Built to DIN 6537K specification, it features a TiAlN coating that extends tool life under high-temperature cutting conditions. The 140-degree drill point angle promotes accurate entry and reduces thrust on thin or hard workpiece materials. At 0.0469 inches (1.19 mm) in diameter, this bit is suited for micro-hole work where dimensional accuracy is critical. It is installed and used by machinists and CNC operators working in tool rooms, production shops, and precision manufacturing environments.\u003c\/p\u003e\u003cp\u003eThe 4151630 is built for right-hand cutting and fits straight-cylindrical tool holders or collet chucks accepting a 4.00 mm shank. With an overall length of 2.2835 inches (58.00 mm) and a flute length of 0.2756 inches (7.00 mm), it is dimensioned for short, stable engagement in vertical machining centers, drill presses, and CNC lathes. A maximum drilling depth of 5.00 mm makes it appropriate for through-holes and shallow blind holes in metals, composites, and other machinable materials. The tapered web configuration and spiral flute geometry support chip evacuation in confined bores.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTiAlN coating improves heat resistance and extends tool life in high-speed cutting\u003c\/li\u003e\n\u003cli\u003e140-degree standard point angle reduces thrust and improves entry accuracy\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction provides rigidity essential at sub-1.5 mm diameters\u003c\/li\u003e\n\u003cli\u003eTapered web with regular spiral flutes promotes reliable chip evacuation\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard collet and drill chuck tooling\u003c\/li\u003e\n\u003cli\u003eDIN 6537K specification ensures dimensional conformance to a recognized standard\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in straight-cylindrical collet chucks and drill chucks accepting a 4.00 mm shank diameter, compatible with CNC machining centers, drill presses, and precision drilling fixtures used in Series B041A-CPG tooling applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and operation of micro drill bits should be performed by qualified machinists or CNC technicians. Ensure the spindle and tool holder are fully powered down and locked out before changing tooling. Verify collet or chuck runout is within acceptable limits before use, as excessive runout at this diameter will cause premature breakage. Follow the machine manufacturer and tooling manufacturer guidelines for speed and feed parameters appropriate to the workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.0469 inches (1.19 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.2835 inches (58.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.2756 inches (7.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 4.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 28.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 5.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\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\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: -0.014 to 0.000 mm\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-CPG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Number\u003c\/strong\u003e: DIN 6537K\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 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: 4151630\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51739533017394,"sku":"4151630","price":94.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/027550a92e9fb7c9c67a753ee7e2e1a8_d67b12d9-7c52-45ab-b1d7-fed74401a4e4.jpg?v=1788815826","url":"https:\/\/voomisupply.com\/products\/kennametal-4151630-micro-drill-bit-0-0469-in-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
