Built from micrograin carbide stock and finished with a titanium carbonitride (TiCN) coating, this tool delivers extended wear resistance in demanding cutting environments. The 3\/16 inch cutting diameter pairs with a 3\/4 inch length of cut and a 40-degree helix angle across three spiral flutes, promoting efficient chip evacuation and reduced cutting forces. At 2-1\/2 inches overall length, it falls into the long-length category, giving machinists added reach without sacrificing rigidity. Centercutting geometry allows for direct plunge entry into workpieces.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for precision slot milling, profiling, and plunge cutting in CNC machining centers and manual milling machines. The long-length configuration is particularly useful when clearance depth is required beyond what a standard-length tool can reach. The right-hand cut and right-hand flute orientation follow conventional milling machine spindle direction. The shank diameter matches the cutting diameter at 3\/16 inch, making it compatible with standard collets and end mill holders in that size range. Typical users include CNC machinists, tool-and-die professionals, and precision machine shops.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for hardness and edge retention\u003c\/li\u003e\n  \u003cli\u003eTiCN coating improves surface hardness and wear resistance over uncoated carbide\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle on spiral flutes promotes smooth chip flow\u003c\/li\u003e\n  \u003cli\u003eCentercutting design enables direct plunge entry without pre-drilling\u003c\/li\u003e\n  \u003cli\u003eLong-length category provides extended reach for deeper features\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute for standard spindle operation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard 3\/16 inch collets and end mill holders in CNC machining centers and manual knee mills.

Seat the shank fully into the collet or holder and torque the retention mechanism per the toolholder manufacturer specification. Verify runout with a dial indicator before beginning a production cut. Consult the machine tool manual and applicable shop safety standards before operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/16 inch (0.1875 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3\/4 inch (0.7500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/16 inch (0.1875 inches)\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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN\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: Long\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: 0.06 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: 12182209\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51744839762226,"sku":"12182209","price":31.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a1646004d5a204ee484a6dcb86779365.jpg?v=1788861327","url":"https:\/\/voomisupply.com\/products\/accupro-12182209-square-end-mill-3-16-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
