Built to the H1TE series specification, it carries an AlTiN coating that supports elevated cutting temperatures and extends tool life in abrasive applications. The cutting geometry features a variable helix angle between 36 and 39 degrees combined with a variable index, which reduces harmonic vibration and improves surface finish at aggressive feed rates. With a 1 inch diameter, 3 inch length of cut, and 6 inch overall length, this tool is sized for full-depth profiling and slotting operations across a wide range of machining centers.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for CNC vertical and horizontal machining centers in job shop, aerospace, die and mold, and general metalworking environments. The single-end, right-hand cut configuration with a right-hand spiral flute is the standard orientation for conventional and climb milling on ferrous and exotic alloy workpieces. The center-cutting capability allows plunge entry without a pre-drilled pilot hole. Material grade KCPM15 is a fine-grain carbide substrate optimized for high-hardness and high-temperature alloy applications where tool edge retention is critical.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAlTiN coating for extended tool life in high-heat cutting conditions\u003c\/li\u003e\n  \u003cli\u003eVariable helix (36-39 degrees) and variable index geometry reduces chatter and vibration\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting design allows direct plunge entry\u003c\/li\u003e\n  \u003cli\u003eKCPM15 carbide grade optimized for steel, stainless steel, cast iron, high-temp alloys, and hardened materials\u003c\/li\u003e\n  \u003cli\u003eSingle-end, right-hand cut with spiral flute for standard milling setups\u003c\/li\u003e\n  \u003cli\u003eNo chipbreaker and no coolant-through — suited for flood or mist coolant delivery from external sources\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on CNC machining centers accepting a 1 inch straight shank.

Secure the 1 inch shank in a collet chuck, end mill holder, or hydraulic toolholder rated for the shank diameter and confirm runout before cutting. Power down and lock out the spindle before any tool change. Do not exceed the manufacturer-recommended cutting parameters for the workpiece material and coating type; consult KENNAMETAL H1TE series feed and speed data for this grade.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1 inch\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: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 3.734 inches\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\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 36-39 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: Yes\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\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: H1TE\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\u003ePackage Dimensions\u003c\/strong\u003e: 4.33 inches L x 0.98 inches W x 0.98 inches H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.601 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Fractional Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: 6676984\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51729595334962,"sku":"6676984","price":1090.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/07099b445326f4946fe54b0c87bd6159_0a9627d7-efd8-4a16-8560-e7d9a1a41d04.jpg?v=1788706540","url":"https:\/\/voomisupply.com\/products\/kennametal-6676984-square-end-mill-1-in-4-flute-altin-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
