It features a 3.8 mm diameter, a 140-degree standard point, and a multilayer TiAlN coating that extends tool life in high-temperature cutting environments. The straight cylindrical shank measures 6 mm in diameter. With coolant-through capability, this bit maintains cutting performance during deep-hole operations. It is installed by machinists and tool-and-die professionals working with CNC machining centers and precision drill presses.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for precision hole-making in ferrous and non-ferrous metals where tight diameter tolerances and extended reach are required. The 8xD flute-length-to-diameter ratio and tapered web configuration make it appropriate for deep drilling applications in production and job-shop environments. The right-hand spiral flute promotes effective chip evacuation throughout the cut. Conforming to DIN 6537K, it fits standard straight-shank toolholders used in automated and manual machining setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction in material grade KC7325 for rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003eMultilayer TiAlN coating for high-temperature and abrasion resistance\u003c\/li\u003e\n  \u003cli\u003e140-degree standard point angle for accurate self-centering entry\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports chip removal in deep-hole drilling\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute with regular spiral type promotes consistent chip flow\u003c\/li\u003e\n  \u003cli\u003eTapered web configuration reduces cutting forces at depth\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 6537K specification for dimensional consistency\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit tooling solution for straight-shank drill holders accepting a 6 mm shank diameter in CNC machining centers and conventional drill presses.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists. Ensure the spindle and coolant supply are fully powered down and depressurized before changing tooling. Seat the straight cylindrical shank fully and evenly in a collet or drill chuck rated for the shank diameter before tightening. Verify coolant-through passages are clear and flow is confirmed before beginning production drilling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: B053A-CPG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 3.8 mm (0.1496 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\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: KC7325\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Multilayer TiAlN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 87 mm (3.43 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 49 mm (1.93 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 41 mm (1.61 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6 mm (0.2362 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 36 mm (1.42 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.62 mm (0.0245 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral (Regular)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length to Diameter Ratio\u003c\/strong\u003e: 8xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\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: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0005 to 0.0000 inches (-0.012 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\u003ePackage Weight\u003c\/strong\u003e: 0.05 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: 4149605\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51742532075826,"sku":"4149605","price":219.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5cd08b2d5d544bfb28965121c0413198_64c0643a-7e7e-4cf2-9303-72fd8f71c128.jpg?v=1788838025","url":"https:\/\/voomisupply.com\/products\/kennametal-4149605-taper-length-drill-bit-3-8-mm-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
