It carries a 5\/8 inch diameter with a 1-1\/4 inch length of cut and a 3-1\/2 inch overall length, making it well suited for regular-reach applications. The 45-degree chamfer angle and 0.0200 inch chamfer width produce clean, consistent edge breaks on finish and semi-finish passes. An AlTiN PVD coating provides thermal resistance and wear protection at elevated cutting speeds. Variable helix and variable index geometry reduce chatter and harmonic vibration during aggressive cuts. This tool is centercutting and handles both roughing and finishing operations. It is installed by machinists and CNC tooling specialists in shop and production settings.\u003c\/p\u003e\u003cp\u003eThe 6677006 is built for machining steel, stainless steel, cast iron, superalloys, and titanium, as well as hard materials. It supports shouldering, slotting, ramp-down entry, helical interpolation, drill mill operations, and plunging and recessing. The single-end, straight-cylindrical shank at 5\/8 inch diameter fits standard ER and side-lock toolholders common in vertical and horizontal machining centers. The right-hand cut and right-hand flute direction are standard for conventional CNC spindle rotation. Material grade KCPM15 and the H1TE series designation identify the substrate and geometry family within the KENNAMETAL line.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e45-degree chamfer angle with 0.0200 inch chamfer width for precise edge breaking\u003c\/li\u003e\n\u003cli\u003eAlTiN PVD coating for high-temperature wear resistance on ferrous and hard materials\u003c\/li\u003e\n\u003cli\u003eVariable helix and variable index flute geometry to minimize vibration and chatter\u003c\/li\u003e\n\u003cli\u003eCentercutting design enables plunging, ramp-down, and helical interpolation entry\u003c\/li\u003e\n\u003cli\u003eSupports roughing and finishing in a single tool across multiple operation types\u003c\/li\u003e\n\u003cli\u003eSolid carbide KCPM15 substrate for rigidity and edge stability in difficult-to-machine alloys\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard CNC machining centers with 5\/8 inch straight-cylindrical shank toolholders.

Ensure the machine spindle is fully stopped and the tool path program is cleared before changing tooling. Secure the straight-cylindrical shank to the specified clamping torque of the toolholder manufacturer and verify runout with a dial indicator before production cuts. Coolant-through is not supported on this tool; apply external flood or mist coolant as required by the workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.6250 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.2500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.5000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.6250 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\u003eSeries\u003c\/strong\u003e: H1TE\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\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: 0.42 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: 6677006\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51740646015282,"sku":"6677006","price":477.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a2029abb8daa75b9ca2be3161c990bb4_4761cc60-ec2c-4382-8e55-c60481f52489.jpg?v=1788826443","url":"https:\/\/voomisupply.com\/products\/kennametal-6677006-corner-chamfer-end-mill-5-8in-4-flute-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
