With a 0.2813 inch diameter (Letter size K), a 6.102 inch flute length, and an 8.858 inch overall length, this bit extends reach well beyond standard jobber-length tooling. The parabolic flute geometry promotes efficient chip evacuation, reducing heat buildup and deflection during extended cuts. A web-thinned, tapered web configuration lowers thrust force at the point, making entry cleaner in tough materials. Manufactured to DIN 1869 specification, this Series 618 bit suits demanding production and maintenance environments where precision and tool life matter.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for deep hole drilling in aluminum, titanium alloys, and steel. The 130-degree drill point angle is well-matched to the harder workpiece materials in this range. A straight-cylindrical shank at 9\/32 inch diameter seats securely in standard drill chucks and collet holders. The 15xD flute-to-diameter ratio and a maximum drilling depth of 5.681 inches make it appropriate for applications in aerospace, automotive, and general metalworking shops where standard drill lengths fall short. Right-hand cutting direction is conventional for standard spindle setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt tool material for heat resistance in steel and titanium alloy cutting\u003c\/li\u003e\n\u003cli\u003eParabolic flute design for improved chip evacuation in deep hole applications\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, tapered web reduces entry thrust and improves point stability\u003c\/li\u003e\n\u003cli\u003e130-degree drill point angle optimized for harder and mixed workpiece materials\u003c\/li\u003e\n\u003cli\u003eDIN 1869 specification ensures dimensional consistency and interchangeability\u003c\/li\u003e\n\u003cli\u003e15xD flute-to-diameter ratio with 5.681 inch maximum drilling depth\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a DIN 1869 Series 618 extra length drill bit compatible with standard drill chucks and collet holders accepting a 9\/32 inch straight-cylindrical shank.

Before mounting, verify the spindle and chuck are fully stopped and the machine is powered down or e-stopped. Seat the straight-cylindrical shank fully in the chuck or collet to the recommended grip depth to prevent pullout during deep hole cycles. Observe all applicable shop safety procedures and machine manufacturer guidelines when operating at extended reach depths.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.2813 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: K\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 8.858 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 6.102 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 5.681 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 9\/32 inch straight-cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 70 mm\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: Parabolic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 15xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, web-thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated\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: Aluminum, Titanium Alloy\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 618\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.000 to -0.022 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: DIN 1869\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: High Performance\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: 9006180071400\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51749947048242,"sku":"9006180071400","price":136.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7127cf6c7e2163c0cec3364e06224931.jpg?v=1788912481","url":"https:\/\/voomisupply.com\/products\/guhring-9006180071400-extra-length-cobalt-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
