It features a 140-degree split point with proprietary UR-thinning at the web, which reduces thrust and improves center-starting without a pilot hole. The TiAlN coating provides thermal resistance and extended tool life when drilling at elevated cutting speeds. At 4.134 inches overall length with a 2.244-inch flute, this is a general-purpose jobber geometry suited for production environments. Machinists, tool and die makers, and CNC operators working in job shops or manufacturing facilities are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is engineered for hardened materials, including tool steels and other high-hardness workpieces where high-speed steel tooling loses edge integrity. The slow-spiral flute design controls chip evacuation in tough materials without generating excessive heat in the cutting zone. With a straight cylindrical shank at 10 mm diameter, it seats in standard drill chucks and collet holders on machining centers, drill presses, and CNC lathes. The DIN specification designation confirms it meets recognized European and international dimensional standards for interchangeable tooling.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in hardened workpieces\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating extends tool life at high cutting temperatures\u003c\/li\u003e\n  \u003cli\u003e140-degree point angle reduces exit burr and improves point stability on entry\u003c\/li\u003e\n  \u003cli\u003eUR-thinned web lowers axial thrust and aids self-centering\u003c\/li\u003e\n  \u003cli\u003eSlow-spiral flute geometry optimized for chip control in tough, hard materials\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank fits standard collets and drill chucks without adapters\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a DIN-standard straight-shank jobber drill for use in machining centers, CNC drill presses, and manual drill presses equipped with collet or chuck toolholding accepting a 10 mm shank diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use should be performed by qualified machinists or CNC operators familiar with cutting tool setup and speeds-and-feeds selection for carbide tooling. Ensure the spindle is fully stopped and the machine is in a safe state before inserting or removing the drill from the toolholder. Carbide is brittle — avoid lateral loading, interrupted cuts without proper setup, and contact with hardened surfaces outside the intended cutting application. Confirm runout at the shank is within tolerance before starting a production run, as excessive runout accelerates edge chipping on solid carbide tools.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 8.80 mm (0.3465 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 105.00 mm (4.134 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 57.00 mm (2.244 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: Proprietary (UR-Thinned Web)\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: TiAlN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Slow 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\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 10 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 4xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Hardened Materials\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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: Specialized\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.17 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: ACCUPRO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 4500054\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51737013748018,"sku":"4500054","price":131.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/83a2e8e9529c3f993f224abdb5d92e9d.jpg?v=1788783167","url":"https:\/\/voomisupply.com\/products\/accupro-4500054-solid-carbide-jobber-drill-8-80-mm-tialn","provider":"Voomi Supply","version":"1.0","type":"link"}
