Built to the H1TE series specification, it features a 1-inch mill diameter, 4-inch length of cut, and 7-inch overall length with a 1-inch straight-cylindrical shank. The four-flute geometry runs a variable helix in the 36 to 39 degree range and a variable index pitch, reducing harmonic chatter during aggressive cuts. An AlTiN PVD coating delivers thermal and oxidation resistance at elevated cutting temperatures. The 45-degree chamfer at 0.0200 inches width breaks edges cleanly in a single pass. Licensed machinists and CNC tool-and-die professionals are the primary installers and operators.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for both roughing and finishing operations on steel, stainless steel, cast iron, superalloys, titanium, and hard materials. Rated application operations include shouldering, slotting, ramp-down entry, helical interpolation, drill-mill use, and plunging and recessing. The center-cutting geometry permits direct plunge entry without a pre-drilled pilot hole, making it practical for 3- and 5-axis machining centers running continuous or interrupted cuts across a wide range of workpiece hardness levels.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eVariable helix (36 to 39 degrees) and variable index pitch minimize vibration and chatter during deep cuts\u003c\/li\u003e\n\u003cli\u003eAlTiN PVD coating provides high-temperature oxidation resistance for extended tool life in ferrous and hard materials\u003c\/li\u003e\n\u003cli\u003e45-degree corner chamfer at 0.0200 inches width for consistent edge-breaking in one pass\u003c\/li\u003e\n\u003cli\u003eCenter-cutting design allows direct plunge entry without a pilot hole\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction (material grade KCPM15) maintains rigidity and edge integrity at high surface footage\u003c\/li\u003e\n\u003cli\u003eSingle-end, right-hand cut, right-hand flute direction for standard CNC spindle use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard straight-bore tool holders accepting a 1-inch cylindrical shank. Primary workpiece materials are steel, stainless steel, cast iron, superalloys and titanium, and hard materials (ISO material codes P, M, K, S, H). Catalog reference number H1TE4CH1000X400HA is noted by the manufacturer for cross-reference purposes.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and operation should be performed by qualified machinists following shop safety protocols and machine-tool manufacturer guidelines. Secure the shank fully in a precision collet or hydraulic tool holder to the holder's specified engagement depth before operation. Verify spindle speed and feed rate against the manufacturer's cutting data recommendations for the target workpiece material and coating class. Coolant-through is not supported on this tool; apply external flood or mist coolant as appropriate for the material being cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Width\u003c\/strong\u003e: 0.0200 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Angle\u003c\/strong\u003e: 45 degrees\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\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\u003eEnd Type\u003c\/strong\u003e: Single End, Center-Cutting\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing and Finishing\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 (PVD)\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, Superalloys and Titanium, Hard Material\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.84 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 4.33 inches length, 0.98 inches width, 0.98 inches height\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: 6677035\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51743369199922,"sku":"6677035","price":1403.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a2029abb8daa75b9ca2be3161c990bb4_3937cd49-cf1b-47d4-9549-cd98c9297b14.jpg?v=1788846265","url":"https:\/\/voomisupply.com\/products\/kennametal-6677035-corner-chamfer-end-mill-1in-4-flute-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
