Built on the H1TE series platform, it features a 0.7874-inch (20 mm) mill diameter and a matching 0.7874-inch shank, making it a direct-fit single-end tool for standard toolholders. The four-flute spiral geometry runs with a variable helix angle of 36 to 39 degrees and variable index spacing, both of which work together to reduce chatter and improve surface finish at aggressive feed rates. An AlTiN coating adds thermal resistance and hardness, extending tool life when cutting through tough workpiece materials. Machinists and CNC operators working in production environments will find this end mill suited for continuous or interrupted cuts in hard-to-machine metals.\u003c\/p\u003e\n\u003cp\u003eThis end mill is designed for cutting steel, stainless steel, cast iron, high-temperature alloys, and hardened materials, corresponding to ISO material groups P, M, K, S, and H. It is center-cutting, allowing plunge entry without a pre-drilled pilot hole. The tool provides a 26 mm (approximately 1.02 inches) length of cut and an overall length of 92 mm (approximately 3.62 inches). It does not include through-coolant capability, so flood or mist coolant applied externally is the standard approach on compatible CNC machining centers and manual mills.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction in material grade KCPM15 for rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating provides high-heat resistance for cutting steel, stainless, and hardened materials\u003c\/li\u003e\n  \u003cli\u003eVariable helix (36 to 39 degrees) and variable index geometry reduce harmonic vibration and chatter\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting design allows direct plunge entry into the workpiece\u003c\/li\u003e\n  \u003cli\u003eSingle-end, right-hand cut with right-hand spiral flute for standard spindle rotation\u003c\/li\u003e\n  \u003cli\u003eH1TE series platform with no chipbreaker, suited for smooth continuous chip flow\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers and milling machines accepting a 0.7874-inch (20 mm) shank diameter.

Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool from the toolholder. Verify toolholder runout is within acceptable tolerance before engaging the cut, as excessive runout will accelerate edge wear on carbide tooling. Do not exceed the recommended length of cut of 26 mm to avoid deflection or tool breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.7874 inches (20 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.7874 inches (20 mm)\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: approximately 1.02 inches (26 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: approximately 3.62 inches (92 mm)\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\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenter Cutting\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\u003eChipbreaker\u003c\/strong\u003e: No\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\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: 4.92 inches L x 1.38 inches W x 1.38 inches H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.72 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: KENNAMETAL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6769718\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51742957207858,"sku":"6769718","price":446.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7954dac53ba7721a0191256db04b4f0a_55093612-5106-4b8e-8fe6-26a45adb0e1c.jpg?v=1788840767","url":"https:\/\/voomisupply.com\/products\/kennametal-6769718-square-end-mill-0-7874in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
