With a 1\/2 inch cutting diameter and a 1-1\/4 inch length of cut, it handles slotting, profiling, and peripheral milling with consistent accuracy. The five-flute geometry paired with a 38-degree helix angle promotes efficient chip evacuation and smooth surface finishes at higher feed rates. An AlTiCrN coating provides thermal resistance and extended tool life when cutting hardened steels, stainless alloys, and other demanding workpiece materials. Machinists and CNC operators working in job shops, tool rooms, and production environments will find this end mill suited to demanding material removal tasks.\u003c\/p\u003e\u003cp\u003eThis end mill is built for use in vertical machining centers, CNC mills, and manual knee mills where a 1\/2 inch shank diameter is the standard tool holding size. Its single-end design and right-hand cutting direction make it compatible with conventional right-hand spindle setups. The variable index geometry helps reduce harmonic chatter during extended cuts, and the micrograin carbide substrate supports edge integrity in interrupted cuts and side-milling passes. It is suited to dry or minimal-quantity lubrication machining environments where AlTiCrN coatings perform at their best.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAlTiCrN coating for high thermal resistance and wear life in ferrous and hardened materials\u003c\/li\u003e\n\u003cli\u003eFive-flute spiral design increases material removal rate compared to standard four-flute tooling\u003c\/li\u003e\n\u003cli\u003e38-degree helix angle promotes smooth chip flow and reduces cutting forces\u003c\/li\u003e\n\u003cli\u003eVariable index flute spacing reduces chatter and vibration during long axial cuts\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate maintains sharp cutting edges at elevated temperatures\u003c\/li\u003e\n\u003cli\u003eCenter-cutting capable, allowing plunge entry directly into the workpiece\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit tool for CNC machining centers and manual mills accepting a 1\/2 inch shank diameter collet or end mill holder in the HS series configuration.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes must be performed with the machine spindle fully stopped and locked out per applicable safety procedures. Seat the 1\/2 inch shank fully and evenly in a precision collet or hydraulic holder to maintain runout within acceptable limits. Inspect the tool holder and collet bore for chips or debris before seating the end mill. Programmed feeds, speeds, and depth of cut should be set based on workpiece material hardness and machine rigidity before initiating a cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5000 inches (12.70 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.2500 inches (31.75 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 38 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: AlTiCrN\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\u003eVariable Helix\u003c\/strong\u003e: No\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\u003eSeries\u003c\/strong\u003e: HS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 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: 311634\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51727661203762,"sku":"311634","price":115.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e6f35ff98868ff8f435ff42493e90647.jpg?v=1788680688","url":"https:\/\/voomisupply.com\/products\/accupro-311634-square-end-mill-1-2-in-5-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
