It features a 3\/4 inch diameter cutting profile with five flutes and a 2-1\/4 inch length of cut, making it suited for deeper slot, profile, and peripheral milling passes. The micrograin carbide substrate provides hardness and edge retention under demanding cutting conditions. The 36-degree helix angle promotes efficient chip evacuation, and a variable index geometry combined with integrated chipbreakers reduces chatter and vibration during aggressive cuts. This tool is sold individually and handled by skilled machinists and CNC programmers in shop environments.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for use in vertical machining centers, CNC mills, and manual knee mills where a 3\/4 inch straight-cylindrical shank is the standard holder interface. The bright, uncoated finish makes it a solid choice for applications where coating interaction with the workpiece material is a concern, or where regrinding and reuse are part of the shop's tooling program. The Series AL-5 designation indicates it is part of ACCUPRO's extended-length carbide end mill lineup, suited for reaching into pockets and cavities that shorter tools cannot access. A right-hand cut and right-hand flute direction are standard for conventional CNC spindle rotation.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5-flute geometry increases feed rate potential compared to 4-flute designs in stable setups\u003c\/li\u003e\n\u003cli\u003eVariable index flute spacing reduces harmonic chatter and vibration during deep cuts\u003c\/li\u003e\n\u003cli\u003eChipbreaker geometry assists chip control in long-reach slot milling and pocketing operations\u003c\/li\u003e\n\u003cli\u003e36-degree helix angle promotes upward chip flow and reduces heat buildup at the cutting edge\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate delivers edge strength and dimensional consistency across the tool life\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish supports regrinding and suits applications where coatings are undesirable\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement for 3\/4 inch straight-cylindrical shank tool holders including ER collet chucks, hydraulic holders, and shrink-fit systems accepting a 0.75 inch shank diameter.

Ensure the machine spindle is fully stopped and the tool changer or spindle lock is engaged before mounting or removing the tool. Confirm runout with a dial indicator after seating to verify the shank is fully engaged in the holder. Follow shop safety protocols and machine manufacturer guidelines for speeds, feeds, and depth-of-cut parameters appropriate to the workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/4 inches (0.7500 inches)\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\u003eNumber of Flutes\u003c\/strong\u003e: 5\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\u003eLength of Cut\u003c\/strong\u003e: 2-1\/4 inches (2.25 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/4 inches (0.75 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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 36 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\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\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\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating \/ Finish\u003c\/strong\u003e: Bright \/ Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: AL-5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.98 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: 14777965\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51738083131698,"sku":"14777965","price":280.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/653d1b1f813261ec352be5d85924d597.jpg?v=1788796059","url":"https:\/\/voomisupply.com\/products\/accupro-14777965-square-end-mill-3-4-in-5-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
