Built on the H1TE series platform, it features a 0.25-inch mill diameter, a 0.03-inch corner radius, and an AlTiN (aluminum titanium nitride) PVD coating that extends tool life in high-heat cutting environments. With 4 right-hand spiral flutes and a centercutting design, this end mill handles both roughing and finishing passes. The submicron carbide grade provides the hardness and wear resistance needed when working in difficult-to-machine materials. It is installed by machinists and CNC operators in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for milling steel, stainless steel, cast iron, superalloys, titanium, and hard materials. The 3\/4-inch length of cut and 2.5-inch overall length make it a compact, rigid choice for slotting, profiling, and contouring operations where tool deflection must be minimized. The straight-cylindrical shank accepts standard collet chucks and hydraulic tool holders. Kennametal specifies compatibility with HC 20M through HC 32M hydraulic sleeves metric with inch bores and HC-CV Form AD tool holders.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAlTiN PVD coating improves heat resistance and extends tool life in ferrous and hard-material cutting\u003c\/li\u003e\n\u003cli\u003eSolid submicron carbide construction delivers edge stability during both roughing and finishing operations\u003c\/li\u003e\n\u003cli\u003e0.03-inch corner radius reduces stress concentration at the cutting edge and improves surface finish on corners\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows direct plunge entry into the workpiece\u003c\/li\u003e\n\u003cli\u003eRight-hand flute direction and normal pitch for consistent chip evacuation in standard milling operations\u003c\/li\u003e\n\u003cli\u003eNo coolant-through requirement simplifies setup in shops without high-pressure coolant systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with HC 20M through HC 32M hydraulic sleeves metric with inch bores and HC-CV Form AD tool holders.

The machine spindle must be fully stopped and the tool holder must be depressurized or released before inserting or removing the end mill. Verify runout after clamping to confirm proper seating in the collet or hydraulic holder. Do not exceed the tool manufacturer's recommended cutting parameters for the specific workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.03 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 0.7402 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 36 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\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\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing and Finishing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Superalloys, Titanium, Hard Material\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: H1TE\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\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: 6676371\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51739463647538,"sku":"6676371","price":99.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/07a49ed9e00b7aa9b89cab4141d7a4b9_427014f7-6ee2-41e5-abe4-132d566d7f56.jpg?v=1788814874","url":"https:\/\/voomisupply.com\/products\/kennametal-6676371-corner-radius-end-mill-0-25in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
