Built to seat size 0 in the GEN2 T-A system, this insert features a 132-degree point angle and an AM300 PVD coating classified at manufacturer grade C2 (K20). The AM300 coating is engineered to extend tool life when cutting through abrasive and difficult-to-machine workpiece materials. At 0.125 inches thick and 0.1 pounds, it is a compact, precision-ground insert intended for use in compatible T-A spade drill bodies. Machinists and CNC operators install this insert as a replaceable cutting element rather than replacing the entire drill body.\u003c\/p\u003e\u003cp\u003eThis insert is rated for use across multiple primary workpiece material categories: stainless steel (M), cast iron (K), non-ferrous metals (N), and super-alloys and titanium (S). That broad material coverage makes it a practical choice for job shops, aerospace machining cells, and heavy manufacturing operations where a single insert style must handle varied material runs. It is part of the GEN2 T-A series, which uses a two-piece modular drill system combining a reusable holder with a replaceable insert for cost-effective drilling at depth.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction at manufacturer grade C2 (K20) for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eAM300 PVD coating extends tool life in stainless steel, cast iron, non-ferrous metals, and titanium-class alloys\u003c\/li\u003e\n\u003cli\u003e132-degree point angle suited for flat-bottom entry and exit characteristics on through-hole and blind-hole applications\u003c\/li\u003e\n\u003cli\u003eSeat size 0, GEN2 T-A series — drop-in replacement for compatible T-A drill bodies without regrinding\u003c\/li\u003e\n\u003cli\u003eThickness of 0.125 inches provides consistent seating depth and insert stability under load\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with GEN2 T-A series spade drill holders accepting seat size 0 inserts.

Always ensure the machine spindle is fully stopped and the machine is in a safe, locked-out state before changing inserts. Use the correct torque wrench and insert screws specified by the holder manufacturer — do not substitute fasteners. Inspect the seat pocket for chips or debris before seating the insert to avoid improper seating and premature insert failure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 37\/64 inches (0.578 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 132 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\u003eCoating\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\u003eSeries\u003c\/strong\u003e: GEN2 T-A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeat Size\u003c\/strong\u003e: 0\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.38 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Stainless Steel, Cast Iron, Non-Ferrous Metal, Super-alloys and Titanium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 4C20P-.578\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ALLIED MACHINE AND ENGINEERING","offers":[{"title":"Default Title","offer_id":51748370415922,"sku":"4C20P-.578","price":96.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7d5c70d1f1658ebed61c28998d024db0_7ed090be-20de-4803-a3cf-f58cbca06fac.jpg?v=1788893027","url":"https:\/\/voomisupply.com\/products\/allied-machine-4c20p-578-spade-drill-insert-37-64-in-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
