It carries a diamond coating, which substantially reduces wear and heat buildup when cutting abrasive composite workpieces. The bit measures 8.00 mm in diameter with an overall length of 91.00 mm (3.5827 inches) and a flute length of 53.00 mm (2.0866 inches). The 140-degree point angle is suited to minimize delamination and fiber tear-out in composite stacks. This bit is installed by aerospace fabricators, composite technicians, and precision machinists working with CFRP panels, laminates, and structural composite assemblies.\u003c\/p\u003e\u003cp\u003eThe 4500205 is sized for CFRP drilling operations where tool life and hole-wall quality are critical. Its straight cylindrical shank accepts standard drill chucks and collet holders sized for 8.00 mm shanks. The regular spiral, two-flute design promotes chip evacuation from abrasive composite material. This bit is a specialized-grade tool intended for production or maintenance drilling of carbon fiber components in aerospace, motorsport, and industrial composite fabrication environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDiamond coating extends tool life in abrasive CFRP and composite materials\u003c\/li\u003e\n\u003cli\u003e140-degree proprietary point angle reduces delamination and fiber tear-out on entry and exit\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction provides rigidity for tight-tolerance hole sizing\u003c\/li\u003e\n\u003cli\u003eTwo-flute regular spiral geometry promotes chip clearance during composite drilling\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical 8.00 mm shank fits standard chucks and collet systems\u003c\/li\u003e\n\u003cli\u003e5xD flute-to-diameter ratio supports deeper hole drilling without regrind\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a specialized OEM-style jobber drill for CFRP and composite material applications; fits any drill press, CNC machining center, or handheld drill with an 8.00 mm straight-shank collet or chuck.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis drill bit is intended for use by machinists and composite fabrication technicians operating drill presses, milling machines, or CNC equipment. Ensure the spindle and workpiece are fully secured before engaging the tool. Coolant-through is not supported on this bit; dry cutting or external air blast is the typical approach for CFRP to avoid moisture contamination of the laminate. Inspect the cutting edges and diamond coating for wear regularly, as CFRP is highly abrasive and can degrade the cutting edge faster than metal substrates.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 8.00 mm (0.3150 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\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Diamond\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\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 8.00 mm\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: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: CFRP Materials\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 Grade\u003c\/strong\u003e: Specialized\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Designation\u003c\/strong\u003e: DIN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.17 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: ACCUPRO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 4500205\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51744038289714,"sku":"4500205","price":210.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7cc8a34ad23298862eba16e0bddc6397.jpg?v=1788853355","url":"https:\/\/voomisupply.com\/products\/accupro-4500205-solid-carbide-jobber-drill-8mm-140-deg","provider":"Voomi Supply","version":"1.0","type":"link"}
