Sized at 25\/64 inch (0.3906 inch decimal), it features a 140-degree point angle that reduces thrust and improves centering on entry. The multilayer TiAlN coating increases surface hardness and thermal resistance, extending tool life in high-speed applications. A right-hand spiral flute geometry promotes efficient chip evacuation. This drill is installed and operated by machinists, tool-and-die technicians, and maintenance mechanics running CNC machining centers, drill presses, or manual machines.\u003c\/p\u003e\n\u003cp\u003eThis jobber drill is suited for drilling steel, stainless steel, cast iron, aluminum, and other non-ferrous materials in both production and job-shop settings. The whistle notch shank provides positive retention in compatible tool holders and chucks, reducing pullout risk under high feed rates. With a flute length of approximately 2.40 inches and an overall length of approximately 4.06 inches, it fits standard jobber-length drill chuck setups on vertical machining centers and radial arm drill presses. It is a solid choice for through-hole and blind-hole operations where dimensional accuracy and tool life are priorities.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard and abrasive workpiece materials\u003c\/li\u003e\n  \u003cli\u003e140-degree point angle reduces entry thrust and improves self-centering on flat and curved surfaces\u003c\/li\u003e\n  \u003cli\u003eMultilayer TiAlN coating provides high-temperature resistance and extended cutting edge life\u003c\/li\u003e\n  \u003cli\u003eRight-hand regular spiral flute promotes smooth chip flow and reduces chip packing\u003c\/li\u003e\n  \u003cli\u003eWhistle notch shank ensures positive retention and minimizes shank slippage in drill holders\u003c\/li\u003e\n  \u003cli\u003eHigh-performance grade rated for steel, stainless steel, cast iron, aluminum, and non-ferrous materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a high-performance OEM-style solid carbide jobber drill for use in standard whistle notch tool holders and chucks accepting a 25\/64 inch shank diameter across CNC and manual drilling equipment.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and operation should be performed by qualified machinists or maintenance technicians familiar with cutting tool safety. Ensure the machine spindle is fully stopped and all energy is locked out before changing tooling. Verify the whistle notch shank is fully seated and the retention setscrew or chuck jaws are properly engaged before starting the spindle. Do not exceed the recommended surface footage and feed rate parameters for the workpiece material being drilled, and use appropriate personal protective equipment including eye and face protection.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 25\/64 inch (0.3906 inch)\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: 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\u003eFlute Length\u003c\/strong\u003e: 2.40 inches (61.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.06 inches (103.00 mm)\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\u003eWeight\u003c\/strong\u003e: 0.7 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 4150737\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51730225266994,"sku":"4150737","price":169.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dbc5136f61c0d0525fc7c0d0ed3c61de.jpg?v=1788713642","url":"https:\/\/voomisupply.com\/products\/kennametal-4150737-solid-carbide-jobber-drill-25-64-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
