Built from solid carbide and coated with AlTiN, this head delivers extended tool life and thermal resistance during dry or near-dry cutting. The 3\/8-inch (0.3750-inch) mill diameter and 9\/16-inch (0.5625-inch) length of cut make it well suited for slotting, profiling, and peripheral milling in ferrous and non-ferrous materials. It connects via Duo-Lock 10, the Kennametal quick-change coupling system designed for rigid, repeatable head-to-shank attachment. The variable helix design (36 to 39 degrees) and variable index reduce chatter and improve surface finish. Installed by machining professionals in CNC milling applications.\u003c\/p\u003e\n\u003cp\u003eThis end mill head is intended for single-end use in CNC machining centers where the Duo-Lock 10 modular system is in use. The center-cutting geometry allows plunge entry as well as conventional side milling. The right-hand cutting and right-hand flute direction suit standard spindle configurations. The 4-flute count and AlTiN finish coating make this head appropriate for higher-speed finishing and semi-finishing passes in steel, stainless, and hardened materials where heat resistance and edge retention are priorities.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003eAlTiN finish coating for high-temperature and abrasion resistance\u003c\/li\u003e\n  \u003cli\u003eVariable helix angle (36 to 39 degrees) reduces vibration and chatter\u003c\/li\u003e\n  \u003cli\u003eVariable index geometry improves surface finish quality\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting design allows plunge milling entry\u003c\/li\u003e\n  \u003cli\u003eDuo-Lock 10 connection for fast, repeatable head changes without full tool replacement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with Duo-Lock 10 modular milling shanks in the Kennametal Harvi I TE series.

Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing heads. Use the appropriate Duo-Lock torque tool to seat and secure the head to the shank body. Do not use impact tools or substitute drivers during assembly.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 9\/16 inch (0.5625 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.3346 inches (33.9000 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Duo-Lock 10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Square End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenter Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 36 to 39 degrees (Variable)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: KENNAMETAL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6953266\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51754233725234,"sku":"6953266","price":118.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/790f25226f8faa2b4635c17b3b1dfeb9.jpg?v=1788944015","url":"https:\/\/voomisupply.com\/products\/kennametal-6953266-square-end-mill-head-3-8-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
