Built to Series 8521 standards, it features a 7.00 mm cutting diameter, a 140-degree HF point angle, and a web-thinned tip geometry that promotes self-centering entry without a center punch. Coolant-through capability delivers cutting fluid directly to the cutting edge, extending tool life and improving chip evacuation in deep-hole applications. The 2-flute spiral design and right-hand cutting direction suit most CNC machining centers and drill presses configured for conventional rotation.\u003c\/p\u003e\u003cp\u003eThis drill is rated for titanium alloy as its primary workpiece material, placing it in demanding aerospace, medical device, and precision manufacturing environments. Its 5xD flute-to-diameter ratio and a maximum drilling depth of 42.50 mm make it well suited for through-hole and blind-hole operations where tool rigidity and thermal management are critical. The straight-cylindrical shank, ground to an 8.00 mm diameter with an m7 tolerance, seats securely in standard collet chucks or hydraulic toolholders. Machinists and CNC operators in job shops and production facilities are the primary users of this drill.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and heat resistance in hard and exotic 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 channels cutting fluid to the tip for thermal control and chip removal\u003c\/li\u003e\n\u003cli\u003e5xD flute length supports drilling depths up to 42.50 mm\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank ground to m7 tolerance for precise chuck or collet fit\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 as an OEM-style replacement or direct-use drill conforming to DIN 6535 and DIN 6537 L specifications; compatible with any spindle or toolholder accepting an 8.00 mm straight-cylindrical shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by qualified machinists or CNC operators familiar with carbide tooling. Ensure the machine spindle and toolholder are clean and free of runout before seating the shank, as carbide is brittle and sensitive to side-loading. Verify that the coolant-through system is active before initiating the cut to prevent thermal shock to the cutting edge. Do not use this drill in hand-held or low-speed drilling applications where RPM and feed rate cannot be precisely controlled.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 7.00 mm (0.2756 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 91.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 53.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 42.50 mm (1.673 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 8.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 36.00 mm\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\u003eDiameter Tolerance\u003c\/strong\u003e: m7\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Titanium Alloy\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: High Performance\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: 0.043 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: 9085210070000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51734050144562,"sku":"9085210070000","price":304.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/204da00ca3732dde5c08d450c731edbe_eb1fa769-b6bc-44ae-89e3-8a0b74237de8.jpg?v=1788760671","url":"https:\/\/voomisupply.com\/products\/guhring-9085210070000-carbide-jobber-drill-7mm-140-deg","provider":"Voomi Supply","version":"1.0","type":"link"}
