Built to GEN3SYS XT series specifications, this insert features a 140-degree point angle and an AM300 PVD coating that extends tool life in abrasive and hard-to-machine materials. At 7\/8 inch in diameter with a seat size 22, it fits directly into compatible GEN3SYS XT spade drill holders. The C2 (K20) carbide grade provides the hardness and edge retention required when drilling stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. Machinists and tooling professionals in production shops and job shops rely on this insert for consistent hole quality across difficult workpiece materials.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for both roughing and finishing drilling operations in CNC machining centers and drill presses where high feed rates and extended tool life are priorities. Primary workpiece material compatibility includes stainless steel (ISO M), cast iron (ISO K), non-ferrous metals (ISO N), and superalloys and titanium (ISO S). It is appropriate for both light production and heavy-duty industrial drilling environments where tooling consistency directly impacts cycle time and part quality.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction in C2 (K20) grade for hardness and wear resistance in difficult materials\u003c\/li\u003e\n  \u003cli\u003eAM300 PVD coating reduces friction and heat buildup, extending insert life in stainless steel and superalloy applications\u003c\/li\u003e\n  \u003cli\u003e140-degree point angle optimizes chip formation and reduces thrust force at entry\u003c\/li\u003e\n  \u003cli\u003eGEN3SYS XT series design for precise, repeatable seating in compatible spade drill holders\u003c\/li\u003e\n  \u003cli\u003eRated for stainless steel, cast iron, non-ferrous metals, superalloys, and titanium workpieces\u003c\/li\u003e\n  \u003cli\u003eCompact geometry: 1.75 inches length, 1.63 inches width, 0.75 inches height\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with GEN3SYS XT series spade drill holders accepting a seat size 22 and a 7\/8 inch diameter insert.

Always power down and lock out the machine spindle before removing or seating an insert. Use the correct torque wrench and insert screw specified by the holder manufacturer — do not over-torque the clamping screw, as carbide inserts are brittle and can fracture under excessive clamp force. Inspect the holder seat for chips, burrs, or damage before seating the new insert to ensure accurate positioning and safe operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 7\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeat Size\u003c\/strong\u003e: 22\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 140 degrees\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: C2 (K20)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: GEN3SYS XT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: AM300\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Classification\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Stainless Steel, Cast Iron, Non-Ferrous Metal, Superalloys and Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.63 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDecimal Height\u003c\/strong\u003e: 0.51 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.029 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: ALLIED MACHINE AND ENGINEERING\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7C222P-0028\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ALLIED MACHINE AND ENGINEERING","offers":[{"title":"Default Title","offer_id":51728889643314,"sku":"7C222P-0028","price":161.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/09d3ebec1a4786f21f23edebed645391_0949e940-65ac-4b52-9915-40bed76ac17b.jpg?v=1788697422","url":"https:\/\/voomisupply.com\/products\/allied-machine-7c222p-0028-spade-drill-insert-7-8-in-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
