Built from solid carbide and coated with multilayer TiAlN, it delivers heat resistance and extended tool life in demanding production environments. The bit measures 8.70 mm in diameter with an overall length of 89.00 mm and features a 140-degree split point for accurate entry and reduced thrust. A web-thinned, parallel-web geometry minimizes walking and improves chip evacuation. This bit is sized for use in CNC machining centers, drill presses, and screw machine applications where consistent hole quality and tool longevity are priorities. Installation is performed by machinists and tool-setup technicians in light to heavy manufacturing settings.\u003c\/p\u003e\u003cp\u003eThe 2425143 is suited for drilling cast iron and steel in production-volume environments. Its screw machine length profile provides added rigidity compared to jobber-length bits, making it well-matched for short, precise holes in tight setups. The straight cylindrical shank measures 10.00 mm in diameter, compatible with standard collet chucks and drill chucks used in CNC and manual machining operations. The two-flute regular spiral design supports consistent chip removal during through and blind-hole drilling. Maximum recommended drilling depth is 35.00 mm.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in ferrous materials\u003c\/li\u003e\n\u003cli\u003eMultilayer TiAlN coating improves heat resistance and extends tool life at elevated cutting speeds\u003c\/li\u003e\n\u003cli\u003e140-degree standard point angle reduces thrust and improves entry accuracy\u003c\/li\u003e\n\u003cli\u003eWeb-thinned parallel web minimizes walking and lowers cutting forces\u003c\/li\u003e\n\u003cli\u003eScrew machine length body provides greater rigidity than jobber-length alternatives\u003c\/li\u003e\n\u003cli\u003eConforms to DIN 6537K specification for consistent dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for drilling cast iron and steel workpieces.

Secure the shank fully in the collet or drill chuck and verify runout before cutting. Ensure the machine spindle is at a complete stop before tool changes. Follow the machine manufacturer and tooling manufacturer feed and speed recommendations for the specific workpiece material to avoid premature tool wear or breakage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 8.70 mm (0.3425 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 89.00 mm (3.5039 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 10.00 mm (0.3937 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 40.00 mm (1.5748 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 47.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 35.00 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\u003eDrill Point Length\u003c\/strong\u003e: 1.50 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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 Multilayer\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0.006 to +0.021 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: DIN 6537K\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: B966\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1576 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: 2425143\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51727148319026,"sku":"2425143","price":167.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b10c5eabfad9a2dfaaa64092b85ee0e8.jpg?v=1788674030","url":"https:\/\/voomisupply.com\/products\/kennametal-2425143-screw-machine-drill-bit-8-70mm-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
