It features a 140-degree split point geometry that improves self-centering and reduces thrust force compared to standard 118-degree points. The multilayer TiAlN coating adds heat resistance and extends tool life when drilling abrasive or hard materials. At 1\/8 inch (0.1250 inch) diameter, this bit is suited for precision hole-making in tight-tolerance applications. A right-hand cutting direction and regular spiral flute geometry promote efficient chip evacuation. Licensed tradespeople and machinists in metal fabrication, maintenance, and production settings are the primary users of this tool.\u003c\/p\u003e\n\u003cp\u003eThis jobber drill is intended for use on steel, stainless steel, cast iron, aluminum, and non-ferrous materials. The 0.1250 inch diameter and 1.1024 inch flute length make it well suited for drilling shallow to moderate-depth holes in components where hole quality and dimensional accuracy matter. The whistle notch shank provides a positive retention point in drill chucks equipped to accept it, reducing the risk of shank slip under torque. This bit fits typical jobber-drill applications in CNC machining centers, drill presses, and handheld power tools used in industrial and maintenance trades.\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\u003eMultilayer TiAlN coating improves heat resistance and extends cutting tool life\u003c\/li\u003e\n  \u003cli\u003e140-degree point angle promotes self-centering and reduces walking on entry\u003c\/li\u003e\n  \u003cli\u003eWhistle notch shank provides positive chuck retention and resists rotational slip\u003c\/li\u003e\n  \u003cli\u003eRight-hand regular spiral flute geometry supports efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through design simplifies setup on standard drill presses and handheld equipment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a high-performance replacement jobber drill for applications in steel, stainless steel, cast iron, aluminum, and non-ferrous materials where a 1\/8 inch diameter carbide bit with a whistle notch shank is specified.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use of this tool should be performed by a qualified machinist or trade professional familiar with carbide tooling. Before mounting, ensure the drill press or machine spindle is fully de-energized and locked out per applicable safety procedures. Verify the chuck is rated for the whistle notch shank style and that runout is within acceptable limits before drilling, as excessive runout can chip carbide cutting edges. Carbide tooling is brittle and should not be subjected to side loading or used to ream existing holes.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Inch)\u003c\/strong\u003e: 1\/8 inch (0.1250 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\u003eDrill Bit Material\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\u003eFlute Length\u003c\/strong\u003e: 1.1024 inches (28.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5984 inches (66.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Whistle Notch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Aluminum, Non-Ferrous\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: High Performance\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\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: 4150635\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51755040047410,"sku":"4150635","price":117.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3b8ad27a63d618c048e6d1de5390eba1.jpg?v=1788950706","url":"https:\/\/voomisupply.com\/products\/kennametal-4150635-jobber-drill-1-8-inch-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
