It features a 7\/16 inch cutting diameter, a 9\/16 inch length of cut, and a 3-flute spiral configuration with a 40-degree helix angle. The AlTiN coating provides heat and wear resistance, making it well suited for higher-speed dry or semi-dry cutting operations. The stub-length profile keeps deflection low during aggressive side-milling passes. This tool is installed and operated by machinists, tool-and-die makers, and CNC machine operators in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for CNC machining centers and manual mills where a short, rigid tool is needed for slotting, profiling, and pocket milling in harder materials. The centercutting design allows plunge entry without a pre-drilled pilot hole. Right-hand cut and right-hand flute geometry follow standard milling conventions for most vertical machining center setups. The micrograin carbide substrate supports higher surface footage than standard carbide grades, extending tool life in demanding cuts.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for extended tool life and edge retention\u003c\/li\u003e\n\u003cli\u003eAlTiN finish for elevated heat resistance in high-speed and dry cutting applications\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle improves chip evacuation and reduces cutting forces\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows direct plunge entry into the workpiece\u003c\/li\u003e\n\u003cli\u003eStub length (9\/16 inch LOC, 2-3\/4 inch OAL) minimizes deflection in tight setups\u003c\/li\u003e\n\u003cli\u003eRight-hand cut with right-hand spiral flutes — compatible with standard spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard 7\/16 inch collets, end mill holders, or shrink-fit toolholders on CNC machining centers and manual knee mills.

Seat the 7\/16 inch shank fully into the holder to the recommended gage-line depth before torquing the retention system to the toolholder manufacturer's specification. Inspect the cutting edges and coating for chips or wear before each use. Tool runout should be verified with a dial indicator after installation; excessive runout accelerates edge wear and reduces surface finish quality.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 7\/16 inch (0.4375 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 9\/16 inch (0.5625 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 7\/16 inch (0.4375 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\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)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN\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: 0.25 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: 12176620\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51728296509746,"sku":"12176620","price":65.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8dee963343ef32e23a522c2dd2120ef6.jpg?v=1788690325","url":"https:\/\/voomisupply.com\/products\/accupro-12176620-square-end-mill-7-16-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
