It measures 6.50 mm (0.2559 inches) in diameter and features a 140-degree split-point geometry that reduces walking and lowers thrust at entry. The multilayer TiAlN coating resists heat and wear, extending tool life in demanding production environments. At 91.00 mm overall length with a 53.00 mm flute length, the 4150690 fits standard jobber-drill setups on CNC machining centers, drill presses, and hand-held power tools. Licensed machinists and tooling technicians are the primary users.\u003c\/p\u003e\u003cp\u003eThis drill is suited for cutting steel, stainless steel, cast iron, aluminum, and other non-ferrous materials in both light manufacturing and production-floor environments. The right-hand spiral flute promotes efficient chip evacuation, which is especially important when drilling deeper holes in tight-tolerance workpieces. The whistle notch shank provides positive retention in standard drill chucks and collet holders, reducing slippage under torque. No through-coolant is required, making the 4150690 compatible with dry or mist-lubricated setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003e140-degree point angle reduces entry walking and lowers axial thrust\u003c\/li\u003e\n\u003cli\u003eMultilayer TiAlN coating extends tool life in high-temperature cutting conditions\u003c\/li\u003e\n\u003cli\u003eRight-hand regular spiral flute for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eWhistle notch shank provides positive chuck retention and prevents rotation slip\u003c\/li\u003e\n\u003cli\u003eNo through-coolant required — compatible with dry or mist-lubrication setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style solid carbide jobber drill for use in standard drill chucks and collet holders accepting a 6.50 mm shank across CNC machining centers, drill presses, and handheld drilling equipment.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes should be performed by qualified machinists or tooling technicians with the spindle fully stopped and machine power locked out. Verify chuck or collet runout before seating the drill to avoid premature edge chipping. Solid carbide tooling is brittle — avoid side loading or interrupted cuts beyond the drill's rated application range. Follow applicable shop safety standards and machine manufacturer guidelines for speed and feed selection.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 6.50 mm (0.2559 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\u003eOverall Length\u003c\/strong\u003e: 91.00 mm (3.58 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 53.00 mm (2.09 inches)\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\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: Whistle Notch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Aluminum, Non-Ferrous\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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: 0.7 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: KENNAMETAL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 4150690\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51732781170994,"sku":"4150690","price":123.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b20821d7be70a5a4c765d3cd5c97400d.jpg?v=1788746734","url":"https:\/\/voomisupply.com\/products\/kennametal-4150690-solid-carbide-jobber-drill-6-50-mm","provider":"Voomi Supply","version":"1.0","type":"link"}
