Built on the H1TE series platform, it features a 6 mm cutting diameter, a 0.5 mm corner radius, and a 13 mm length of cut. The AlTiN PVD coating provides thermal resistance and wear protection, making this tool effective at elevated cutting temperatures common in hard material and superalloy machining. Four right-hand helical flutes at a 36-degree helix angle promote efficient chip evacuation while maintaining a smooth surface finish. Centercutting geometry allows plunge entry without a pre-drilled pilot hole.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for both roughing and finishing operations on steel, stainless steel, cast iron, superalloys, titanium, and hard materials. The extended reach design, with a 31.98 mm reach length and a reduced 5.64 mm neck diameter, allows access to deeper features and pockets without sacrificing rigidity at the shank. It is intended for use in CNC machining centers and mill-turn platforms where tight tolerances and consistent tool life are required. Compatible with ER single angle standard collets for toolholding.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide submicron-grade construction for wear resistance in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003eAlTiN PVD coating provides oxidation resistance and extended tool life at high cutting temperatures\u003c\/li\u003e\n\u003cli\u003e0.5 mm corner radius reduces stress concentration and improves edge strength compared to sharp-corner geometry\u003c\/li\u003e\n\u003cli\u003eExtended reach with 31.98 mm reach length and 5.64 mm neck diameter for deep-pocket access\u003c\/li\u003e\n\u003cli\u003eCentercutting capable for direct plunge milling without pre-drilling\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute, normal pitch configuration suitable for conventional CNC milling setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with ER single angle standard collets.

Part of the KENNAMETAL H1TE series; catalog reference H1TE4RA0600E013HAR050M.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC setup technician. Secure the shank fully within the collet to the recommended engagement depth before tightening to avoid runout. Verify spindle speed, feed rate, and depth of cut against the applicable KENNAMETAL H1TE series cutting data before first use. Inspect the cutting edges and coating condition before each use and replace the tool at the first sign of chipping or excessive flank wear.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 6 mm (0.2362 inches)\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: 13 mm (1.25 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 70 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 5.64 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 31.98 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 (Submicron Grade)\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\u003eEnd Type\u003c\/strong\u003e: Corner Radius\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\u003eSingle or Double End\u003c\/strong\u003e: Single\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\u003eSeries\u003c\/strong\u003e: H1TE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 5.12 inches L x 1.19 inches W x 1.19 inches H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 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: 6929439\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51746544124210,"sku":"6929439","price":160.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/795d204c19b5123fbf70348d4b7c4ad8_be588fe7-5454-4be6-8645-a2f46918f6de.jpg?v=1788871158","url":"https:\/\/voomisupply.com\/products\/kennametal-6929439-corner-radius-end-mill-6mm-4-flute-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
