With a 0.375 inch mill diameter and a 1.75 inch length of cut, it delivers controlled material removal across a range of ferrous and non-ferrous workpieces. The 2-flute configuration promotes chip evacuation, and the nACRo coating provides enhanced wear resistance at elevated cutting temperatures. The 40-degree helix angle improves cutting action and surface finish. Machinists and CNC operators in production and job shop settings are the primary users of this tool.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for slotting, profiling, and plunging operations where centercutting capability is required. The right-hand cut and right-hand spiral flute geometry are standard for conventional and climb milling on vertical and horizontal machining centers. A 3\/8 inch shank diameter and 4 inch overall length make it compatible with standard collet and end mill holder setups on a wide range of CNC and manual mills.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction with micrograin material grade for rigidity and edge retention\u003c\/li\u003e\n\u003cli\u003enACRo finish coating for improved heat and wear resistance\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle for smooth cutting action and improved surface finish\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry into the workpiece\u003c\/li\u003e\n\u003cli\u003e2-flute spiral geometry promotes chip clearance in slotting and full-width cuts\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute for standard milling machine setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard 3\/8 inch collets and end mill holders on CNC machining centers and manual knee mills requiring a square-end, 2-flute solid carbide tool with a 3\/8 inch shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and locked out before tool changes. Seat the shank fully into the collet or holder and torque the retention hardware per the toolholder manufacturer specifications. Confirm runout with a dial indicator before engaging a cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.375 inches (3\/8 inch)\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: 1.75 inches (1-3\/4 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut Range\u003c\/strong\u003e: 1.5 to 2.0 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches (3\/8 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\u003eOverall Length\u003c\/strong\u003e: 4.0 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\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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide, Micrograin Grade\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: nACRo\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 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: 12178831\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":67948714361138,"sku":"12178831","price":123.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/46bcc4cfdfc6fe3194150145a6b0a345.jpg?v=1791670599","url":"https:\/\/voomisupply.com\/products\/accupro-12178831-square-end-mill-3-8-in-2-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
