Manufactured from solid carbide and finished with a CVD coating in the WKP25S grade, this insert belongs to the Tiger Tec series and carries the P4840P-8R-E57 ISO code. The E57 chipbreaker geometry promotes controlled chip evacuation and consistent cutting action. With four usable cutting edges per insert, it delivers extended service life per piece and reduced cost per hole. It suits licensed machinists and tooling technicians running indexable drill bodies in production or job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for right-hand cutting applications in primary workpiece materials classified as steel (P) and cast iron (K), corresponding to ISO material grades P25 and K25. It is sized at insert size 8 with a 0.6500-inch inscribed circle and fits drill bodies accepting the P48448E57 seat geometry. Typical use cases include through-hole and blind-hole drilling on CNC machining centers and turning centers where consistent hole quality and tool life are required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction with CVD coating for wear resistance in steel and cast iron\u003c\/li\u003e\n  \u003cli\u003eWKP25S grade covers ISO P25 and K25 material classifications\u003c\/li\u003e\n  \u003cli\u003eE57 chipbreaker promotes controlled chip formation and evacuation\u003c\/li\u003e\n  \u003cli\u003eFour cutting edges per insert for lower cost-per-edge\u003c\/li\u003e\n  \u003cli\u003e90-degree square shape with 0.0394-inch (1.00 mm) corner radius\u003c\/li\u003e\n  \u003cli\u003eCompliant with ANSI and ISO insert standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for indexable drill bodies accepting the P48448E57 seat style, insert size 8, with a 0.6500-inch inscribed circle.

Power down and lock out the machine spindle before seating or rotating any indexable insert. Use the manufacturer-specified torx or hex key to seat the clamping screw; do not use impact tools on insert screws. Inspect the pocket seat for chips or damage before installing a fresh edge, as debris in the pocket will cause premature insert failure or dimensional error.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: P484\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: WKP25S\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Tiger Tec\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: P4840P-8R-E57 WKP25S\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Square\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 48\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.6496 inches (16.50 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.6500 inches (16.50 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.6500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.2177 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0394 inches (1.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: E57\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: CVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Finish\u003c\/strong\u003e: Coated\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\u003ePrimary Workpiece Material Code\u003c\/strong\u003e: K, P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: P25, K25\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 4.21 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: WALTER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6171463\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER","offers":[{"title":"Default Title","offer_id":51973679841586,"sku":"6171463","price":439.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/709ee3c77b315caf1efc2f6abdade45a_f747d11b-5274-47e5-b01f-e18749f4e4b0.jpg?v=1789974169","url":"https:\/\/voomisupply.com\/products\/walter-6171463-indexable-drill-insert-p48448e57-wkp25s","provider":"Voomi Supply","version":"1.0","type":"link"}
