Built to Series H1TE specifications, it features a 0.625-inch cutting diameter, a 0.75-inch length of cut, and a 3-inch overall length. The AlTiN coating provides thermal resistance and hardness retention at elevated cutting temperatures, making this tool well-suited for aggressive feeds and speeds in difficult-to-machine materials. Four spiral flutes with a variable helix angle of 36 to 39 degrees and variable index geometry work together to reduce chatter and improve surface finish. The single-end, right-hand cut configuration is compatible with standard vertical and horizontal milling setups.\u003c\/p\u003e\n\u003cp\u003eThis end mill is intended for cutting steel, stainless steel, cast iron, high-temperature alloys, and hardened materials, covering ISO material codes P, M, K, S, and H. It is centercutting, allowing plunge entry in addition to peripheral and slot milling. The regular-length body and 0.625-inch shank diameter make it a straightforward fit for standard collet chucks and end mill holders used in CNC machining centers and manual knee mills. Material grade KCPM15 provides the substrate toughness and wear resistance needed for interrupted cuts and multi-material production runs. No coolant-through feature is present; external flood or mist coolant is the appropriate delivery method for this tool.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAlTiN coating for high-heat resistance and extended tool life in ferrous and hard materials\u003c\/li\u003e\n  \u003cli\u003eVariable helix (36 to 39 degrees) and variable index geometry reduce vibration and chatter\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n  \u003cli\u003eSolid carbide KCPM15 substrate for toughness in interrupted and continuous cuts\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flutes with right-hand cut for standard milling machine compatibility\u003c\/li\u003e\n  \u003cli\u003eSingle-end configuration; 0.75-inch length of cut and 1.1095-inch neck length\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with steel, stainless steel, cast iron, high-temperature alloys, and hardened materials as listed in the Series H1TE product family.

Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool from the holder. Secure the shank to the full recommended engagement depth in the collet or holder to minimize runout and tool pull-out risk. Follow the machine tool manufacturer and KENNAMETAL speed-and-feed guidelines for the specific workpiece material before cutting.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.625 inches (5\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.75 inches (3\/4 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.625 inches (5\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 1.1095 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003eCentercutting\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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: KCPM15\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel; Stainless Steel; Cast Iron; High-Temp Alloy; Hardened Materials\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: H1TE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Fractional Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.384 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 4.33 inches L x 0.98 inches W x 0.98 inches H\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: 6676975\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51727142519090,"sku":"6676975","price":298.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/07099b445326f4946fe54b0c87bd6159.jpg?v=1788673956","url":"https:\/\/voomisupply.com\/products\/kennametal-6676975-square-end-mill-0-625in-4-flute-altin-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
