With a 1.30 mm (0.0512 inch) diameter and a 140-degree point angle, this bit delivers clean entry geometry in hard and abrasive materials. The TiAlN coating improves wear resistance and heat tolerance, extending tool life in demanding cutting environments. At 58.00 mm overall length with a 4.00 mm straight-cylindrical shank, it mounts securely in standard toolholders. The tapered web configuration and regular spiral flute promote chip evacuation in short-depth bore applications. This bit is installed by machinists and toolroom technicians working in precision manufacturing, aerospace, electronics, and medical component production.\u003c\/p\u003e\u003cp\u003eThis micro drill bit is suited for applications requiring consistent hole quality in small-diameter, shallow-depth bores. It is intended for use in CNC machining centers, drill presses, and precision benchtop setups where hole diameter accuracy is critical. The maximum drilling depth is 5.00 mm, making it appropriate for through-holes and blind bores in thin workpiece stock. Right-hand cutting direction is standard for conventional spindle rotation. This bit conforms to DIN 6537K specification, aligning it with common European and international tooling standards used across contract machining and high-mix production environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1.30 mm (0.0512 inch) diameter with diameter tolerance of -0.014 to 0.000 mm for tight hole accuracy\u003c\/li\u003e\n\u003cli\u003e140-degree standard point angle for positive entry and reduced thrust force\u003c\/li\u003e\n\u003cli\u003eTiAlN coating for elevated wear resistance and thermal stability\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction provides rigidity and edge retention in hard materials\u003c\/li\u003e\n\u003cli\u003eTapered web with regular spiral flutes supports chip clearance in shallow bores\u003c\/li\u003e\n\u003cli\u003eDIN 6537K compliant for interchangeability with standard tooling systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eThis bit belongs to the KENNAMETAL Series B041A-CPG and is compatible with standard straight-cylindrical toolholders accepting a 4.00 mm shank diameter. It is designed as an OEM-style replacement or production-run drill for precision machining applications using that series specification.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes should be performed with the machine spindle fully stopped and locked out per applicable safety procedures. Use a properly sized collet or drill chuck rated for the 4.00 mm shank to ensure concentric runout. Avoid exceeding the 5.00 mm maximum drilling depth to prevent deflection or tool breakage. Confirm spindle direction is set to right-hand rotation 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: 1.30 mm (0.0512 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\u003eOverall Length\u003c\/strong\u003e: 58.00 mm (2.2835 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 7.00 mm (0.2756 inches)\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\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\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral (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\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\u003eDiameter Tolerance\u003c\/strong\u003e: -0.014 to 0.000 mm\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\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.28 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: 4151632\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51729258414386,"sku":"4151632","price":94.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f094d10e0447e39bb17249e1bf773357.jpg?v=1788702267","url":"https:\/\/voomisupply.com\/products\/kennametal-4151632-micro-drill-bit-1-30mm-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
