It measures 9.20 mm in diameter with a 140-degree split point and a TiAlN coating that extends tool life by reducing heat and wear at the cutting edge. Overall length is 4.06 inches with a 2.40-inch flute length. The two-flute, regular spiral design promotes efficient chip evacuation, and the R-thinned web reduces thrust load at entry. This drill is suited for machinists, tool and die technicians, and production drilling environments where precision and tool longevity are critical.\u003c\/p\u003e\u003cp\u003eThe 4500281 is rated for primary use in stainless steel, making it appropriate for shops machining 300 and 400 series alloys, duplex stainless, and similarly tough ferrous materials. The coolant-through design allows internal coolant delivery directly to the cutting zone, which is essential when drilling deep holes or running at elevated feeds and speeds in heat-resistant alloys. The straight cylindrical shank fits standard drill chucks and collet systems without modification. This is a right-hand cutting tool intended for conventional CNC machining centers, drill presses, and manual lathes with live tooling.\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 reduces thermal buildup and extends tool life in stainless steel\u003c\/li\u003e\n\u003cli\u003e140-degree proprietary point angle for precise entry and reduced walking\u003c\/li\u003e\n\u003cli\u003eCoolant-through design delivers fluid directly to the cutting edge\u003c\/li\u003e\n\u003cli\u003eR-thinned web lowers thrust requirements and improves centering\u003c\/li\u003e\n\u003cli\u003eRegular spiral flute geometry promotes consistent chip evacuation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a high-performance replacement jobber drill for applications requiring a 9.20 mm diameter solid carbide bit with a straight cylindrical shank, conforming to DIN specification standards.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and operation should be performed by qualified machinists familiar with carbide tooling requirements. Secure the straight shank fully in a drill chuck or collet before operation and verify runout is within acceptable limits for the application. Enable coolant flow before engaging the cut when using the through-coolant feature. Carbide tooling is brittle — avoid side loading, interrupted cuts without appropriate parameters, or dropping the tool on hard surfaces.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 9.20 mm (0.3622 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 103.00 mm (4.06 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 61.00 mm (2.40 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\u003ePoint Type\u003c\/strong\u003e: Proprietary\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: R-Thinned\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\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\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: 4500281\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51749248794930,"sku":"4500281","price":161.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e6c771c149a90e3cd3bc1f4341d6d83b.jpg?v=1788903579","url":"https:\/\/voomisupply.com\/products\/accupro-4500281-solid-carbide-jobber-drill-9-20-mm","provider":"Voomi Supply","version":"1.0","type":"link"}
