It accepts interchangeable spade drill inserts and delivers precise, repeatable drilling performance in production environments. The 220Z0S-075F covers a diameter range of 7\/16 to 1\/2 inches with a maximum drill depth of 1-1\/4 inches. The body measures 2-13\/32 inches in length with an overall length of 4-7\/16 inches. Through-coolant capability with axial concentric entry keeps the cutting zone clear and extends insert life during continuous drilling cycles. Machinists and tooling specialists working in job shops or production facilities are the primary users of this holder.\u003c\/p\u003e\n\u003cp\u003eThe 220Z0S-075F is suited for drilling operations in steel, cast iron, aluminum, non-ferrous alloys, and high-temperature alloys — reflecting its universal primary workpiece material classification (codes H, K, M, N, P, S). Its short-series designation makes it appropriate for applications where rigidity and reduced overhang are priorities, such as vertical machining centers, CNC lathes with driven tooling, and manual knee mills. The flatted cylindrical shank with a 3\/4-inch diameter provides secure tool holding in standard ER collet chucks and milling chucks that accommodate flatted shanks.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDiameter range of 7\/16 to 1\/2 inches accommodates common bore sizes in a single holder body\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant via axial concentric entry (1\/8-inch coolant hole thread size) for effective chip evacuation and heat control\u003c\/li\u003e\n  \u003cli\u003eStraight flute geometry suited for general-purpose drilling in universal workpiece materials\u003c\/li\u003e\n  \u003cli\u003eShort-series body length of 2-13\/32 inches reduces deflection and improves hole straightness\u003c\/li\u003e\n  \u003cli\u003eFlatted 3\/4-inch cylindrical shank provides positive drive and prevents shank rotation under load\u003c\/li\u003e\n  \u003cli\u003eT-A Z series design compatible with Allied Machine indexable spade drill inserts\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eThe 220Z0S-075F is a T-A Z series holder designed to accept Allied Machine and Engineering indexable spade drill inserts for the 7\/16 to 1\/2-inch diameter range.

Ensure the machine spindle is fully stopped and the tool changer or spindle is locked out before mounting or removing the holder. Verify that the toolholder bore and collet or chuck are clean and free of chips before seating the shank. Confirm coolant line connection and flow before running through-coolant cycles to prevent blockage or pressure loss at the insert.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Drill Diameter\u003c\/strong\u003e: 0.4375 inches (7\/16)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drill Diameter\u003c\/strong\u003e: 0.5 inches (1\/2)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drill Depth\u003c\/strong\u003e: 1.25 inches (1-1\/4)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 4.4375 inches (4-7\/16)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 2.40625 inches (2-13\/32)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.25 inches (1-1\/4)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.75 inches (3\/4)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 2.03125 inches (2-1\/32)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Flatted Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: T-A Z\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length\u003c\/strong\u003e: Short\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: Axial Concentric Entry\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Hole Thread Size\u003c\/strong\u003e: 1\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Universal (H, K, M, N, P, S)\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: 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: 220Z0S-075F\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ALLIED MACHINE AND ENGINEERING","offers":[{"title":"Default Title","offer_id":51748585832754,"sku":"220Z0S-075F","price":279.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c613da677a5e16173798cb51cc4ae3f8.jpg?v=1788895435","url":"https:\/\/voomisupply.com\/products\/allied-machine-220z0s-075f-indexable-spade-drill-7-16-1-2-in","provider":"Voomi Supply","version":"1.0","type":"link"}
