It features a 6.50 mm (0.2559 inch) diameter, a 140-degree split point, and a nano-Si multi-layer coating that extends tool life in high-heat cutting conditions. The straight cylindrical shank measures 8 mm in diameter and seats securely in standard drill chucks and toolholders. With a 5xD flute-to-diameter ratio and web-thinned tip geometry, this drill is designed for self-centering entry without a pilot hole. It is installed and operated by machinists and toolroom technicians working on CNC machining centers, drill presses, and manual mills.\u003c\/p\u003e\u003cp\u003eThis drill is built for cutting steel and high-temperature alloys, making it suited for aerospace, automotive, and general metalworking applications. The coolant-through design channels cutting fluid directly to the tip, reducing heat buildup and chip packing when drilling at depth. It fits workflows where consistent hole quality in tough materials is required. The Series 8521 designation follows DIN 6535 and DIN 6537 L standards, making it a recognized geometry within shops that specify tooling to DIN specifications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in steel and high-temp alloys\u003c\/li\u003e\n\u003cli\u003e140-degree point angle with web-thinned tip for self-centering, reduced thrust force\u003c\/li\u003e\n\u003cli\u003enano-Si multi-layer coating for extended tool life and thermal protection\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports deep-hole drilling up to 43.25 mm (1.703 inches)\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting, regular spiral flute for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eConforms to DIN 6535 and DIN 6537 L standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in steel (material code P) and high-temperature alloys (material code S) per ISO material classification.

Ensure the machine spindle is fully stopped and locked out before mounting or removing the tool. Confirm the toolholder bore and collet are clean and within specified runout tolerances before seating the shank. When using the coolant-through feature, verify that coolant pressure and flow rate match the machine specification to prevent tip damage during operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 6.50 mm (0.2559 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 91.00 mm (3.5827 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 53.00 mm (2.0866 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 43.25 mm (1.703 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 8 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 36 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 140 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: Regular Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: nano-Si Multi-layer\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: m7\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, High-Temp Alloy\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: DIN 6535, DIN 6537 L\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 8521\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 pounds\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: 9085210065000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51743337382194,"sku":"9085210065000","price":274.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/204da00ca3732dde5c08d450c731edbe_6f4c742b-6d79-4890-9d09-9fcd91f07240.jpg?v=1788845828","url":"https:\/\/voomisupply.com\/products\/guhring-9085210065000-solid-carbide-jobber-drill-6-50-mm","provider":"Voomi Supply","version":"1.0","type":"link"}
