With a 0.2500 inch mill diameter and 6 helical flutes, it delivers efficient material removal and superior surface finish in high-temperature alloys and similarly difficult workpiece materials. The AlTiN+ coating provides enhanced heat resistance and wear protection at elevated cutting temperatures. The variable helix angle of 36 and 40 degrees reduces harmonic vibration during cuts, extending tool life and improving finish quality. This end mill is center-cutting, allowing plunge entry, and features a right-hand cutting and flute direction with a straight shank. It is intended for use by machinists and CNC tooling professionals.\u003c\/p\u003e\n\u003cp\u003eThis ball end mill is suited for profiling, contouring, and finishing operations in high-temp alloys including nickel-based and titanium alloys, corresponding to ISO material group S. Its 1.0000 inch length of cut and 3.0000 inch overall length make it appropriate for moderate-depth cavity work and 3D surface milling. The single-end design and straight shank with 0.2500 inch diameter allow direct chuck or collet mounting in standard CNC machining centers and manual mills. No coolant-through capability is present, so external coolant or air blast is recommended when cutting heat-resistant materials.\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 provides oxidation resistance and extends tool life in high-temp alloy cutting\u003c\/li\u003e\n  \u003cli\u003eVariable helix at 36 and 40 degrees reduces chatter and harmonic vibration\u003c\/li\u003e\n  \u003cli\u003eVariable index geometry improves surface finish and tool stability\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting design allows direct plunge milling without a pre-drilled entry point\u003c\/li\u003e\n  \u003cli\u003e6-flute configuration increases feed rate capability compared to 4-flute tools of the same diameter\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard CNC machining centers and manual mills accepting a 0.2500 inch straight shank via collet or end mill holder.

Ensure the spindle is fully stopped and the machine is powered down or in a safe-stop state before changing tooling. Seat the straight shank fully into the collet or holder before torquing to the equipment manufacturer's specification. Confirm runout with a dial indicator before beginning a production cut, as even minor runout significantly affects tool life in carbide end mills.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.2500 inches (6.35 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: 1.0000 inches (25.40 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.0000 inches (76.20 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2500 inches (6.35 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\u003c\/strong\u003e: AlTiN+\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\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\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\u003eCenter Cutting\u003c\/strong\u003e: Yes\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\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: 0.07 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: 72054380\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51744594329906,"sku":"72054380","price":85.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1387a1cbc85e69f037e155e448d18e22_67d17145-3fe5-4a60-991d-4a5d0b14222e.jpg?v=1788858766","url":"https:\/\/voomisupply.com\/products\/accupro-72054380-ball-end-mill-1-4-inch-6-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
