c\/li\u003e\n  \u003cli\u003e130-degree point angle with web thinning reduces entry thrust and improves centering\u003c\/li\u003e\n  \u003cli\u003eParabolic flute geometry enhances chip evacuation and reduces clogging\u003c\/li\u003e\n  \u003cli\u003eStub length (DIN 1897) provides greater rigidity than jobber-length equivalents\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, straight-cylindrical shank fits standard drill chucks and collets\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance of +0.000 to -0.014 mm supports close-tolerance hole requirements\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a DIN 1897 stub-length drill bit for use in standard drill chucks, collets, and screw machine toolholders accepting a straight-cylindrical shank.

Secure the shank fully in the chuck or collet before operation and verify runout before drilling. Do not exceed the recommended maximum drilling depth of 0.399 inches without retracting to clear chips. Always power down or lock out the machine before changing tooling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.1015 inches (Wire Size 38)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 130 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt\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\u003eOverall Length\u003c\/strong\u003e: 43.00 mm (approx. 1.693 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 14.00 mm (approx. 0.551 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.399 inches (10.13 mm)\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\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel, Web-Thinned\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\u003eDiameter Tolerance\u003c\/strong\u003e: +0.000 to -0.014 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Titanium Alloy\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: 659\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: 9006590025800\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51727254552882,"sku":"9006590025800","price":21.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6fba596b92b89874eb7b1e18755af446.jpg?v=1788675481","url":"https:\/\/voomisupply.com\/products\/guhring-9006590025800-cobalt-stub-drill-bit-0-1015-in","provider":"Voomi Supply","version":"1.0","type":"link"}
