With a 0.3937 inch (10 mm) mill diameter and a 40-degree helix angle, it delivers aggressive chip evacuation and smooth cutting action. The 2-flute geometry with TiCN (Titanium Carbonitride) coating provides improved wear resistance and surface hardness over uncoated carbide. The micrograin carbide substrate supports tight tolerances and fine finishes on demanding materials. This is a centercutting tool, meaning it can plunge directly into a workpiece as well as perform peripheral and slot milling operations. It is installed and run by machinists and CNC operators in precision manufacturing environments.\u003c\/p\u003e\n\u003cp\u003eThis end mill suits applications in general-purpose machining, die and mold work, and production milling where close dimensional tolerances are required. The regular-length profile and 0.9843 inch (25 mm) length of cut make it well suited for shallow-to-moderate depth slot milling, profiling, and contouring passes. Right-hand cut and right-hand flute configuration is standard for conventional spindle setups. The spiral flute design promotes consistent chip flow away from the cutting zone, reducing recutting and heat buildup during continuous passes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTiCN coating for increased surface hardness and wear resistance compared to uncoated carbide\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle promotes efficient chip evacuation and reduces cutting forces\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge entry into workpiece material\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide substrate for tight tolerances and extended tool life\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand spiral flute for use with standard CNC and manual mill spindles\u003c\/li\u003e\n  \u003cli\u003eNo chipbreaker, variable helix, or variable index  -  straightforward geometry for consistent, repeatable results\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard straight-shank square end mill compatible with collet chucks, end mill holders, and shrink-fit toolholders accepting a 10 mm (0.3937 inch) shank diameter. Verify holder tolerance range against shank diameter tolerance of -0.0001 to -0.0004 inches before installation.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall in a clean, properly sized collet or toolholder and torque to the toolholder manufacturer's specification. Ensure the shank is fully seated to the recommended insertion depth before securing. Verify spindle runout is within acceptable limits prior to cutting  -  excessive runout accelerates edge wear on carbide tooling. Follow shop-specific feeds and speeds protocols and machine parameter sheets for TiCN-coated carbide end mills.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.3937 inches (10 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.9843 inches (25 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-3\/4 inches (70 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 10 mm\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\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\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\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: 12181434\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51741292134706,"sku":"12181434","price":92.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/10d9729822f47dda471bdca0bee3216b.jpg?v=1788830581","url":"https:\/\/voomisupply.com\/products\/accupro-12181434-square-end-mill-0-3937-in-2-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
