Built on the T-A 2 series platform, it accepts interchangeable spade drill inserts and delivers drilling diameters from 31\/32 inch to 1-3\/8 inches with a maximum drill depth of 3-3\/8 inches. The 4MT taper shank mounts directly into compatible taper-shank spindles or drill press quills without an adapter. Through-coolant capability is supported via two radial coolant entry ports with 1\/8-inch NPT threaded holes, allowing cutting fluid delivery at the cutting zone for improved chip evacuation and tool life. The body is constructed of steel and is suited for short-length drilling applications.\u003c\/p\u003e\n\u003cp\u003eThis drill body is intended for use in machining environments where interchangeable insert tooling is preferred over solid drills. Typical applications include production drilling in steel, cast iron, aluminum, non-ferrous metals, and high-temperature alloys, consistent with the universal workpiece material codes P, M, K, N, S, and H. It is installed in machine tools equipped with a 4MT taper spindle, such as drill presses, lathes, and machining centers with taper adapters. The short-length body configuration suits setups where minimizing overhang and maintaining rigidity are priorities. The rotary coolant adapter compatibility designation is 2T-3SR for shops using through-spindle coolant systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDrilling diameter range: 31\/32 inch to 1-3\/8 inches with interchangeable spade inserts\u003c\/li\u003e\n  \u003cli\u003eMaximum drill depth of 3-3\/8 inches in a short-length body configuration\u003c\/li\u003e\n  \u003cli\u003e4MT taper shank for direct mounting in taper-spindle machine tools\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant design with dual radial entry ports, 1\/8-inch NPT threaded\u003c\/li\u003e\n  \u003cli\u003eCompatible with rotary coolant adapter 2T-3SR for through-spindle coolant delivery\u003c\/li\u003e\n  \u003cli\u003eUniversal workpiece material compatibility: P, M, K, N, S, and H classifications\u003c\/li\u003e\n  \u003cli\u003eT-A 2 series platform supports a broad range of Allied insert sizes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with T-A 2 series spade drill inserts from ALLIED MACHINE AND ENGINEERING.

Ensure the machine spindle is fully de-energized and brought to a complete stop before mounting or removing the drill body. Clean the taper shank and spindle bore thoroughly before seating to ensure full taper contact and prevent runout. If using through-coolant, verify NPT port threads are properly sealed and coolant pressure is appropriate for the machine tool before operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Drill Diameter\u003c\/strong\u003e: 31\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drill Diameter\u003c\/strong\u003e: 1-3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drill Depth\u003c\/strong\u003e: 3-3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 10-25\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 4-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3-3\/8 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\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\u003eLength Type\u003c\/strong\u003e: Short\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\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\/8 inches NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRotary Coolant Adapter Compatibility\u003c\/strong\u003e: 2T-3SR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: T-A 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material Codes\u003c\/strong\u003e: P, M, K, N, S, H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: 22020S-004I\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ALLIED MACHINE AND ENGINEERING","offers":[{"title":"Default Title","offer_id":51751955857714,"sku":"22020S-004I","price":354.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0846caa24a32270bd7e3e99514ade0ad.jpg?v=1788924855","url":"https:\/\/voomisupply.com\/products\/allied-machine-22020s-004i-indexable-spade-drill-taper-shank","provider":"Voomi Supply","version":"1.0","type":"link"}
