Built from micrograin solid carbide with a TiCN (Titanium Carbonitride) finish, this tool delivers extended wear resistance and thermal stability under demanding cutting conditions. It features a 3\/8 inch cutting diameter, a 1-3\/4 inch length of cut, and a 4 inch overall length, placing it in the extra-long category for reaching deeper pockets and slots. The 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. This end mill is installed and used by machinists, tool-and-die makers, and CNC operators in job shops and production environments.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for milling slots, pockets, profiles, and contours in ferrous and non-ferrous materials where a longer reach is required. The 3 spiral flutes provide a balance between chip clearance and wall support, making it appropriate for both roughing and semi-finishing passes. The TiCN coating increases surface hardness and reduces friction, extending tool life in steel, stainless, cast iron, and similar materials. The 3\/8 inch shank diameter matches standard collets and end mill holders common in vertical machining centers and CNC mills.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrograin solid carbide construction for rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003eTiCN finish improves hardness and reduces heat buildup at the cutting edge\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle promotes efficient chip evacuation and smooth surface finish\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 orientation for standard CNC mill spindle rotation\u003c\/li\u003e\n  \u003cli\u003eExtra-long length of cut (1-3\/4 inches) suits deep pocket and slot milling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement or standard tooling selection for any milling machine or machining center equipped with a 3\/8 inch collet, end mill holder, or shrink-fit holder accepting a 3\/8 inch shank diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator following the machine tool manufacturer guidelines. Ensure the spindle is fully stopped and the machine is powered down or in a safe state before changing tooling. Secure the shank to the minimum recommended insertion depth in the holder to maintain concentricity and reduce runout. Consult applicable speeds and feeds data for TiCN-coated carbide tooling based on workpiece material before beginning a cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-3\/4 inch (1.7500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiCN\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\u003eLength Type\u003c\/strong\u003e: Extra 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: 0.4 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: 12182248\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51734998450482,"sku":"12182248","price":77.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c720d224128fa2c8c1ed12a327f678ea.jpg?v=1788769041","url":"https:\/\/voomisupply.com\/products\/accupro-12182248-square-end-mill-3-8-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
