With a 23\/64 inch (0.3594 inch) mill diameter and a 2-flute, right-hand spiral flute geometry at a 40-degree helix angle, it delivers efficient chip evacuation and clean edge finishes in a variety of cutting operations. The centercutting design allows plunge entry as well as conventional peripheral milling. Manufactured from micrograin solid carbide and supplied uncoated, this tool is suited for machinists and tool-and-die professionals who need consistent dimensional control in tight-tolerance work.\u003c\/p\u003e\u003cp\u003eThis end mill fits standard milling machine spindles and CNC machining centers that accept a 3\/8 inch shank. With a 7\/8 inch length of cut and a 2-1\/2 inch overall length, it is sized for regular-reach slotting, profiling, and contouring cuts. The right-hand cut and right-hand flute configuration is the conventional setup for most vertical milling operations. No extended reach or chipbreaker features are present, keeping the geometry straightforward for general-purpose material removal tasks in job shop and production environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCentercutting geometry allows both plunge and peripheral milling without a pre-drilled entry hole\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle promotes smooth chip flow and reduces cutting forces on the workpiece\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide construction provides rigidity and wear resistance in demanding cuts\u003c\/li\u003e\n\u003cli\u003eUncoated finish offers consistent performance and simplifies re-sharpening\u003c\/li\u003e\n\u003cli\u003eMill diameter tolerance of +0.000 \/ -0.002 inches supports close-tolerance slotting and profiling\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute — standard orientation for most milling setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement or standard tooling selection for milling machines and CNC machining centers with 3\/8 inch collet or end-mill holders.

Ensure the spindle is fully de-energized and locked out before changing tooling. Seat the shank fully in the collet or end-mill holder to the recommended engagement depth and torque the retention hardware per the toolholder manufacturer specifications. Verify runout with a dial indicator before beginning production cuts to confirm proper seating and avoid premature tool wear.\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 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 7\/8 inch (0.8750 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inch)\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\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: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003c\/strong\u003e: Uncoated\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\u003eExtended Reach\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\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\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: 12181398\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51754955997490,"sku":"12181398","price":57.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ff546bac943485e2cfd32afc9fba5ab5.jpg?v=1788950131","url":"https:\/\/voomisupply.com\/products\/accupro-12181398-square-end-mill-23-64-in-2-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
