It features a 1\/4-inch cutting diameter, a 3\/8-inch length of cut, and a 38-degree helix angle that promotes efficient chip evacuation and smooth cutting action. The AlTiCrN coating provides enhanced heat and wear resistance, making this end mill well suited for high-speed cutting in hardened steels, stainless steel, and other demanding alloys. This is a single-end, right-hand cutting tool from the HS Series, ground from micrograin carbide substrate for edge consistency. Machinists and CNC operators in job shops and production environments are the primary users.\u003c\/p\u003e\u003cp\u003eThis end mill is applied in vertical and horizontal milling centers as well as manual knee mills where a 1\/4-inch shank is accepted. The four-flute, variable-index geometry supports both roughing and finishing passes in ferrous and non-ferrous materials. The single-end configuration means the tool is replaced rather than reindexed when worn. It is particularly well matched to applications requiring tight tolerances in shallow-to-moderate depth-of-cut passes where rigidity and surface finish are priorities.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for rigidity and edge retention\u003c\/li\u003e\n\u003cli\u003eAlTiCrN coating for high-temperature wear resistance in ferrous and hardened materials\u003c\/li\u003e\n\u003cli\u003e38-degree helix angle promotes efficient chip evacuation and reduced cutting forces\u003c\/li\u003e\n\u003cli\u003eVariable index flute spacing reduces harmonic chatter during cutting\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting, centercutting design allows plunge entry\u003c\/li\u003e\n\u003cli\u003e1\/4-inch shank diameter matches 1\/4-inch collet and end mill holders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use end mill for CNC machining centers and manual milling machines accepting a 1\/4-inch shank collet or end mill holder.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists using an appropriate collet chuck or end mill holder rated for the 1\/4-inch shank diameter. Ensure the machine spindle is fully stopped and locked out before changing tooling. Confirm runout with a dial indicator after seating to maintain dimensional accuracy. Follow machine manufacturer torque specifications for drawbar or collet nut tightening.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.250 inches (6.35 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.250 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.375 inches (9.53 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 2 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: 38 degrees\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\u003eEnd Type\u003c\/strong\u003e: Single End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\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\u003eVariable Helix\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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiCrN\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: 0.02 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: ACCUPRO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 310074\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51731635765554,"sku":"310074","price":48.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5acf5d1d889a5631dd5c3ad259d6e82f.jpg?v=1788733414","url":"https:\/\/voomisupply.com\/products\/accupro-310074-square-end-mill-1-4-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
