Built from micrograin carbide, it delivers hardness and edge retention in a compact 1\/16 inch (0.0625 inch) diameter profile. The 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. With a bright\/uncoated finish, this end mill suits applications where coating buildup tolerance is not required. It is a single-end tool with right-hand cutting and right-hand flute direction, sized for tight-tolerance work in prototype shops, tool rooms, and production machining environments.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for small-feature milling operations including slots, pockets, and contour paths in aluminum, brass, mild steel, and similar materials. The 3\/16 inch length of cut and 1-1\/2 inch overall length make it appropriate for shallow-depth passes in die work, mold machining, and precision part fabrication. It is centercutting, allowing direct plunge entry. Machinists and CNC operators running small-diameter toolpaths on vertical machining centers or CNC routers will find this tool applicable to fine detail work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for hardness and edge retention\u003c\/li\u003e\n\u003cli\u003e4-flute spiral design with 30-degree helix for efficient chip flow\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows direct plunge milling\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish suitable for non-ferrous and general-purpose applications\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction\u003c\/li\u003e\n\u003cli\u003eSingle-end configuration with close mill diameter tolerance of +0.0000\/-0.0010 inches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard tooling option for CNC machining centers and manual mills accepting a 1\/8 inch shank diameter collet or tool holder.\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 changing tooling. Seat the 1\/8 inch shank fully into a collet or end mill holder and torque to the tool holder specification. Verify runout with a dial indicator before engaging the workpiece, as small-diameter carbide end mills are sensitive to runout and may fracture under side load if improperly seated.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/16 inch (0.0625 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0000 \/ -0.0010 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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\u003eLength of Cut\u003c\/strong\u003e: 3\/16 inch (0.188 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-1\/2 inches (1.5 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/8 inch (0.125 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 \/ -0.0003 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 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\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Helix\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\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 12378441\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51750545260850,"sku":"12378441","price":23.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c049f4815dc5287329bafa5e20521864_a62447ec-c6ab-44e8-bd4c-6e8513f337aa.jpg?v=1788916468","url":"https:\/\/voomisupply.com\/products\/accupro-12378441-square-end-mill-1-16-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
