The bit measures 8.10 mm (0.3189 inches) in diameter with a 140-degree proprietary point angle and a TiAlN (titanium aluminum nitride) coating that extends tool life under high heat and abrasive conditions. A slow spiral, two-flute design controls chip evacuation while maintaining rigidity in demanding applications. Overall length is 98.00 mm (3.8583 inches) with a 50.00 mm (1.9685 inches) flute length. The straight cylindrical shank is 10 mm in diameter and seats in standard chucks or toolholders. This is a right-hand cutting drill intended for CNC machining centers, drill presses, and manual machines running at appropriate surface footage for carbide tooling.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for production and job-shop environments where hardened steels, tool steels, and similarly abrasive workpiece materials are common. The 4xD flute-to-diameter ratio makes it a standard jobber-length option for through-hole and blind-hole operations in hardened material applications. The UR-thinned web reduces entry thrust forces, which is a practical advantage when drilling fully hardened workpieces. Machinists, toolroom technicians, and CNC operators will find it a direct fit where carbide-grade tooling is required per shop process specifications. The DIN specification designation confirms dimensional conformance to international standards.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction resists wear and maintains edge integrity in hardened workpiece materials\u003c\/li\u003e\n\u003cli\u003eTiAlN coating provides thermal and oxidation resistance for extended tool life at elevated cutting temperatures\u003c\/li\u003e\n\u003cli\u003e140-degree proprietary point angle with UR-thinned web reduces thrust and improves center location on hard stock\u003c\/li\u003e\n\u003cli\u003eSlow spiral flute design maintains rigidity and controls chip flow in short-chipping hard materials\u003c\/li\u003e\n\u003cli\u003eTwo-flute geometry with 4xD flute-to-diameter ratio suits standard jobber-length drilling operations\u003c\/li\u003e\n\u003cli\u003eDIN-compliant dimensions ensure compatibility with standard toolholders and chuck systems\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 10 mm straight cylindrical shank. Rated for hardened materials per the manufacturer specification designation.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCarbide drill bits require secure, concentric clamping in a collet chuck or hydraulic toolholder to prevent runout-induced breakage. Power down and lock out the machine spindle before loading or removing tooling. Use cutting speeds and feed rates appropriate for solid carbide in hardened stock — running carbide at high-speed-steel parameters will cause premature failure. This drill does not support coolant-through delivery; apply flood or mist coolant externally at the cutting zone when possible.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 8.10 mm (0.3189 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 98.00 mm (3.8583 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 50.00 mm (1.9685 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 10 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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: UR-Thinned\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: Slow Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 4xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\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\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: 4500019\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51749331042610,"sku":"4500019","price":131.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/54d1016994f3f69943f98488155cec90.jpg?v=1788904610","url":"https:\/\/voomisupply.com\/products\/accupro-4500019-solid-carbide-jobber-drill-8-10mm-tialn","provider":"Voomi Supply","version":"1.0","type":"link"}
