With a 1.50 mm (0.0591 inches) cutting diameter and a 140-degree drill point angle, this bit delivers clean entry geometry suited for hard and abrasive workpiece materials. The TiAlN coating improves heat resistance and extends tool life in dry or semi-dry cutting conditions. At 58.00 mm overall length with a 4.00 mm straight-cylindrical shank, it integrates with standard toolholders used in CNC machining centers and drill presses. Machinists and toolroom technicians are the primary users of this bit.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is built for precision hole-making in metals, composites, and other hard materials where small-diameter accuracy is critical. The 9.00 mm spiral flute length and 6.00 mm maximum drilling depth make it suited for shallow through-holes and blind holes in workpieces requiring tight positional tolerances. The right-hand cutting direction is standard for conventional spindle rotation on CNC and manual equipment. It belongs to the KENNAMETAL Series B041A-CPG and conforms to DIN 6537K specification, making it a recognized standard-geometry tool for industrial production and toolroom environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1.50 mm cutting diameter with a diameter tolerance of -0.014 to 0.000 mm for tight hole accuracy\u003c\/li\u003e\n  \u003cli\u003e140-degree standard point angle reduces thrust force on entry\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating provides thermal resistance for extended tool life in high-speed applications\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction delivers rigidity and wear resistance in hard materials\u003c\/li\u003e\n  \u003cli\u003eTapered web configuration adds strength at the drill core\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical 4.00 mm shank fits standard collet and toolholder systems\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 6537K specification for consistent geometry and interchangeability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard-geometry replacement or production drill for CNC machining centers, drill presses, and multi-spindle equipment accepting a 4.00 mm straight-cylindrical shank.

Secure the shank fully in a collet or drill chuck rated for the shank diameter before operating. Verify spindle speed and feed rate are appropriate for the workpiece material and hole depth before engaging the cut. Coolant-through is not supported on this tool; use external coolant or dry cutting as required by the application.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 1.50 mm (0.0591 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: 9.00 mm (0.3543 inches)\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\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral (Regular)\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\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\u003c\/strong\u003e: DIN 6537K\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 4151636\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51739512144178,"sku":"4151636","price":94.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cc3092b08408badd519bfc8fd1bf5cd9.jpg?v=1788815503","url":"https:\/\/voomisupply.com\/products\/kennametal-4151636-micro-drill-bit-1-50mm-carbide-tialn","provider":"Voomi Supply","version":"1.0","type":"link"}
