With a 0.3125-inch mill diameter and a 1-inch length of cut, this tool delivers consistent material removal in contouring, profiling, and 3D surface work. The 4-flute geometry combined with a 40-degree helix angle improves chip evacuation and surface finish. Micrograin carbide construction provides edge hardness and wear resistance suited to demanding cutting conditions. The uncoated finish makes it compatible with a wide range of cutting fluids and work materials. A long-length body at 4 inches overall gives added reach for deeper cavities.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for CNC machining centers and manual mills where tight tolerances and smooth finishes are required. The single-end, right-hand cutting and right-hand spiral flute configuration is standard for conventional and climb milling setups. Long-length geometry makes it a practical choice for mold work, die cavities, and contoured part features that cannot be reached with standard-length tooling. It is a common selection in job shop, tool-and-die, and production machining environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for superior edge retention and hardness\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle promotes efficient chip evacuation and reduces heat buildup\u003c\/li\u003e\n  \u003cli\u003e4-flute design balances material removal rate with surface finish quality\u003c\/li\u003e\n  \u003cli\u003eLong-length body at 4 inches OAL provides extended reach into deep cavities\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand spiral flute for standard CNC and manual mill setups\u003c\/li\u003e\n  \u003cli\u003eUncoated finish compatible with a broad range of workpiece materials and cutting fluids\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard single-end ball nose end mill with a 5\/16-inch shank diameter, compatible with ER and straight-bore collet systems sized for 5\/16-inch tooling on CNC machining centers and manual milling machines.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Verify collet size matches the 5\/16-inch shank diameter and that the tool is seated to the full recommended insertion depth before tightening. Inspect the cutting edges and shank for damage before each use; carbide tooling is brittle and should not be used if chipped or cracked.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.3125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3125 inches (5\/16 inches)\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\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 Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Long\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 to -0.002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 to -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\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: 12184934\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51737153405234,"sku":"12184934","price":83.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b587e7732c13179a24acd7b86c2b0b65.jpg?v=1788784990","url":"https:\/\/voomisupply.com\/products\/accupro-12184934-ball-end-mill-0-3125-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
