Built to DIN 1869 standards, this Series 502 bit features a parabolic flute geometry and a web-thinned, tapered web configuration that promotes efficient chip evacuation and reduces thrust at entry. The 0.2756 inch diameter corresponds to the 7.00 mm metric designation, and the bit runs uncoated in a right-hand cutting direction. Licensed machinists, toolroom technicians, and production floor operators working on aluminum and similar materials will recognize this as a purpose-built deep-hole tool with a 15xD flute-to-diameter ratio.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is primarily applied in deep hole drilling scenarios where standard-length bits cannot reach the required depth. The parabolic flute profile is especially well-suited to aluminum, plastics, and non-ferrous workpiece materials as identified by material codes K, N, and P. With a flute length of 6.102 inches and a maximum drilling depth of 5.689 inches, it is appropriate for CNC machining centers, drill presses, and manual machine tools where extended reach and chip clearance are critical. The straight-cylindrical shank with a 0.2756 inch shank diameter allows direct chuck mounting without additional adapters in standard toolholding setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eParabolic flute geometry with web thinning for improved chip evacuation in deep holes\u003c\/li\u003e\n  \u003cli\u003eMeets DIN 1869 standard for extra length twist drills\u003c\/li\u003e\n  \u003cli\u003e130 degree drill point angle with standard point type for positive entry\u003c\/li\u003e\n  \u003cli\u003eUncoated high-speed steel construction for use across a range of cutting fluids and dry conditions\u003c\/li\u003e\n  \u003cli\u003e15xD flute-to-diameter ratio supports drilling depths up to 5.689 inches\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction with two-flute configuration for consistent chip load\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a DIN 1869 Series 502 extra length drill bit for deep hole drilling operations in aluminum and non-ferrous workpiece materials.

Ensure the workpiece is securely fixtured and the spindle is at a full stop before loading or removing the bit. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain hole quality. Inspect the cutting edges and web area for wear before each use, particularly when running extended drilling cycles.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.2756 inches (7.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 225.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 6.102 inches (155.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 5.689 inches (144.50 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2756 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 70.00 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\u003eWeb Configuration\u003c\/strong\u003e: Tapered, 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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Aluminum (Material Codes K, N, P)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 15xD\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 1869\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 502\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: 9005020070000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51731010552114,"sku":"9005020070000","price":87.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f81d50d87f16177cf50d05488a54babf.jpg?v=1788725823","url":"https:\/\/voomisupply.com\/products\/guhring-9005020070000-extra-length-drill-bit-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
