Built from solid carbide material grade KC7325 and coated with a multilayer TiAlN finish, this bit is designed to handle demanding materials including hardened steels and high-temperature alloys. It features a 140-degree standard point angle for accurate entry and reduced thrust, a spiral flute with tapered web configuration for chip evacuation, and through-coolant capability to manage heat at the cutting edge. The straight cylindrical shank measures 6 mm in diameter, and the overall length is 94 mm (3.75 inches).\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for CNC machining centers, drill presses, and precision boring setups in industrial, aerospace, automotive, and general metalworking environments. The B053A-CPG series is built to DIN 6537K specification, making it a direct fit for toolholders dimensioned to that standard. The 8xD flute-length-to-diameter ratio and 48 mm maximum drilling depth make it a reliable choice for moderate-depth hole production where dimensional accuracy and tool life are priorities. Machinists and tooling specialists performing close-tolerance work will find the tight diameter tolerance of -0.012 to 0.000 mm appropriate for finish-quality bores.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction in material grade KC7325 for extended tool life in ferrous and hardened materials\u003c\/li\u003e\n  \u003cli\u003eMultilayer TiAlN coating reduces thermal wear and improves performance at elevated cutting speeds\u003c\/li\u003e\n  \u003cli\u003e140-degree standard point angle minimizes drill walk and reduces entry burr\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant design delivers cutting fluid directly to the tip for heat control and chip flushing\u003c\/li\u003e\n  \u003cli\u003eTapered web configuration improves chip flow in the spiral flute channel\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 6537K specification for consistent toolholder compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in toolholders and chucks accepting a 6 mm straight cylindrical shank per DIN 6537K specification.

Ensure the chuck or toolholder collet is clean and properly torqued to the tool manufacturer specifications before operation. Through-coolant lines should be checked for blockage before use to maintain effective heat dissipation. Do not exceed the maximum drilling depth of 48 mm without retracting and clearing chips.\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: 5.2 mm (0.2047 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\u003ePoint Type\u003c\/strong\u003e: Standard\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\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\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\u003eFlute Length\u003c\/strong\u003e: 56 mm (2.2047 inches)\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\u003eOverall Length\u003c\/strong\u003e: 94 mm (3.75 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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 (1.4173 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 48 mm (1.8898 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.87 mm (0.0341 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.012 to 0.000 mm (-0.0005 to 0.0000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\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: 0.01 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: 4149629\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51739637252402,"sku":"4149629","price":268.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5cd08b2d5d544bfb28965121c0413198_5e0d4124-775f-4c65-a10a-4c6799f37e10.jpg?v=1788817215","url":"https:\/\/voomisupply.com\/products\/kennametal-4149629-taper-length-drill-bit-5-2-mm-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
