It features a 9\/64 inch (0.1406 inch decimal) cutting diameter with a 4-flute, spiral flute geometry and a 40-degree helix angle. The TiCN (Titanium Carbonitride) coating improves surface hardness and heat resistance compared to uncoated carbide. The micrograin carbide substrate provides the toughness and edge retention needed for demanding cut conditions. This end mill is centercutting, allowing plunge cuts in addition to peripheral and slot milling. It is installed and operated by machinists and tool-and-die tradespeople on CNC machining centers and manual mills.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for regular-length slotting, profiling, and plunge milling in ferrous and non-ferrous materials where a small-diameter, high-precision cutting tool is required. The 9\/64 inch diameter makes it appropriate for fine detail work, narrow slots, and close-tolerance contour passes. The right-hand cut and right-hand flute configuration is standard for conventional spindle rotation. The 1\/2 inch length of cut and 2 inch overall length place this tool in the regular-length category, keeping it rigid for reduced deflection at small diameters.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for edge retention and wear resistance\u003c\/li\u003e\n\u003cli\u003eTiCN finish for improved hardness and thermal resistance at the cutting edge\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle promotes smooth chip evacuation and reduced cutting forces\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry into workpiece material\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute for standard CNC and manual mill spindle use\u003c\/li\u003e\n\u003cli\u003eTight mill diameter tolerance of +0.000\/-0.002 inches for consistent fit and finish\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard straight-shank end mill for use in 3\/16 inch collets or end mill holders on CNC machining centers, knee mills, and similar milling machines capable of accepting round-shank tooling.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following the machine tool builder guidelines for collet torque and tool projection. Confirm the holder or collet is clean and free of debris before seating the shank. Always verify spindle speed and feed rate settings match the material and tool diameter before initiating a cut. Power down and lock out the spindle before changing or measuring tooling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 9\/64 inch (0.1406 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\/2 inch (0.5000 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\u003eOverall Length\u003c\/strong\u003e: 2 inches\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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\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\u003eFinish\u003c\/strong\u003e: TiCN\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\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: 12182398\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51738537361714,"sku":"12182398","price":31.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bf38f35f80187b2cab560ea748144188.jpg?v=1788800753","url":"https:\/\/voomisupply.com\/products\/accupro-12182398-square-end-mill-9-64-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
