Part of the Guhring Series 8521, it carries a nano-SI coating and features a 140-degree HF drill point optimized for self-centering entry without a center punch. The straight-cylindrical shank measures 8 mm in diameter with an overall length of 91 mm (approximately 3.58 inches) and a flute length of 53 mm (approximately 2.09 inches). With coolant-through capability and a web-thinned tip, it maintains cutting efficiency at depth and extends tool life in abrasive alloy applications. Licensed machinists and toolroom technicians typically specify this bit for precision production and job shop work.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is designed primarily for titanium alloy workpieces (material code P; S) and similar high-strength, work-hardening materials encountered in aerospace, medical device, and industrial manufacturing environments. The right-hand spiral flute geometry with a regular spiral type evacuates chips effectively in deep-hole applications, with a maximum drilling depth of 41 mm (approximately 1.61 inches). The 5xD flute-to-diameter ratio supports stable performance across CNC machining centers and conventional drill presses where tight diameter tolerances are required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction with nano-SI coating for wear resistance in titanium and hard alloys\u003c\/li\u003e\n  \u003cli\u003e140-degree HF point angle with web thinning for self-centering entry and reduced thrust force\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design delivers cutting fluid directly to the tip for extended tool life at depth\u003c\/li\u003e\n  \u003cli\u003e8 mm straight-cylindrical shank (DIN 6535) with m7 diameter tolerance for precise chuck fit\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 6537 L jobber length standard ensuring dimensional consistency\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, 2-flute spiral geometry for efficient chip evacuation in deep-hole drilling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style precision drill bit conforming to DIN 6537 L and DIN 6535 standards, suitable for use in standard 8 mm collets, chucks, and toolholders on CNC machining centers and conventional drill presses.

Always verify that the machine spindle and toolholder are clean and free of runout before seating the shank, as carbide is brittle and susceptible to fracture under lateral load. Ensure coolant-through supply is active before drilling titanium or hard alloys to prevent heat buildup and premature edge failure. Do not use this bit for hand drilling or in underpowered machines that cannot maintain consistent feed and speed rates.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 8 mm (0.3150 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 91 mm (approximately 3.58 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 53 mm (approximately 2.09 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 41 mm (approximately 1.61 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 (approximately 1.42 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: HF (self-centering)\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: Spiral, Regular\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\u003eDrill Bit Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: nano-SI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: High Performance\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Titanium Alloy\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\u003eDiameter Tolerance\u003c\/strong\u003e: m7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 8521\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\u003eWeight\u003c\/strong\u003e: 0.048 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: 9085210080000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51737695682866,"sku":"9085210080000","price":318.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/204da00ca3732dde5c08d450c731edbe_26750197-6b5d-4ad4-92f3-27fd05031cf1.jpg?v=1788792438","url":"https:\/\/voomisupply.com\/products\/guhring-9085210080000-solid-carbide-jobber-drill-bit-8-mm","provider":"Voomi Supply","version":"1.0","type":"link"}
