With a 23\/64 inch (0.3594 inch) mill diameter, a 7\/8 inch length of cut, and a 3\/8 inch shank diameter, this tool delivers tight tolerances and reliable stock removal. The TiCN (Titanium Carbonitride) coating increases surface hardness and wear resistance, extending tool life in demanding cuts. Three spiral flutes with a 40-degree helix angle improve chip evacuation and reduce cutting forces. The micrograin carbide substrate supports higher cutting speeds and feeds compared to standard carbide grades.\u003c\/p\u003e\u003cp\u003eThis end mill suits general-purpose milling operations including slotting, profiling, and peripheral cuts on ferrous and non-ferrous metals. The centercutting design allows plunge entry, making it practical for pocketing and ramp entry without a pre-drilled hole. The right-hand cut and right-hand flute geometry are standard for conventional CNC machining centers and manual mills. The 2-1\/2 inch overall length and regular length classification fit most standard toolholders and collet chucks without requiring extended-reach setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e23\/64 inch mill diameter with mill diameter tolerance of +0.000\/-0.002 inches for consistent fit\u003c\/li\u003e\n\u003cli\u003eSolid micrograin carbide construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eTiCN coating for improved hardness and reduced tool wear in steel and cast iron\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle spiral flutes for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCentercutting design enables direct plunge entry\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute, compatible with standard CNC and manual mill setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard 3\/8 inch collet chucks, ER collet systems, and toolholders accepting a 3\/8 inch straight shank.

Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before installing or removing tooling. Clean the collet bore and shank of debris before seating the tool to maintain runout tolerances. Verify shank engagement depth meets toolholder manufacturer specifications before beginning a cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 23\/64 inch (0.3594 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\u003eLength of Cut\u003c\/strong\u003e: 7\/8 inch (0.875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch (0.375 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\u003eOverall Length\u003c\/strong\u003e: 2-1\/2 inches (2.5 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 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: TiCN\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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\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\u003eVariable Index\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\u003eWeight\u003c\/strong\u003e: 0.12 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: 12182011\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51729350295858,"sku":"12182011","price":75.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/77797b4b542577f52a2f647d996e4059.jpg?v=1788703338","url":"https:\/\/voomisupply.com\/products\/accupro-12182011-square-end-mill-23-64-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
