It measures 4 inches in diameter with a 130-degree point angle, and is manufactured from CPM-M4 powdered metal for consistent edge integrity and wear resistance in production environments. The insert seats into a Size G holder and arrives uncoated, making it suitable for use with cutting fluids or where coating-related adhesion concerns apply. This insert is installed by machinists and toolroom professionals working with CNC machining centers, horizontal boring mills, and large-capacity drill presses.\u003c\/p\u003e\u003cp\u003eThis spade drill insert is intended for deep-hole and large-diameter drilling in steel, cast iron, and non-ferrous metals. Its 4-inch diameter and powdered metal construction make it a practical choice for production shops and job shops that require reliable hole geometry at larger diameters without the cost of solid carbide tooling. The uncoated surface allows for straightforward regrinding when edge wear occurs, extending total tool life in high-volume applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4-inch diameter with 130-degree point angle for aggressive material entry and chip formation\u003c\/li\u003e\n\u003cli\u003eCPM-M4 powdered metal grade delivers uniform carbide distribution and improved toughness over standard M4 high-speed steel\u003c\/li\u003e\n\u003cli\u003eUncoated finish supports easy regrinding and compatibility with flood coolant systems\u003c\/li\u003e\n\u003cli\u003eSeat Size G interface ensures positive location and repeatability in compatible Allied Machine holders\u003c\/li\u003e\n\u003cli\u003eRated for use in steel (P), cast iron (K), and non-ferrous metals (N) work materials\u003c\/li\u003e\n\u003cli\u003e0.625-inch thickness with 3.375-inch height provides substantial insert body for deep-drilling stability\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Allied Machine and Engineering Size G spade drill holders.

Ensure the machine spindle and workholding are fully stopped and de-energized before changing inserts. Inspect the seat pocket for chips, burrs, or wear before seating the insert, as debris under the insert body can cause deflection and premature failure. Follow applicable machine shop safety standards and the tool manufacturer guidelines for coolant pressure and feed rate selection.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeat Size\u003c\/strong\u003e: G\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 130 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Powdered Metal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: CPM-M4\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: Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 3.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Cast Iron, Non-Ferrous Metal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 10274-0400\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ALLIED MACHINE AND ENGINEERING","offers":[{"title":"Default Title","offer_id":51737242042674,"sku":"10274-0400","price":374.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f5df4c0810f1940502f81bddd412ef6c_148f4098-f379-4a8d-bf13-1512a14345d0.jpg?v=1788785983","url":"https:\/\/voomisupply.com\/products\/allied-machine-10274-0400-spade-drill-insert-4-in-seat-g","provider":"Voomi Supply","version":"1.0","type":"link"}
