At 1.60 mm (0.0630 inches) in diameter, it features a 140-degree drill point angle and a TiAlN coating that extends tool life under high-heat cutting conditions. The overall length is 58.00 mm (2.2835 inches), with a straight-cylindrical shank measuring 4.00 mm in diameter and 28.00 mm in length. Built to DIN 6537K specification, this drill is suited for CNC machining centers and precision drilling cells where tight tolerances and consistent hole geometry are required.\u003c\/p\u003e\n\u003cp\u003eThis micro drill bit is used in precision metalworking and manufacturing environments, including aerospace, automotive, medical device, and general machining. It is appropriate for drilling small-diameter through-holes and blind holes in ferrous and non-ferrous metals where dimensional accuracy is critical. The 1.60 mm diameter and 6.00 mm maximum drilling depth make it a practical tool for fine-feature workpieces. Coolant-through capability supports chip evacuation and thermal management in high-cycle production drilling. The Series B051A-CPG designation identifies it within the KENNAMETAL standard micro drill line.\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 materials\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating for elevated heat resistance and extended tool life\u003c\/li\u003e\n  \u003cli\u003e140-degree drill point angle for reduced thrust and accurate entry\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design aids chip clearing and temperature control\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank (4.00 mm) for standard collet and chuck compatibility\u003c\/li\u003e\n  \u003cli\u003eTapered web configuration reduces walking and improves point stability\u003c\/li\u003e\n  \u003cli\u003eBuilt to DIN 6537K specification for consistent dimensional conformance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard production micro drill for CNC machining centers and drill presses accepting a 4.00 mm straight-cylindrical shank, within the KENNAMETAL Series B051A-CPG product line.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or tooling technician. Secure the shank fully into a collet or precision drill chuck, ensuring runout is within the tolerance required for the application before engaging the spindle. Power down and lock out the machine before changing tooling. Do not exceed the 6.00 mm maximum drilling depth rating, and always verify coolant flow is active when using the through-coolant channel to prevent premature tool failure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 1.60 mm (0.0630 inches)\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: 9.00 mm (0.3543 inches)\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: 6.00 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\u003c\/strong\u003e: TiAlN\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\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\u003eSpecification Number\u003c\/strong\u003e: DIN 6537K\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: B051A-CPG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.11 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: 4148805\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51747078635826,"sku":"4148805","price":124.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/df539f0f84b6f90b0ecf02c0c4f8c0bf.jpg?v=1788875814","url":"https:\/\/voomisupply.com\/products\/kennametal-4148805-micro-drill-bit-1-60mm-solid-carbide-tialn","provider":"Voomi Supply","version":"1.0","type":"link"}
