With a 3\/8 inch (0.3750 inch) mill diameter and 6 helical flutes, it delivers smooth chip evacuation and consistent surface finishes in difficult-to-machine workpiece materials. The AlTiN+ coating provides thermal and oxidation resistance critical when cutting nickel-based alloys, titanium, and similar aerospace-grade materials. The variable helix and variable index geometry reduce harmonic vibration during cutting, improving tool life and finish quality. This is a single-end, center-cutting tool intended for use by machinists in production and job shop environments on CNC machining centers and mills.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for roughing and finishing operations in high-temp alloy applications, identified under material code S. The 1.5 inch length of cut and 3.5 inch overall length make it well suited for moderate-depth cavity, slot, and contour milling. The straight shank with a 3\/8 inch shank diameter fits standard ER and other common toolholders. Its right-hand cutting and right-hand flute direction are standard for conventional CNC milling setups. The tool carries no chipbreaker and does not support coolant-through delivery, so flood or mist coolant applied externally is the appropriate cooling method for this geometry.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003eAlTiN+ coating for high-heat resistance when machining high-temperature alloys\u003c\/li\u003e\n  \u003cli\u003e6-flute variable helix (36 and 40 degrees) with variable index to suppress chatter and improve finish\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting geometry allows plunge entry directly into the workpiece\u003c\/li\u003e\n  \u003cli\u003e1.5 inch length of cut with 3.5 inch overall length for moderate-depth applications\u003c\/li\u003e\n  \u003cli\u003eSingle-end design; right-hand cut and right-hand helix for standard CNC use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard 3\/8 inch straight-shank toolholders on CNC machining centers and mills. Primary workpiece material designation is high-temp alloy (material code S), including nickel-based superalloys and titanium. Specific machine or holder compatibility should be confirmed against the toolholder manufacturer specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and tool changes should be performed by a qualified machinist with the spindle fully stopped and machine power isolated per shop lockout\/tagout procedures. Ensure the shank is fully seated and properly torqued in the toolholder to the holder manufacturer specification before operation. Verify runout with a dial indicator before commencing a cut, as excessive runout will accelerate wear on this multi-flute geometry. External flood or mist coolant is recommended since this tool does not support coolant-through delivery.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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\u003eMill Diameter (mm)\u003c\/strong\u003e: 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\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\u003eLength of Cut\u003c\/strong\u003e: 1.5000 inches (38.10 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.5000 inches (88.90 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inches \/ 9.53 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Helical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 36 and 40 degrees (Variable)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: Yes\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\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\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 (Code: S)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Fractional Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.18 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 72035272\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51737886818610,"sku":"72035272","price":97.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1387a1cbc85e69f037e155e448d18e22_dfe72607-a630-4112-88e1-5060e3b1928f.jpg?v=1788794862","url":"https:\/\/voomisupply.com\/products\/accupro-72035272-ball-end-mill-3-8-inch-6-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
