This single-sided, square-shaped insert features an uncoated micrograin ceramic body in grade KY3500, a positive rake geometry, and a T-land cutting edge style. It carries four cutting edges, a corner radius of 0.0469 inches (1.20 mm), and a nominal thickness of 0.1874 inches. The insert is held in place by screw and is installed by machinists and tooling specialists performing milling operations on cast iron workpieces.\u003c\/p\u003e\u003cp\u003eThis insert is designed for milling applications where cast iron is the primary workpiece material, corresponding to material grade code K. The positive rake and flat-top chip breaker geometry make it well suited to finishing and semi-finishing passes. With a maximum depth of cut of 0.8660 inches and an inscribed circle of 0.5000 inches, this insert fits standard SPGN-style toolholders used in both vertical and horizontal milling setups. It is appropriate for production environments handling gray iron, ductile iron, and similar cast iron alloys.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eUncoated micrograin ceramic body in grade KY3500 for high-speed cast iron cutting\u003c\/li\u003e\n\u003cli\u003eSquare insert shape with 90-degree included angle and four usable cutting edges\u003c\/li\u003e\n\u003cli\u003ePositive rake geometry with T-land cutting edge style for controlled chip formation\u003c\/li\u003e\n\u003cli\u003eCorner radius of 0.0469 inches (1.20 mm) for defined edge preparation\u003c\/li\u003e\n\u003cli\u003eNeutral hand orientation compatible with a wide range of SPGN toolholders\u003c\/li\u003e\n\u003cli\u003eMeets both ANSI and ISO insert standards for interchangeability\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement for SPGN-series milling toolholders requiring a square ceramic insert with a 0.5000-inch inscribed circle and screw-clamping retention.

Use the correct torque wrench and manufacturer-specified clamping screw for the toolholder to avoid insert cracking or seat damage. Inspect the insert pocket and seating surface for chips or debris before seating the insert. Do not exceed the maximum depth of cut rating for the insert grade and toolholder combination.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: SPGN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: SPGN120412T02020\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: SPG433T0820\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Square\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Ceramic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KY3500\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: T-Land\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: Flat Top\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 11.00 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0469 inches (1.20 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1874 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.8660 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double Sided\u003c\/strong\u003e: Single\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: 0.0046 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: 1182893\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51729079533874,"sku":"1182893","price":555.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/feefabde2c13ef180e958d3ffcfa2245.jpg?v=1788699643","url":"https:\/\/voomisupply.com\/products\/kennametal-1182893-ceramic-milling-insert-square-ky3500","provider":"Voomi Supply","version":"1.0","type":"link"}
