Part of the T-A series, this insert features a 132-degree point angle and a PVD-applied TiN (titanium nitride) coating that extends tool life by reducing friction and wear at the cutting edge. The insert measures 29\/32 inches in diameter with a Seat Size 1 designation, and its 0.1563-inch thickness provides consistent seating and repeatable positioning in compatible T-A spade drill holders. Machinists and toolroom professionals typically install and apply this insert in production drilling operations.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for drilling operations across a wide range of workpiece materials, including steel, stainless steel, cast iron, super-alloys, titanium, and hard materials, corresponding to ISO material groups P, M, K, S, and H. Its cobalt substrate provides the heat and wear resistance needed when cutting tough or abrasion-prone materials. The TiN coating adds a secondary layer of protection, making this insert a practical choice for shops running moderate to high-speed drilling cycles on ferrous and exotic-alloy components.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt insert material for elevated heat resistance and edge toughness in hard and abrasive workpieces\u003c\/li\u003e\n  \u003cli\u003eTiN coating applied via PVD process for reduced friction and extended cutting life\u003c\/li\u003e\n  \u003cli\u003e132-degree point angle for efficient chip formation and reduced thrust in through-hole and blind-hole drilling\u003c\/li\u003e\n  \u003cli\u003e29\/32-inch diameter with Seat Size 1 for consistent, repeatable fit in T-A series holders\u003c\/li\u003e\n  \u003cli\u003eCompatible with steel, stainless steel, cast iron, super-alloys, titanium, and hard materials (ISO P, M, K, S, H)\u003c\/li\u003e\n  \u003cli\u003eThickness of 0.1563 inches ensures precise axial positioning within the holder pocket\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.

Always power down and lock out the spindle drive before handling inserts. Inspect the holder pocket for chips, burrs, or wear before seating the insert, and use the appropriate insert screw and torque tool as specified by the holder manufacturer. Handle cutting edges with care to avoid chipping the coating prior to use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 29\/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: 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: Cobalt\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\u003eThickness\u003c\/strong\u003e: 0.1563 inches\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 (ISO P, M, K, S, H)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\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-0029\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ALLIED MACHINE AND ENGINEERING","offers":[{"title":"Default Title","offer_id":51748083138866,"sku":"181T-0029","price":61.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/888efb7f48a8647f85b55bb4451fb710_7c95473a-0c22-4d97-b882-a7729a3b34c4.jpg?v=1788888865","url":"https:\/\/voomisupply.com\/products\/allied-machine-181t-0029-spade-drill-insert-29-32-in-cobalt-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
