Part of the T-A Series, this insert measures 27\/32 inches in diameter and features a 132-degree point angle for precise, aggressive entry into workpieces. The TiN (titanium nitride) PVD coating reduces friction and extends tool life. At 0.1563 inches thick, it fits Seat Size 1 T-A Series holders. Machinists and toolroom professionals working in production environments install this insert as a replaceable cutting element, eliminating the need to replace the entire drill body when the cutting edge wears.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for drilling steel, stainless steel, cast iron, super-alloys, titanium, and hard materials — covering ISO material groups P, M, K, S, and H. It is a practical choice for job shops and production floors running mixed-material work where a single insert geometry needs to handle a broad range of workpiece materials. The T-A Series spade drill system is a common platform in general machining, turning, and mill-drill operations across both manual and CNC setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e27\/32 inch diameter cutting insert for T-A Series Seat Size 1 holders\u003c\/li\u003e\n  \u003cli\u003e132-degree point angle for fast, decisive entry into workpiece material\u003c\/li\u003e\n  \u003cli\u003eCobalt substrate provides toughness and heat resistance in interrupted cuts\u003c\/li\u003e\n  \u003cli\u003eTiN PVD coating reduces friction and improves wear resistance\u003c\/li\u003e\n  \u003cli\u003e0.1563 inch insert thickness for positive seating in compatible holders\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 1 spade drill holders.

Ensure the drill holder is secured in the spindle and the machine is powered down and locked out before seating or removing the insert. Seat the insert fully and confirm the fastening screw is properly torqued per the holder manufacturer's documentation before resuming operation. Inspect the insert seating pocket for chips or debris before each installation to prevent improper seating.\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\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\u003eSeries\u003c\/strong\u003e: T-A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1563 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN\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: Steel, Stainless Steel, Cast Iron, Super-alloys and Titanium, Hard Material\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: 181T-0027\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ALLIED MACHINE AND ENGINEERING","offers":[{"title":"Default Title","offer_id":51732472365362,"sku":"181T-0027","price":61.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/888efb7f48a8647f85b55bb4451fb710_985e7150-dc00-4aec-9f31-e02d20921bb2.jpg?v=1788743231","url":"https:\/\/voomisupply.com\/products\/allied-machine-181t-0027-spade-drill-insert-27-32-in-cobalt-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
