Built from cobalt with a TiAlN (titanium aluminum nitride) PVD coating, this insert delivers extended tool life and heat resistance at elevated cutting speeds. It measures 21\/32 inch in diameter, features a 132-degree point angle, and fits a Seat Size 0 holder in the T-A spade drill series. At 0.125 inches thick and weighing approximately 0.1 pounds, it is a compact, single-piece insert intended for installation by machinists and tooling technicians in production or job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for drilling into a range of primary workpiece materials including steel, stainless steel, cast iron, super-alloys, titanium, and hard materials. The T-A series is a modular spade drill platform widely used in CNC machining centers, lathes, and drill presses across general manufacturing, aerospace, and heavy-industry applications. The 132-degree point geometry is appropriate for entry into harder materials and cross-hole or interrupted-cut conditions where point stability matters.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e21\/32 inch diameter with 132-degree point angle for stable entry into hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003eCobalt substrate provides toughness and heat resistance beyond standard high-speed steel\u003c\/li\u003e\n  \u003cli\u003eTiAlN PVD coating extends surface hardness and oxidation resistance at high cutting speeds\u003c\/li\u003e\n  \u003cli\u003eSeat Size 0, T-A series compatibility for direct drop-in replacement in matching holders\u003c\/li\u003e\n  \u003cli\u003e0.125 inch insert thickness for consistent seating and repeatable depth control\u003c\/li\u003e\n  \u003cli\u003eRated for steel, stainless steel, cast iron, super-alloys, titanium, and hard materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with T-A series Seat Size 0 spade drill holders.

Before changing inserts, ensure the machine spindle is fully stopped and locked out per applicable machine safety procedures. Seat the insert fully against the holder pocket and torque the clamping screw to the holder manufacturer's specification — do not estimate or over-tighten. Inspect the seat and insert seating surfaces for chips or debris before securing, as improper seating can cause insert movement and tool failure during cutting.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 21\/32 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: Cobalt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN\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: 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\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: 180A-0021\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ALLIED MACHINE AND ENGINEERING","offers":[{"title":"Default Title","offer_id":51730324816178,"sku":"180A-0021","price":64.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c59c5ce13d5cf398c79adf0b24424049_522837cc-056c-405d-ba81-67f95f962800.jpg?v=1788715379","url":"https:\/\/voomisupply.com\/products\/allied-180a-0021-spade-drill-insert-21-32-in-cobalt-tialn","provider":"Voomi Supply","version":"1.0","type":"link"}
