It accepts interchangeable spade drill inserts and delivers repeatable bore diameters from 7\/16 to 1\/2 inches at depths up to 1-1\/4 inches. The holder features a 3\/4-inch flatted cylindrical shank, a body length of 2-1\/32 inches, and an overall length of 4-13\/32 inches. Through-coolant capability is provided via an axial concentric entry port with a 1\/8-inch NPT coolant hole thread. This tool is installed and operated by machinists and tool-and-die professionals in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThe 220Z0S-075L belongs to Allied Machine and Engineering's T-A Z Series and is classified as a short-length spade drill holder. Its straight-flute geometry and through-coolant design make it well suited for general-purpose drilling operations across universal workpiece material categories including steels, stainless, cast iron, nonferrous alloys, high-temperature alloys, and hardened materials. Typical applications include CNC machining centers and drill presses where consistent hole quality and chip evacuation are required. The flatted shank provides positive drive engagement and reduces the risk of shank slippage under cutting loads.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDrill diameter range of 7\/16 to 1\/2 inches accommodates multiple insert sizes within a single holder\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant delivery via axial concentric entry with 1\/8-inch NPT thread for effective chip flushing and tool-life extension\u003c\/li\u003e\n  \u003cli\u003eShort-length classification with 1-1\/4-inch flute length minimizes overhang and improves rigidity\u003c\/li\u003e\n  \u003cli\u003eFlatted cylindrical shank (3\/4 inch diameter, 2-3\/8 inch shank length) for positive rotational drive\u003c\/li\u003e\n  \u003cli\u003eT-A Z Series indexable design allows fast insert indexing without removing the holder from the spindle\u003c\/li\u003e\n  \u003cli\u003eUniversal workpiece material rating (P, M, K, N, S, H) supports use across steel, cast iron, nonferrous, superalloy, and hardened material families\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Allied Machine and Engineering T-A Z Series indexable spade drill inserts compatible with the 220Z0S-075L holder.

Confirm that the coolant supply line thread matches the 1\/8-inch NPT port before connecting through-coolant. Secure the flatted shank in the tool holder to the torque specification listed in the machine or tooling manufacturer documentation. Follow shop safety protocols and applicable OSHA machining standards when handling cutting tools.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Drill Diameter\u003c\/strong\u003e: 7\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drill Diameter\u003c\/strong\u003e: 1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drill Depth\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 4-13\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 2-1\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 2-3\/8 inches\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\u003eDrill Length\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\u003eThrough Coolant\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 inches NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: T-A Z\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: 0.5 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: 220Z0S-075L\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ALLIED MACHINE AND ENGINEERING","offers":[{"title":"Default Title","offer_id":51728422011186,"sku":"220Z0S-075L","price":278.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f7403cb85ea43746e373a4cbc11a6b1f.jpg?v=1788690996","url":"https:\/\/voomisupply.com\/products\/allied-machine-220z0s-075l-indexable-spade-drill-7-16-1-2-in","provider":"Voomi Supply","version":"1.0","type":"link"}
