Built to the H1TE series specification, it features a 0.4724 inch (12 mm) cutting diameter matched to a 0.4724 inch (12 mm) shank, a 4-flute spiral geometry with a variable helix angle of 36 to 39 degrees, and a variable index design. The cutting edges carry an AlTiN coating for heat resistance and extended tool life. With a 0.6299 inch (16 mm) length of cut and a 2.874 inch (73 mm) overall length, this is a single-end, right-hand cut tool ready for use in production and job-shop CNC milling operations.\u003c\/p\u003e\u003cp\u003eThis end mill is targeted at machinists and tooling specialists running CNC vertical or horizontal mills. It is rated for steel, stainless steel, cast iron, high-temperature alloys, and hardened materials, covering ISO material codes P, M, K, S, and H. The AlTiN coating and variable helix geometry make it well suited for interrupted cuts, high-speed finishing passes, and general profiling in tough alloys where heat buildup and vibration are primary concerns. Center-cutting capability allows direct plunge entry without a pre-drilled start hole.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAlTiN coating resists heat and abrasion in steel, stainless, cast iron, high-temp alloys, and hardened materials\u003c\/li\u003e\n\u003cli\u003eVariable helix (36 to 39 degrees) and variable index reduce chatter and harmonic vibration\u003c\/li\u003e\n\u003cli\u003e4-flute spiral geometry balances material removal rate with chip evacuation\u003c\/li\u003e\n\u003cli\u003eCenter-cutting design permits direct plunge milling without a pilot hole\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction in material grade KCPM15 for rigidity and edge retention\u003c\/li\u003e\n\u003cli\u003eSingle-end configuration; right-hand flute and right-hand cut\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style solid carbide square end mill in the KENNAMETAL H1TE series, compatible with standard CNC milling machine spindles accepting a 0.4724 inch (12 mm) round shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC tooling technician. Secure the shank in a collet or end mill holder rated for the shank diameter and ensure runout is within acceptable tolerance before cutting. Power down and lock out the spindle before changing tooling. Verify spindle speed, feed rate, and depth of cut against the machine tool builder guidelines and KENNAMETAL H1TE series cutting data before engaging the workpiece.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.4724 inches (12.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.4724 inches (12.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.6299 inches (16.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.874 inches (73.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eCenter Cutting\u003c\/strong\u003e: Yes\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\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\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, High-Temp Alloy, Hardened Materials\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: H1TE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Metric\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.22 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 6769687\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51744004210994,"sku":"6769687","price":179.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7954dac53ba7721a0191256db04b4f0a_2e01ca26-ede6-4318-942a-a61a252f5f80.jpg?v=1788852756","url":"https:\/\/voomisupply.com\/products\/kennametal-6769687-square-end-mill-4-flute-altin-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
