It measures 18 mm (0.7087 inches) in diameter with an overall length of 143 mm (5.63 inches) and a flute length of 93 mm (3.66 inches). The 140-degree split point and R-thinned web reduce entry force and improve centering on hard surfaces. A TiAlN coating adds heat resistance and extends tool life under aggressive cutting conditions. This drill is intended for use by machinists, tool-and-die professionals, and precision metalworking shops running CNC or manual drilling operations.\u003c\/p\u003e\u003cp\u003eThis drill bit is optimized for cutting stainless steel and other difficult-to-machine ferrous and non-ferrous alloys. The 5xD flute-to-diameter ratio supports deeper hole applications within the jobber range. Coolant-through capability allows internal delivery of cutting fluid directly to the tip, making it well suited for production environments where heat buildup and chip evacuation are primary concerns. The straight cylindrical shank seats into standard drill chucks and collet holders without modification.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard materials\u003c\/li\u003e\n\u003cli\u003eTiAlN coating for elevated heat resistance and extended tool life\u003c\/li\u003e\n\u003cli\u003e140-degree point angle with R-thinned web for improved centering and reduced thrust\u003c\/li\u003e\n\u003cli\u003eCoolant-through design for internal cutting fluid delivery\u003c\/li\u003e\n\u003cli\u003eRight-hand, regular spiral flute geometry for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank compatible with standard chucks and collet systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a high-performance OEM-style jobber drill for use in CNC machining centers, drill presses, and manual lathes equipped with standard straight-shank toolholders.

Ensure the machine spindle and toolholder are clean and within tolerance before seating the shank. Carbide is brittle — avoid side loading, interrupted cuts without proper support, or over-tightening chuck jaws that can crack the shank. When using coolant-through capability, confirm the machine spindle supplies adequate pressure and that coolant lines are clear before beginning the cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 18 mm (0.7087 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 143 mm (5.63 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 93 mm (3.66 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\u003c\/strong\u003e: TiAlN\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\u003eShank Diameter\u003c\/strong\u003e: 18 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: R-Thinned\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\u003eDrill Bit Grade\u003c\/strong\u003e: High Performance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Designation\u003c\/strong\u003e: DIN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241634\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: 4500240\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51748812259634,"sku":"4500240","price":533.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a3a6c12fce45d00f6b8248cfae83a451.jpg?v=1788898823","url":"https:\/\/voomisupply.com\/products\/accupro-4500240-solid-carbide-jobber-drill-18-mm-tialn","provider":"Voomi Supply","version":"1.0","type":"link"}
