It measures 3\/4 inch in diameter and seats in a Size 1 holder. The insert is manufactured from M4 grade high speed steel and receives a PVD-applied titanium nitride (TiN) coating for improved wear resistance and tool life. At 0.1563 inches thick with a 132-degree point angle, this insert delivers consistent entry geometry across a range of workpiece materials. It is installed and changed out by machinists and tool-room technicians in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for drilling operations in steel, cast iron, and non-ferrous metals. The T-A series platform is widely used in CNC machining centers, manual lathes, and drilling fixtures where replaceable spade inserts reduce per-hole tooling cost. The 132-degree point angle is a general-purpose geometry that performs well across the primary workpiece material groups listed for this insert. Typical applications include through-hole and blind-hole drilling in medium to heavy material stock.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/4 inch diameter with Size 1 seat fits standard T-A series spade drill holders\u003c\/li\u003e\n  \u003cli\u003eM4 grade high speed steel substrate for toughness in interrupted and continuous cuts\u003c\/li\u003e\n  \u003cli\u003ePVD TiN coating improves surface hardness and reduces built-up edge\u003c\/li\u003e\n  \u003cli\u003e132-degree point angle provides general-purpose entry geometry\u003c\/li\u003e\n  \u003cli\u003e0.1563 inch insert thickness maintains consistent seating and repeatability\u003c\/li\u003e\n  \u003cli\u003eCompatible workpiece materials include steel, cast iron, and non-ferrous metals\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with T-A series spade drill holders accepting a Size 1 seat and 3\/4 inch diameter inserts.

Use the appropriate T-A series insert seating tool or torque wrench as specified by the holder manufacturer to secure the insert without over-torquing the clamping screw. Inspect the holder pocket and clamping components for wear or debris before seating a new insert. Follow the machine shop safety protocols and tool manufacturer guidelines when handling coated cutting inserts.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 3\/4 inch\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 Thickness\u003c\/strong\u003e: 0.1563 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN (Titanium Nitride)\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\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Cast Iron, Non-Ferrous Metal\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: 131T-0024\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ALLIED MACHINE AND ENGINEERING","offers":[{"title":"Default Title","offer_id":51732275200306,"sku":"131T-0024","price":54.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/888efb7f48a8647f85b55bb4451fb710_f6f30d3a-db35-437a-9f9a-701718f40ffc.jpg?v=1788741107","url":"https:\/\/voomisupply.com\/products\/allied-machine-131t-0024-spade-drill-insert-3-4-in-hss-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
