With a 3\/8 inch mill diameter and 4 variable-helix flutes, this single-end tool handles both roughing and finishing operations. The 45-degree chamfer angle and 0.0200 inch chamfer width produce clean, consistent edge breaks and chamfers in a single pass. An AlTiN (aluminum titanium nitride) PVD coating extends tool life at elevated cutting temperatures, making this end mill well suited to dry or minimal-lubrication cutting. It is used by machinists and tool-and-die professionals in job shops, production machining cells, and aerospace component manufacturing.\u003c\/p\u003e\u003cp\u003eThis end mill fits applications including shouldering, slotting, ramp-down entry, helical interpolation, drill milling, and plunging and recessing. Its right-hand cut and right-hand flute direction are compatible with standard CNC milling center spindles. The variable helix and variable index geometry help reduce chatter and harmonic vibration during aggressive cuts. Primary workpiece materials include steel, stainless steel, cast iron, superalloys and titanium, and hard materials, covering a broad range of production and toolroom work. The straight-cylindrical shank and 3\/8 inch shank diameter allow direct clamping in standard collet chucks or end mill holders without adapters.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e45-degree chamfer angle with 0.0200 inch chamfer width for consistent edge preparation\u003c\/li\u003e\n\u003cli\u003eVariable helix and variable index flute geometry reduces vibration and chatter\u003c\/li\u003e\n\u003cli\u003eAlTiN PVD coating provides thermal resistance for dry and semi-dry cutting\u003c\/li\u003e\n\u003cli\u003eCentercutting design enables plunging and helical interpolation entry moves\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction (material grade KCPM15) for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eSuitable for both roughing and finishing in a single tool\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with steel, stainless steel, cast iron, superalloys and titanium, and hard materials.

Power down and lock out the spindle before loading or changing the end mill. Seat the straight-cylindrical shank fully into the collet or end mill holder and torque the retention hardware per the toolholder manufacturer specification. Verify runout with a dial indicator before beginning production cuts; excessive runout accelerates wear and reduces chamfer accuracy.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1\/2 inch (0.5000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 1\/2 inch (0.5000 inches)\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\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Style\u003c\/strong\u003e: Variable (36 to 39 degrees)\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 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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Normal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\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\u003ePackage Dimensions\u003c\/strong\u003e: 4.33 inches L x 0.98 inches W x 0.98 inches H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.09 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: 6676998\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51743265980722,"sku":"6676998","price":154.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a2029abb8daa75b9ca2be3161c990bb4_d447a347-fe11-48ce-a793-5fdf08b7bbfd.jpg?v=1788844726","url":"https:\/\/voomisupply.com\/products\/kennametal-6676998-corner-chamfer-end-mill-3-8-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
