Built from solid carbide, this bit delivers the rigidity and wear resistance required for drilling in hardened materials, composites, and tight-tolerance bores. It measures 6.35 mm in diameter with an overall length of 79 mm and a flute length of 34 mm. The straight cylindrical shank provides consistent chuck engagement. This drill is intended for use by machinists and CNC operators working in production or toolroom environments where accuracy and tool life are critical.\u003c\/p\u003e\u003cp\u003eThe 4150230 is suited for use in CNC machining centers, drill presses, and precision manual machines where micro-diameter drilling is required. The right-hand cutting direction makes it compatible with standard spindle rotation. Its solid carbide construction handles interrupted cuts and abrasive materials better than high-speed steel alternatives. Typical applications include component manufacturing in aerospace, automotive, and electronics sectors where tight hole tolerances are required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for high rigidity and extended tool life in abrasive materials\u003c\/li\u003e\n\u003cli\u003e6.35 mm drill diameter for precision micro-bore applications\u003c\/li\u003e\n\u003cli\u003e79 mm overall length with a 34 mm flute length for controlled chip evacuation\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank for consistent holding in standard drill chucks and collets\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction for use with standard spindle rotation\u003c\/li\u003e\n\u003cli\u003ePart of the B041A series for consistent geometry and interchangeability\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard tooling option for machines accepting a 6.35 mm straight cylindrical shank micro drill bit in right-hand cutting configurations.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and locked out before changing tooling. Secure the straight cylindrical shank firmly in a compatible collet or drill chuck to the appropriate clamping specification for your tool-holding system. Verify spindle direction is set to right-hand rotation before beginning the cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 6.35 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 79 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 34 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\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\u003eSeries\u003c\/strong\u003e: B041A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241600\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: 4150230\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51743833981234,"sku":"4150230","price":113.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a0badca568ffbb1898d59202e58ae8ad_9ad3a46f-08dd-4eea-aa44-c6706ff8c828.jpg?v=1788850180","url":"https:\/\/voomisupply.com\/products\/kennametal-4150230-micro-drill-bit-6-35mm-solid-carbide-b041a","provider":"Voomi Supply","version":"1.0","type":"link"}
