Built to the GEN2 T-A series standard, this insert features a 132-degree point angle and a Seat Size 1 body, measuring 0.1563 inches thick. The AM300 PVD coating provides thermal and wear resistance, extending tool life in abrasive and difficult-to-machine workpiece materials. Machinists and tool-crib technicians working in production or job-shop environments install this insert as a replaceable cutting element within a compatible T-A spade drill holder.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for drilling stainless steel, cast iron, non-ferrous metals, and super-alloys including titanium. The 132-degree point geometry is selected for these material groups because it manages heat and chip formation in materials that work-harden or generate high cutting forces. The GEN2 T-A series is a modular drill system where the insert seats into a reusable holder body, allowing the cutting edge to be replaced without replacing the entire tool assembly. Typical applications include production machining centers, CNC turning centers, and manual mills in industrial and tooling environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction with C2 (K20) material grade for hardness and wear resistance\u003c\/li\u003e\n  \u003cli\u003eAM300 PVD coating classification for extended performance in stainless steel, cast iron, non-ferrous metals, and super-alloys\u003c\/li\u003e\n  \u003cli\u003e132-degree point angle optimized for the designated primary workpiece materials\u003c\/li\u003e\n  \u003cli\u003e27\/32 inch cutting diameter, Seat Size 1 — matches corresponding GEN2 T-A series holder seat\u003c\/li\u003e\n  \u003cli\u003eModular insert design reduces tooling cost by replacing only the cutting element\u003c\/li\u003e\n  \u003cli\u003ePackage quantity of 1 insert per unit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with GEN2 T-A series spade drill holders accepting a Seat Size 1 insert at 27\/32 inch diameter.

Power down and lock out the machine spindle before changing the insert. Ensure the holder seat is clean and free of chips or debris before seating the insert, as contamination can cause improper seating and premature failure. Follow the holder manufacturer's published clamping specifications — do not over-torque the clamping screw.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 27\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeat Size\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: GEN2 T-A\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\/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\u003eThickness\u003c\/strong\u003e: 0.1563 inches\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\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\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 4C21P-0027\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ALLIED MACHINE AND ENGINEERING","offers":[{"title":"Default Title","offer_id":51730446811442,"sku":"4C21P-0027","price":108.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a4b2f464f2c60342200b48429b90a7fc_e70a23cd-d72b-471c-a7ae-077529faf94d.jpg?v=1788717630","url":"https:\/\/voomisupply.com\/products\/allied-machine-4c21p-0027-spade-drill-insert-27-32-in-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
