Manufactured from CPM-M4 powdered metal, this insert delivers consistent cutting performance across a range of workpiece materials including steel, cast iron, and non-ferrous metals. The 130-degree point angle provides a balanced cutting geometry suited for through-hole and blind-hole applications. With a diameter of 4.5 inches, a height of 3.375 inches, and a thickness of 0.625 inches, this insert seats into a Series G holder. It is installed by machinists and CNC operators in production and job shop environments.\u003c\/p\u003e\n\u003cp\u003eThis spade drill insert is intended for use in industrial drilling operations where large-diameter holes are required without the cost of a solid drill. The uncoated CPM-M4 construction makes it well suited for steel and cast iron applications where regrinding and reconditioning are common practices. It fits Series G spade drill holders and is appropriate for use on CNC machining centers, radial arm drills, and manual boring mills where rigidity and proper coolant delivery are maintained. The package contains one insert.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4.5-inch cutting diameter for large-bore drilling without indexable boring tools\u003c\/li\u003e\n  \u003cli\u003eCPM-M4 powdered metal grade provides high wear resistance and toughness\u003c\/li\u003e\n  \u003cli\u003e130-degree point angle suits general-purpose drilling in steel and cast iron\u003c\/li\u003e\n  \u003cli\u003eUncoated finish allows for field regrinding and reconditioning\u003c\/li\u003e\n  \u003cli\u003eSeries G seat size ensures positive location and repeatable runout in compatible holders\u003c\/li\u003e\n  \u003cli\u003eCompatible with primary workpiece materials: 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 Series G spade drill holders.

Before inserting or removing the spade drill insert, confirm the machine spindle is fully stopped and locked out per OSHA lockout\/tagout procedures. Seat the insert fully into the Series G holder and torque the clamping screws to the holder manufacturer's specification — do not estimate clamp torque by feel on a large-diameter insert. Verify runout at the cutting edge with a dial indicator before initiating a cut, and ensure adequate coolant flow to the cutting zone to prevent premature edge wear.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 4.5 inches\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\u003eSeat Size \/ Series\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\u003eCoating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible 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\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: 10274-0416\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ALLIED MACHINE AND ENGINEERING","offers":[{"title":"Default Title","offer_id":51730425348402,"sku":"10274-0416","price":420.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f5df4c0810f1940502f81bddd412ef6c.jpg?v=1788717223","url":"https:\/\/voomisupply.com\/products\/allied-machine-10274-0416-spade-drill-insert-4-5-in-seat-g","provider":"Voomi Supply","version":"1.0","type":"link"}
