It measures 0.375 inches in cutting diameter with a 0.625-inch length of cut and a 2-inch overall length. The micrograin carbide construction provides the hardness and edge retention needed for demanding cuts in ferrous and non-ferrous materials. A 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. This tool is intended for use by machinists and CNC operators working on mills, machining centers, and similar equipment.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for stub-length milling applications where rigidity is a priority and deflection must be minimized. The three-flute, right-hand cut and right-hand spiral flute configuration is commonly used for general-purpose slotting, profiling, and peripheral milling. The centercutting geometry allows for plunge cuts into the workpiece. Uncoated carbide is appropriate for a range of base materials and is a practical choice when regrinding is expected.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for hardness and wear resistance\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle for efficient chip evacuation and reduced cutting forces\u003c\/li\u003e\n\u003cli\u003eThree flutes with right-hand cut and right-hand spiral for general-purpose milling\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry into the workpiece\u003c\/li\u003e\n\u003cli\u003eStub length provides added rigidity and reduced deflection\u003c\/li\u003e\n\u003cli\u003eUncoated finish suitable for standard machining and regrinding applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard tooling selection for CNC machining centers and manual milling machines accepting a 3\/8-inch straight shank end mill.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator. Secure the shank firmly in a collet or end mill holder appropriate for a 0.375-inch diameter shank, ensuring proper tool runout before operation. Confirm spindle speed and feed rate settings match the material and cut type before engaging the workpiece. Power down and lock out the machine before changing tooling.\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\u003eLength of Cut\u003c\/strong\u003e: 0.625 inches (5\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 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\u003eNumber of Flutes\u003c\/strong\u003e: 3\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\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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Stub\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\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: 12178600\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51753174499634,"sku":"12178600","price":50.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7f0e8ea84fb95dddc02bd199e3b33c22.jpg?v=1788933508","url":"https:\/\/voomisupply.com\/products\/accupro-12178600-square-end-mill-3-8-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
