It features a 4.60 mm diameter (0.1811 inch) with a 140-degree split point and a TiAlN coating that extends tool life in ferrous and abrasive materials. The two-flute, right-hand spiral design clears chips efficiently at elevated feed rates. With a 74 mm overall length and a 36 mm flute length, this drill is suited for machinists, tool-and-die setters, and CNC operators working to close-tolerance requirements on production runs or maintenance operations.\u003c\/p\u003e\u003cp\u003eThis drill bit fits standard machining and drilling applications in metalworking environments including milling machines, drill presses, and CNC machining centers. The straight cylindrical shank with a 6 mm shank diameter seats cleanly in conventional drill chucks and collet holders. The 5xD flute-to-diameter ratio and R-thinned web geometry reduce entry force and improve hole entry accuracy. It is appropriate for production drilling of steel, cast iron, stainless, and similar materials where a high-performance solid carbide tool is specified.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard or abrasive workpiece materials\u003c\/li\u003e\n\u003cli\u003eTiAlN coating improves heat resistance and extends tool life at higher cutting speeds\u003c\/li\u003e\n\u003cli\u003e140-degree point angle reduces thrust force and promotes self-centering on entry\u003c\/li\u003e\n\u003cli\u003eR-thinned web geometry lowers cutting resistance and improves chip evacuation\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports internal coolant delivery for deep-hole or high-speed applications\u003c\/li\u003e\n\u003cli\u003eDIN specification designation ensures dimensional conformance to recognized tooling standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a high-performance solid carbide jobber drill for use in standard drill chucks and collet systems accepting a 6 mm straight cylindrical shank across a range of metalworking machine platforms.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator. Secure the shank fully within the chuck or collet and verify runout before beginning a cut. Confirm that the machine spindle speed and feed rate are appropriate for the workpiece material and drill diameter before engaging the cut. When using the coolant-through feature, ensure the coolant supply line is connected and pressurized before the tool enters the workpiece.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 4.60 mm (0.1811 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 74 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 36 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\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\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 5xD\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\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\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\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\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\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 4500146\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51739700363570,"sku":"4500146","price":122.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c5a470d1258ab7a501aadb93c1779e69_4223f854-641b-450a-aa85-47102656b680.jpg?v=1788818002","url":"https:\/\/voomisupply.com\/products\/accupro-4500146-carbide-jobber-drill-4-60mm-140-deg-tialn","provider":"Voomi Supply","version":"1.0","type":"link"}
