It accepts spade drill inserts and drills diameters from 1-29\/32 inches to 2-9\/16 inches, with a maximum drill depth of 9-1\/8 inches. The straight flute geometry and 4MT taper shank make it a direct-mount solution for taper-spindle machines without the need for an adapter chuck. Through-coolant capability via dual radial entry ports supports chip evacuation and tool life in demanding production environments. Installed by machinists and tool-and-die professionals in metalworking shops.\u003c\/p\u003e\n\u003cp\u003eThe 24040S-004I is rated for general-purpose drilling across universal workpiece material categories, including steel, cast iron, non-ferrous metals, and high-temperature alloys. Its standard-length body and 9-1\/8-inch flute length suit it for intermediate-depth holes in structural components, flanges, and heavy machine parts. The 4MT taper shank seats directly into compatible taper-spindle lathes, mills, and radial arm drills. Coolant ports are threaded 1\/4 inch NPT and are compatible with the 2T-4SR rotary coolant adapter for live-spindle applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDrilling range from 1-29\/32 inches to 2-9\/16 inches accommodates multiple insert sizes in one holder\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant via 2-radial entry ports with 1\/4 inch NPT threaded coolant holes\u003c\/li\u003e\n  \u003cli\u003e4MT taper shank for direct mounting in compatible taper-spindle machines\u003c\/li\u003e\n  \u003cli\u003eStraight flute design promotes chip flow and reduces cutting forces in through-holes\u003c\/li\u003e\n  \u003cli\u003eCompatible with 2T-4SR rotary coolant adapter for live-spindle setups\u003c\/li\u003e\n  \u003cli\u003eGeneral-purpose rating covers steel, cast iron, non-ferrous, and superalloy materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with T-A 4 Series spade drill inserts.

Before mounting, ensure the machine spindle and taper bore are clean and free of burrs to achieve full taper contact. Power down and lock out the machine before seating or removing the shank. Coolant lines should be connected and pressure-tested before running through-coolant to confirm there are no leaks at the NPT fittings.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Drill Diameter\u003c\/strong\u003e: 1-29\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drill Diameter\u003c\/strong\u003e: 2-9\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drill Depth\u003c\/strong\u003e: 9-1\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 9-1\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 10-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 4-7\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 17-1\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Taper\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Taper Size\u003c\/strong\u003e: 4MT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1.2310 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Entry Style\u003c\/strong\u003e: 2-Radial Entry\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Hole Thread Size\u003c\/strong\u003e: 1\/4 inch NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRotary Coolant Adapter Compatibility\u003c\/strong\u003e: 2T-4SR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: T-A 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2 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: 24040S-004I\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ALLIED MACHINE AND ENGINEERING","offers":[{"title":"Default Title","offer_id":51750422741298,"sku":"24040S-004I","price":470.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/46c3c0d5365e44ab0a79d302fcb18e54.jpg?v=1788915411","url":"https:\/\/voomisupply.com\/products\/allied-machine-24040s-004i-indexable-spade-drill-taper-shank","provider":"Voomi Supply","version":"1.0","type":"link"}
