It measures 0.2969 inches (19\/64 inch) in diameter with a 3\/4-inch length of cut and a 2-1\/2-inch overall length. The 5\/16-inch shank accepts standard collet chucks and end mill holders. Three spiral flutes with a 40-degree helix angle promote efficient chip evacuation and reduce cutting forces. A TiCN (Titanium Carbonitride) coating improves wear resistance and surface hardness compared to uncoated carbide. The micrograin carbide substrate supports tight tolerances and extended tool life in demanding cuts. This tool is installed and used by machinists and tool-and-die professionals in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for slotting, profiling, and plunge operations in ferrous and non-ferrous metals as well as plastics and composites. The centercutting geometry allows direct plunge entry without a pre-drilled pilot hole. Right-hand cut and right-hand flute configuration is standard for conventional CNC machining center spindles. The regular length designation makes it a practical choice for general-purpose milling where extended reach is not required. It is appropriate for both horizontal and vertical milling setups on manual and CNC machines.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003eTiCN coating increases surface hardness and reduces tool wear in ferrous materials\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle promotes smooth chip flow and reduced cutting pressure\u003c\/li\u003e\n  \u003cli\u003eCentercutting design enables direct plunge milling without a pilot hole\u003c\/li\u003e\n  \u003cli\u003eMill diameter tolerance of +0.000 \/ -0.002 inches for precise fit and finish\u003c\/li\u003e\n  \u003cli\u003eThree flutes balance chip clearance and cutting edge strength for medium-to-hard materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct selection for standard 5\/16-inch collet chucks and end mill holders used in CNC machining centers and manual milling machines requiring a 19\/64-inch diameter square end mill.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist following shop safety procedures. Secure the shank fully into a clean, undamaged collet or end mill holder and torque to the tool holder manufacturer's specification. Inspect the cutting edges for chips or coating damage before each use. Never exceed the tool's rated speed and feed parameters for the workpiece material being machined.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 19\/64 inch (0.2969 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: 5\/16 inch (0.3125 inches)\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\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\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\u003eLength Type\u003c\/strong\u003e: Regular\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: 12181978\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51730678022450,"sku":"12181978","price":59.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b52576aeab3bdb04f1d425da8ea541b6_12bde33f-db70-4aed-a79d-19651a486ce3.jpg?v=1788721344","url":"https:\/\/voomisupply.com\/products\/accupro-12181978-square-end-mill-19-64-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
