Built from micrograin carbide and finished with an AlTiN coating, it handles demanding cuts in ferrous and hardened materials where heat resistance and edge retention matter. The 1\/4 inch diameter tool features 4 flutes with a variable helix geometry that reduces harmonic vibration and improves chip evacuation during aggressive cutting passes. With a 3\/8 inch length of cut and 2 inch overall length, this stub-length design provides rigidity in tight-clearance setups. Installation and use are performed by machinists and CNC operators in job shop or production environments.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for milling slots, profiles, and pockets in steel, stainless steel, cast iron, and similar hard materials. The variable helix flute geometry helps minimize chatter on longer cuts and in thin-wall workpiece scenarios. The stub-length configuration keeps deflection low, making it a practical choice for high-feed or high-speed machining strategies on vertical and horizontal CNC machining centers as well as manual knee mills. Right-hand cutting and right-hand flute direction are standard for conventional spindle setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for superior wear resistance and edge sharpness\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating improves heat resistance and extends tool life in ferrous materials\u003c\/li\u003e\n  \u003cli\u003eVariable helix flutes reduce vibration and chatter during aggressive milling\u003c\/li\u003e\n  \u003cli\u003e4 flutes with spiral flute type for efficient chip removal\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows plunge entry into workpieces\u003c\/li\u003e\n  \u003cli\u003eStub length of cut provides added rigidity in close-clearance applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard-fitment cutting tool compatible with 1\/4 inch straight shank tool holders, collet chucks, and ER-style collets used on CNC and manual milling machines.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a machinist or CNC operator. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the 1\/4 inch shank fully into the collet or tool holder and torque the retention nut to the tool holder manufacturer specification. Inspect the cutting edges for chips or damage before each use, and verify runout with a dial indicator when tolerances are critical.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/4 inch (0.2500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide, Micrograin Grade\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3\/8 inch (0.375 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/4 inch (0.2500 inches)\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: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\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\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 \/ -0.002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: +0.0001 \/ -0.0004 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.75 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: 95168254\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51742483841330,"sku":"95168254","price":67.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7193b3a0db8f40c355c2d2a1df5ad9ec.jpg?v=1788837741","url":"https:\/\/voomisupply.com\/products\/accupro-95168254-square-end-mill-1-4-in-4-flute-carbide-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
