It features a 3\/4 inch cutting diameter, a 1 inch length of cut, and a 45-degree helix angle with a ZrN (zirconium nitride) coating for extended tool life and improved chip evacuation. The micrograin carbide construction provides rigidity and wear resistance in demanding cutting conditions. This is a single-end, stub-length tool suited for high-speed milling applications where dimensional accuracy and surface finish are critical. Machinists and CNC operators install this tool in standard 3\/4 inch tool holders or collet chucks.\u003c\/p\u003e\u003cp\u003eThe 313422 is used in job shop, production, and tool room environments for slotting, profiling, and peripheral milling operations. It is well-suited for ferrous and non-ferrous materials where a ZrN coating provides lubricity and heat resistance. The right-hand cut and right-hand spiral flute configuration make it compatible with standard CNC machining centers and manual vertical mills. Its stub-length design increases rigidity and reduces deflection in shorter-reach applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/4 inch cutting diameter with a tight mill diameter tolerance of +0.000 \/ -0.002 inches\u003c\/li\u003e\n\u003cli\u003eZrN coating improves lubricity, heat resistance, and tool life versus uncoated carbide\u003c\/li\u003e\n\u003cli\u003e45-degree helix angle promotes efficient chip evacuation and smooth cutting action\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate for superior rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eCenter-cutting design allows for direct plunge entry into the workpiece\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction for standard spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC machining centers and manual mills accepting a 3\/4 inch straight shank with a shank diameter tolerance of +0.0001 \/ -0.0004 inches.

Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Verify that the holder bore and collet are clean and free of chips before seating the shank. Do not exceed the tool manufacturer's recommended speeds and feeds for the workpiece material and coating type.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/4 inches (0.7500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/4 inches (0.75 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: ZrN (Zirconium Nitride)\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\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: 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: 0.1 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: 313422\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51730848153906,"sku":"313422","price":252.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/52d68e9b941bdfe324b255d99a22fdea.jpg?v=1788723802","url":"https:\/\/voomisupply.com\/products\/accupro-313422-square-end-mill-3-4-in-2-flute-carbide-zrn","provider":"Voomi Supply","version":"1.0","type":"link"}
