At 0.375 inches in diameter with a 0.015-inch corner radius, this single-end mill features a variable helix and variable index geometry that reduces harmonic vibration and chatter during deep cuts. The AlTiN+ coating provides thermal resistance and extended tool life in demanding milling applications. Overall length is 3.0 inches with a length of cut of 1.25 inches. It is centercutting and configured for right-hand cutting and right-hand flute direction.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for precision slot milling, peripheral milling, and contour work in high-temp alloys including nickel-based superalloys and titanium-group materials, categorized under ISO material code S. It is a single-end tool intended for use in machining centers and CNC milling setups where tight tolerances and surface finish are critical. The 3\/8-inch shank diameter is compatible with standard ER collet chucks, end mill holders, and hydraulic toolholders of the same bore size.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eVariable helix and variable index geometry reduce chatter and improve surface finish in hard materials\u003c\/li\u003e\n\u003cli\u003eAlTiN+ coating delivers high thermal and oxidation resistance for dry or near-dry cutting of high-temp alloys\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction provides rigidity and wear resistance compared to HSS equivalents\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows plunge entry and ramping operations\u003c\/li\u003e\n\u003cli\u003e0.015-inch corner radius protects the cutting edge and reduces corner chipping under load\u003c\/li\u003e\n\u003cli\u003e6-flute configuration increases feed rate capability while maintaining chip clearance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC machining centers with standard 3\/8-inch bore toolholding systems.

Ensure the tool shank is fully seated and secured in the toolholder to the manufacturer-specified engagement depth before running the spindle. Verify spindle orientation and programmed cutting direction match the right-hand configuration of this tool before initiating a cut. Inspect the cutting edges and coating condition before each use; do not run a chipped or worn carbide tool at full parameters.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.375 inches (9.53 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.25 inches (31.75 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.0 inches (76.2 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches (9.53 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.015 inches (0.38 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: AlTiN+\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\u003eHelix Style\u003c\/strong\u003e: Variable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: High-Temp Alloy (ISO Code S)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.14 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: ACCUPRO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 72016744\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51728946659634,"sku":"72016744","price":100.27,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1387a1cbc85e69f037e155e448d18e22_5db4d5ea-82b8-4f0b-b633-041fef56b5cb.jpg?v=1788697933","url":"https:\/\/voomisupply.com\/products\/accupro-72016744-corner-radius-end-mill-3-8-in-6-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
