Built from solid carbide with a multilayer TiAlN coating at the tip, this bit delivers high wear resistance and thermal stability during high-speed drilling operations. The 140-degree point angle provides aggressive cutting action and reduces thrust load. With an overall length of 66.00 mm (2.598 inches) and a 4.40 mm cutting diameter, this bit is sized for close-tolerance work in tight-reach applications. It is suited for machinists, toolroom technicians, and CNC operators working with ferrous and non-ferrous materials.\u003c\/p\u003e\u003cp\u003eThis drill bit is designed for use in screw machine operations, CNC machining centers, and drill press applications where short, rigid tooling reduces deflection and improves positional accuracy. The stub-length design limits overhang and increases rigidity compared to standard jobber-length bits. The straight cylindrical shank diameter of 6.00 mm (0.236 inches) accepts standard collet chucks and tool holders. It is commonly used in production environments where repeatable hole quality and dimensional consistency are required across high-cycle operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for superior rigidity and wear resistance versus high-speed steel alternatives\u003c\/li\u003e\n\u003cli\u003eTiAlN tip coating provides thermal and oxidation resistance during high-speed cutting\u003c\/li\u003e\n\u003cli\u003e140-degree point angle reduces drill walk and minimizes thrust force on entry\u003c\/li\u003e\n\u003cli\u003eStub-length (screw machine length) body limits deflection and improves hole straightness\u003c\/li\u003e\n\u003cli\u003e2-flute regular spiral design with tapered web for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank compatible with standard collet and drill chuck toolholders\u003c\/li\u003e\n\u003cli\u003eMeets DIN 6537K specification for consistent dimensional tolerancing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and production tooling option within the KENNAMETAL Series B041A-CPG stub-length carbide drill family, covering the 3.50 mm to 5.00 mm diameter range per DIN 6537K.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis drill bit should be installed by a qualified machinist or CNC operator using the appropriate collet or chuck rated for the 6.00 mm shank diameter. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before seating the shank. Do not exceed the maximum recommended drilling depth of 17.00 mm per the 3xD flute-to-diameter ratio. Verify spindle speed and feed rate against material hardness recommendations before engaging the cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 4.40 mm (0.1732 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 66.00 mm (2.598 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 24.00 mm (0.945 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6.00 mm (0.236 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 36.00 mm (1.417 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 17.00 mm (0.669 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.73 mm (0.029 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\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\u003eFlute-to-Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN (Tip)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Stub (Screw Machine Length)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0005 to 0.0000 inches (-0.012 to 0.000 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: DIN 6537K\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: B041A-CPG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 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: KENNAMETAL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 4150201\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51728391700786,"sku":"4150201","price":83.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/315d98dc3a5352504d1b99327eaec198.jpg?v=1788690835","url":"https:\/\/voomisupply.com\/products\/kennametal-4150201-screw-machine-drill-bit-4-40mm-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
