Built from M4-grade high speed steel with a PVD-applied TiN (titanium nitride) coating, this insert delivers wear resistance and extended tool life in demanding drilling applications. The 24 mm cutting diameter and 132-degree point angle make it well-suited for initiating and completing through-holes in a wide range of workpiece materials. At 0.1563 inches thick and weighing 0.1 pounds, the insert seats securely in a Seat Size 1 holder body. Machinists and tooling specialists install this insert as a direct replacement or initial setup component in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThe 131T-24 is intended for drilling operations on steel, cast iron, and non-ferrous metals, covering ISO material classifications P, K, and N. It fits standard T-A series Seat Size 1 holder bodies and is appropriate for both CNC machining centers and manual drill press setups where spade drill tooling is specified. Typical applications include through-hole and blind-hole drilling in structural and alloy steels, gray and ductile cast iron, aluminum, and copper alloys. This insert is packaged individually and ordered in single-unit quantities.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e24 mm cutting diameter with a 132-degree point angle for accurate hole entry and chip control\u003c\/li\u003e\n\u003cli\u003eM4-grade high speed steel substrate provides toughness in interrupted and continuous cuts\u003c\/li\u003e\n\u003cli\u003ePVD TiN coating reduces friction and extends insert life across multiple workpiece materials\u003c\/li\u003e\n\u003cli\u003eSeat Size 1 profile ensures precise seating and repeatability in compatible T-A holder bodies\u003c\/li\u003e\n\u003cli\u003eRated for steel, cast iron, and non-ferrous metal workpieces (ISO P, K, N classifications)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with T-A series spade drill holder bodies using Seat Size 1.

Before changing inserts, ensure the machine spindle is fully stopped and locked out per applicable safety procedures. Seat the insert fully into the holder body and secure the clamping screw to the holder manufacturer's specified torque using appropriate hex-key tooling. Inspect the seating surface and insert pocket for chips or debris before each installation to ensure proper contact and runout control.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 24 mm\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: 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\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\u003eThickness\u003c\/strong\u003e: 0.1563 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Cast Iron, Non-Ferrous Metal (ISO P, K, N)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\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: 131T-24\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ALLIED MACHINE AND ENGINEERING","offers":[{"title":"Default Title","offer_id":51737001558322,"sku":"131T-24","price":53.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/888efb7f48a8647f85b55bb4451fb710_60390146-b435-4dcc-b3e0-46e2412c096d.jpg?v=1788782996","url":"https:\/\/voomisupply.com\/products\/allied-machine-131t-24-spade-drill-insert-24mm-hss-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
