It accepts interchangeable spade drill inserts and covers a drilling diameter range of 31\/32 inches to 1-3\/8 inches with a maximum drill depth of 3 inches. The shank is a 3MT (Morse Taper 3) taper shank measuring 15\/16 inches in diameter and 3-7\/8 inches in length, making it compatible with standard taper-spindle drill presses and machining centers. The straight flute geometry promotes chip evacuation in a variety of materials, and the overall assembly length comes to 6-7\/8 inches. This tool is installed and operated by machinists, tool-and-die technicians, and CNC operators in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThe 21411-0003 belongs to Allied Machine and Engineering Series HP-A (High Performance). The primary workpiece material classification covers universal material groups, including workpiece material codes K, M, N, and P, which correspond broadly to cast iron, stainless and heat-resistant alloys, non-ferrous metals, and steel. It is suited for short-hole drilling applications in both manual and CNC machine tool setups where a taper-shank interface is available. No through-coolant is provided; this tool relies on flood or mist coolant delivered externally.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDrilling diameter range: 31\/32 inches to 1-3\/8 inches\u003c\/li\u003e\n  \u003cli\u003eMaximum drill depth: 3 inches with straight flute geometry for chip clearance\u003c\/li\u003e\n  \u003cli\u003e3MT taper shank for direct mounting in Morse Taper spindles and sleeves\u003c\/li\u003e\n  \u003cli\u003eBody length of 3-23\/32 inches and flute length of 3 inches in a short-length configuration\u003c\/li\u003e\n  \u003cli\u003eHigh-performance HP-A series designation for demanding production applications\u003c\/li\u003e\n  \u003cli\u003eUniversal material compatibility across steel, cast iron, non-ferrous, and stainless alloy workpieces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Allied Machine and Engineering Series HP-A indexable spade drill inserts. Compatible with machine spindles and drill sleeves accepting a 3MT (Morse Taper No. 3) taper shank. No specific model numbers were provided in the product data; verify insert and spindle compatibility with Allied Machine and Engineering documentation before installation.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or CNC operators. Before mounting, ensure the machine spindle is fully powered down and locked out per facility lockout\/tagout procedures. Clean the taper shank and spindle socket thoroughly before seating to ensure proper alignment and to prevent fretting. Do not use this tool with through-spindle coolant systems, as this model does not support coolant-through 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 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 3-23\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 6-7\/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: 3MT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 15\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 3-7\/8 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: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HP-A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Universal (K, M, N, P)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 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: 21411-0003\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ALLIED MACHINE AND ENGINEERING","offers":[{"title":"Default Title","offer_id":51749702205746,"sku":"21411-0003","price":292.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/863bf06ac595fd890ef938900f73af07_887152f0-e777-4032-abe5-b6a463675e06.jpg?v=1788909384","url":"https:\/\/voomisupply.com\/products\/allied-machine-21411-0003-indexable-spade-drill-taper-shank","provider":"Voomi Supply","version":"1.0","type":"link"}
