Part of the Tiger Tec series, it carries the WKP35S manufacturer grade and features a CVD-applied multilayer coating of TiCN, Al2O3, and TiN for extended tool life and thermal resistance. The insert is square in shape with four cutting edges, an inscribed circle of 0.307 inches (7.8 mm), a thickness of 0.132 inches, and a corner radius of 0.019 inches (0.48 mm). It is designed for indexable drill toolholders used by machinists and toolroom professionals in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThis insert is suited for drilling operations in residential and commercial machining applications where cast iron and steel are the primary workpiece materials. The E57 chipbreaker geometry controls chip flow during deep-hole and through-hole drilling cycles. The square SNMG-style geometry allows four usable cutting edges before replacement, reducing per-hole tooling cost on high-volume runs. Typical applications include component drilling on CNC machining centers and drill press setups where consistent hole quality and tool life are critical.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTiger Tec CVD coating (TiCN, Al2O3, TiN) for heat resistance and flank wear reduction\u003c\/li\u003e\n\u003cli\u003eFour cutting edges per insert for maximum edge utilization\u003c\/li\u003e\n\u003cli\u003eE57 chipbreaker optimized for cast iron and steel chip control\u003c\/li\u003e\n\u003cli\u003eSquare insert shape with 90-degree included angle for stable seating\u003c\/li\u003e\n\u003cli\u003eWKP35S grade rated for both P35 steel and K35 cast iron material groups\u003c\/li\u003e\n\u003cli\u003eMeets ANSI and ISO standards; ISO Code P4841P-4R-E57 WKP35S\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with indexable drill toolholders accepting insert size code 48 square inserts conforming to ANSI and ISO standards; verify holder geometry and pocket dimensions before installation.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInsert indexing and replacement should be performed by a qualified machinist with the spindle locked out and all machine power isolated per facility lockout\/tagout procedures. Use a torque wrench appropriate for the toolholder clamp screw to avoid over-torquing the insert seat. Inspect the insert pocket and clamping components for wear or debris before seating a new insert. Follow the toolholder manufacturer's recommended clamping torque specification for insert size 48 square inserts.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: WKP35S\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Tiger Tec\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Square\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.307 inches (7.8 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.31 inches (7.8 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.31 inches (7.8 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.132 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.019 inches (0.48 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\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 Layers\u003c\/strong\u003e: TiCN, Al2O3, TiN\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\u003eMaterial Grade Codes\u003c\/strong\u003e: P35, K35\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: P4841P-4R-E57 WKP35S\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 48\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.06 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: WALTER\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6169109\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER","offers":[{"title":"Default Title","offer_id":52042152935730,"sku":"6169109","price":338.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/709ee3c77b315caf1efc2f6abdade45a_eb375d82-fb96-45c8-ae21-3399e5167a26.jpg?v=1790028166","url":"https:\/\/voomisupply.com\/products\/walter-6169109-indexable-drill-insert-p48448e57-wkp35s","provider":"Voomi Supply","version":"1.0","type":"link"}
