With a 0.5-inch cutting diameter, 1-inch length of cut, and 0.5-inch shank diameter, this single-end mill delivers precise, repeatable results in production environments. The AlTiN coating provides thermal resistance and extended tool life when cutting hard and abrasive materials. The 360-degree variable helix geometry — ranging from 36 to 39 degrees — reduces harmonic vibration and chatter, improving surface finish and chip evacuation. Rated under material grade KCPM15, it is engineered for aggressive feeds and speeds in both roughing and finishing passes.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for milling steel, stainless steel, cast iron, high-temperature alloys, and hardened materials — covering ISO material codes P, M, K, S, and H. The centercutting design allows plunge entry, making it practical for interpolated pocketing and ramping operations. With right-hand cut and right-hand spiral flutes, it is compatible with standard vertical and horizontal CNC machining centers. The H1TE series geometry is targeted at shops running tight-tolerance work in aerospace, die-mold, and general precision machining. The 3-inch overall length fits standard tool holders without extended-reach adapters in most setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eVariable helix angle from 36 to 39 degrees reduces vibration and chatter during cutting\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating improves heat resistance and tool life in ferrous and hardened materials\u003c\/li\u003e\n  \u003cli\u003eCentercutting design supports plunge, ramp, and helical interpolation entry\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction provides rigidity for precision tolerances\u003c\/li\u003e\n  \u003cli\u003e4-flute configuration balances chip clearance with surface finish quality\u003c\/li\u003e\n  \u003cli\u003eVariable index spacing minimizes resonance at high spindle speeds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on CNC machining centers with standard 0.5-inch toolholders.

Ensure the machine spindle is fully stopped and the tool changer is in a safe state before inserting or removing the end mill. Use a calibrated toolholder with proper runout tolerance — excessive runout accelerates flute wear and reduces tool life. Follow shop-standard torque procedures for collet or hydraulic chuck engagement; do not exceed holder manufacturer specifications.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5 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: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 1.4 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\u003eCoating\/Finish\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 36 to 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\u003eMaterial Grade\u003c\/strong\u003e: KCPM15\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\u003ePackage Dimensions\u003c\/strong\u003e: 4.33 inches length x 0.98 inches width x 0.98 inches height\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.236 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Fractional Inch\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: 6676929\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51735928275250,"sku":"6676929","price":210.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/185b934e49f9b4baca52e50e969eca24_6f423124-e933-4a7c-a37c-bebe5854c87b.jpg?v=1788774957","url":"https:\/\/voomisupply.com\/products\/kennametal-6676929-square-end-mill-1-2-in-4-flute-altin-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
