Built to DIN specification, it features a 140-degree split point with R-thinning for reduced thrust and improved self-centering on entry. The TiAlN coating provides thermal resistance and extended tool life at elevated cutting speeds. At 7.80 mm in diameter with a 3.5827-inch overall length and a 2.0866-inch flute length, this drill is suited for applications where dimensional accuracy and tool longevity are critical. Coolant-through capability supports chip evacuation and heat management during deep-hole operations. It is installed by machinists, tool-and-die makers, and maintenance technicians working in production or job-shop environments.\u003c\/p\u003e\u003cp\u003eThis drill bit is optimized for cutting stainless steel and other hard or work-hardening materials where carbide substrate and TiAlN coating outperform high-speed steel alternatives. The 5xD flute-to-diameter ratio provides a longer flute for deeper cuts within the jobber-length class. The right-hand, regular spiral flute geometry promotes consistent chip flow in CNC machining centers, drill presses, and manual lathes with drill chucks. The straight cylindrical shank with an 8 mm shank diameter fits standard ER collets and drill chucks without adapter sleeves.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide substrate for rigidity and wear resistance in hard materials\u003c\/li\u003e\n\u003cli\u003eTiAlN coating for high-temperature performance and extended tool life\u003c\/li\u003e\n\u003cli\u003e140-degree proprietary point angle with R-thinning reduces entry thrust and improves centering\u003c\/li\u003e\n\u003cli\u003eCoolant-through design for effective chip evacuation and heat control in deep holes\u003c\/li\u003e\n\u003cli\u003eRight-hand, regular spiral flute with 5xD ratio for consistent chip flow\u003c\/li\u003e\n\u003cli\u003eDIN specification compliance for dimensional reliability\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a jobber-length carbide drill for use in CNC machining centers, drill presses, and similar equipment accepting a straight cylindrical 8 mm shank.

Ensure the machine spindle is fully stopped and locked out before mounting or removing the drill. Verify coolant-through supply is connected and flowing before drilling to protect the cutting edge and promote chip clearing. Follow machine manufacturer feed and speed recommendations for carbide tooling in the target workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 7.80 mm (0.3071 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\u003eShank Diameter\u003c\/strong\u003e: 8 mm straight cylindrical\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: Proprietary with R-thinned web\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: TiAlN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Regular Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Designation\u003c\/strong\u003e: DIN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: High Performance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.17 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241634\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ACCUPRO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 4500245\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51733776564530,"sku":"4500245","price":142.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7c6818bac8bd8f163442994c290dc1dd.jpg?v=1788759166","url":"https:\/\/voomisupply.com\/products\/accupro-4500245-jobber-drill-7-80mm-solid-carbide-tialn","provider":"Voomi Supply","version":"1.0","type":"link"}
