Built on the H1TE series platform, it features a 0.5-inch mill diameter, 1-inch length of cut, and a 45-degree chamfer angle with a 0.02-inch chamfer width. The 4-flute, variable-helix geometry (36 to 39 degrees) reduces chatter and supports both roughing and finishing in a single tool. An AlTiN PVD coating improves heat resistance and extends tool life at elevated cutting speeds. This end mill is center-cutting and designed for single-end use by skilled machinists and CNC operators in production and job-shop settings.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for machining steel, stainless steel, cast iron, superalloys, titanium, and hard materials. Its variable-helix, variable-index flute design supports shouldering, slotting, ramp-down entry, helical interpolation, drill milling, and plunging and recessing operations. The straight-cylindrical shank measures 0.5 inches in diameter with a 3-inch overall length, making it compatible with standard ER and side-lock toolholders commonly found on vertical and horizontal machining centers.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eVariable helix (36 to 39 degrees) and variable index flutes reduce vibration and improve surface finish\u003c\/li\u003e\n\u003cli\u003e45-degree chamfer angle with 0.02-inch chamfer width for precise edge breaking and chamfering\u003c\/li\u003e\n\u003cli\u003eAlTiN PVD coating provides high oxidation resistance for cutting steel, stainless, and hard materials\u003c\/li\u003e\n\u003cli\u003eCenter-cutting geometry supports plunging, ramp-down, and helical interpolation\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction in material grade KCPM15 for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eSupports multiple operations: shouldering, slotting, drill milling, and recessing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and production end mill for machining centers running steel, stainless steel, cast iron, superalloys, titanium, and hard materials.

Secure the straight-cylindrical shank in a clean, properly sized collet or toolholder and torque to the toolholder manufacturer specification before running. Inspect the cutting edges and coating for chips or damage before each use. Do not exceed the tool manufacturer recommended feeds and speeds for the workpiece material being cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Width\u003c\/strong\u003e: 0.02 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\u003eCoating\u003c\/strong\u003e: AlTiN (PVD)\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\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter Cutting\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\u003eSeries\u003c\/strong\u003e: H1TE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 4.33 x 0.98 x 0.98 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.24 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: 6677002\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51740301197618,"sku":"6677002","price":266.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a2029abb8daa75b9ca2be3161c990bb4_35cf328c-ae18-42f3-b6ba-4e1d04df3914.jpg?v=1788824129","url":"https:\/\/voomisupply.com\/products\/kennametal-6677002-corner-chamfer-end-mill-1-2-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
