It features a 140-degree standard point angle and a multilayer TiAlN coating that extends tool life under demanding cutting conditions. The overall length is 6.0236 inches, with a right-hand spiral flute configuration and a straight cylindrical shank measuring 0.2500 inch in diameter. This bit is coolant-through capable, making it well-suited for production drilling environments where heat management is critical. Machinists and tool-room professionals working in job shops, manufacturing cells, and maintenance operations are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis jobber drill is built to DIN 6537K specification, placing it in the high-performance solid carbide category for precision hole-making. It is appropriate for use in CNC machining centers, drill presses, and manual knee mills where a straight-shank toolholder or drill chuck is used. The 5xD flute-by-diameter ratio and a maximum drilling depth of 3.0315 inches make it suitable for moderate-depth through-holes and blind holes in ferrous and non-ferrous workpieces. The tapered web configuration aids chip evacuation and reduces thrust force at the cutting edge.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction provides rigidity and wear resistance beyond high-speed steel alternatives\u003c\/li\u003e\n  \u003cli\u003eMultilayer TiAlN coating improves heat and oxidation resistance for extended tool life in steel and stainless steel\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design channels coolant directly to the cutting zone, reducing heat buildup at depth\u003c\/li\u003e\n  \u003cli\u003e140-degree standard point angle reduces walking and improves centering on entry\u003c\/li\u003e\n  \u003cli\u003eTapered web configuration promotes efficient chip evacuation and lower cutting thrust\u003c\/li\u003e\n  \u003cli\u003eDIN 6537K specification ensures dimensional consistency for repeatable hole tolerances\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers and drill presses with straight-shank toolholders or drill chucks accommodating a 0.2500 inch shank diameter.

Secure the straight shank in a properly sized collet chuck or drill chuck and verify runout before beginning a cut, as carbide is more brittle than high-speed steel and sensitive to lateral loading. Engage coolant flow before contact with the workpiece when using the through-coolant feature. Avoid interrupting the cut with excessive feed variation, which can chip the cutting edge.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.7500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6.0236 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3.9764 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.9685 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\u003eDrill Point Length\u003c\/strong\u003e: 0.1304 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 3.0315 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: -0.0008 to 0.0000 inches\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\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\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: Multilayer TiAlN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: DIN 6537K\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Aluminum and Non-Ferrous\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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: KENNAMETAL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 4149411\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51741271195954,"sku":"4149411","price":808.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6047723244c39e297ff48cf30f8b8e5b_3f27fe0f-8254-4a8b-9580-1fa2bf7f4740.jpg?v=1788830440","url":"https:\/\/voomisupply.com\/products\/kennametal-4149411-solid-carbide-jobber-drill-bit-3-4-inches","provider":"Voomi Supply","version":"1.0","type":"link"}
