Designed for the T-A Pro series, this insert measures 18.5mm (0.7283 inches) in diameter and features a 132-degree point angle optimized for clean entry and accurate hole geometry. The AM460 PVD coating provides enhanced surface hardness and heat resistance, extending tool life in difficult cutting conditions. Thickness is 0.1563 inches. Machining professionals and toolroom technicians working with stainless steel and similar hard materials rely on this insert for consistent, repeatable results in production environments.\u003c\/p\u003e\u003cp\u003eThe TAM1-18.50 is intended for use with compatible T-A Pro series spade drill holders accepting a Seat Size 1 insert. Its primary application is drilling stainless steel (ISO material code M), making it well suited for aerospace, food processing, medical device, and industrial fabrication operations where stainless is common. The solid carbide construction is appropriate for CNC machining centers, lathes with live tooling, and other rigid machine tool setups where insert rigidity and cutting-edge integrity are critical.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard materials\u003c\/li\u003e\n\u003cli\u003eAM460 PVD coating engineered for stainless steel and other difficult-to-machine alloys\u003c\/li\u003e\n\u003cli\u003e132-degree point angle for controlled entry and reduced thrust force\u003c\/li\u003e\n\u003cli\u003e18.5mm (0.7283 inch) diameter, Seat Size 1, compatible with T-A Pro series holders\u003c\/li\u003e\n\u003cli\u003eThickness of 0.1563 inches for precise seating in the holder pocket\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with ALLIED MACHINE AND ENGINEERING T-A Pro series spade drill holders requiring a Seat Size 1 insert.

Use the correct torque wrench and insert screws specified by the holder manufacturer — do not overtighten, as this can damage the insert seat or fracture the carbide. Inspect the holder pocket for debris, chips, or wear before seating a new insert. Follow the machine tool manufacturer and cutting tool manufacturer guidelines for speed, feed, and coolant application when programming cuts in stainless steel.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 18.5mm (0.7283 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\u003eCoating\/Finish\u003c\/strong\u003e: AM460\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Classification\u003c\/strong\u003e: PVD\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: T-A Pro\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 Material\u003c\/strong\u003e: Stainless Steel (ISO Code M)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.28 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.97 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1.97 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 pounds\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: TAM1-18.50\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ALLIED MACHINE AND ENGINEERING","offers":[{"title":"Default Title","offer_id":51753213067570,"sku":"TAM1-18.50","price":118.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/be48c3fc3d2b89b10485d25fdcadd30c.jpg?v=1788933953","url":"https:\/\/voomisupply.com\/products\/allied-machine-tam1-18-50-spade-drill-insert-18-5mm-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
