The cutter measures 16 mm in diameter with a 0.5 mm corner radius and a 24 mm length of cut. Four right-hand spiral flutes and a 36-degree helix angle deliver efficient chip evacuation across both roughing and finishing operations. An AlTiN PVD coating provides thermal resistance and extended tool life in high-heat cutting environments. The straight cylindrical shank matches the cutter diameter at 16 mm, making it compatible with standard hydraulic and collet toolholders. Licensed machinists and CNC programmers working in production shops specify this series for its submicron carbide grade and consistent performance in short-flute configurations.\u003c\/p\u003e\n\u003cp\u003eThe 6676277 belongs to the Kennametal H1TE series, which targets short-flute, extended-reach applications on vertical and horizontal machining centers. The 100 mm overall length with a 48.46 mm reach length and a 15.04 mm neck diameter allows clearance in deeper pockets while keeping the cutting zone close to the holder for rigidity. This centercutting geometry supports plunge entry and full-slot milling. Typical applications include contour milling, profile finishing, and semi-finish passes on hardened components and near-net-shape aerospace or die-and-mold workpieces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e16 mm cutting diameter with 0.5 mm corner radius for blend radii and edge protection\u003c\/li\u003e\n  \u003cli\u003eAlTiN PVD coating rated for steel, stainless steel, cast iron, superalloys, titanium, and hard materials\u003c\/li\u003e\n  \u003cli\u003eSubmicron solid carbide grade for wear resistance in abrasive and high-hardness workpieces\u003c\/li\u003e\n  \u003cli\u003e36-degree right-hand spiral flutes with normal pitch for balanced chip load and surface finish\u003c\/li\u003e\n  \u003cli\u003eExtended-reach design with 48.46 mm reach length and reduced 15.04 mm neck diameter for deep-feature access\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows direct plunge entry without pre-drilling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with HC 1\/2 to HC 1-1\/4 hydraulic sleeves inch with metric bores and ER single angle standard collets.

Confirm holder bore size matches the 16 mm shank before tightening to prevent runout and premature tool failure. Do not exceed the toolholder manufacturer's recommended clamping torque for the holder type in use. Inspect the corner radius and cutting edges for chipping or coating wear before each setup.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 16 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.5 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: 24 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 100 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 16 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 15.04 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 48.46 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 36 degrees\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: Submicron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN PVD\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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Normal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Short\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\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\u003eChipbreaker\u003c\/strong\u003e: No\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Superalloys and Titanium, Hard Material\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: H1TE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.51 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: 6676277\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51728071328050,"sku":"6676277","price":369.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/470ba5087d981100cb058be1e64a2fa7.jpg?v=1788687402","url":"https:\/\/voomisupply.com\/products\/kennametal-6676277-corner-radius-end-mill-16mm-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
