With a 3\/4 inch (19.05 mm) mill diameter, a 4-flute helical configuration, and a variable helix angle ranging from 42 to 45 degrees, this head delivers stable cutting and reduced chatter in demanding materials. The AlCrN coating provides thermal resistance and extended tool life in dry or semi-dry cutting environments. It connects via the iMX20 interface, making it a modular insert-style head for compatible tooling systems. Installation and removal are handled by qualified machinists or toolroom personnel.\u003c\/p\u003e\u003cp\u003eThis end mill head is suited for finish milling, chamfering, and corner radius profiling on ferrous and non-ferrous metals in both production and job-shop environments. The variable helix and variable index geometry help suppress harmonic vibration during aggressive cuts. With a 3\/4 inch length of cut and a corner radius of 0.060 inch (1.52 mm), it is well matched to contouring and edge-blending operations on mold, die, and precision machined components. It is not center-cutting and should not be used for direct plunge operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard materials\u003c\/li\u003e\n\u003cli\u003eAlCrN coating for high thermal stability and extended tool life\u003c\/li\u003e\n\u003cli\u003eVariable helix (42 to 45 degrees) and variable index geometry reduce vibration and chatter\u003c\/li\u003e\n\u003cli\u003eiMX20 modular connection for secure, repeatable head changes\u003c\/li\u003e\n\u003cli\u003e4-flute right-hand helical flute design for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCorner radius of 0.060 inch (1.52 mm) protects edge integrity and improves surface finish\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with iMX20 modular end mill systems.

Ensure the machine spindle is fully stopped and the toolholder is secured in a stable fixture before seating or removing the head. Do not use this head for plunge cutting, as it is not center-cutting. Verify runout with a dial indicator after assembly to confirm proper seating.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.750 inches (19.05 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.750 inches (19.05 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.008 inches (51.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.060 inches (1.52 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Helical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: Variable, 42 to 45 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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: AlCrN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: iMX20\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.24 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MITSUBISHI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 682734\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MITSUBISHI ELECTRIC","offers":[{"title":"Default Title","offer_id":51722282238258,"sku":"682734","price":386.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c8bf6be245302dcb06de7bb581901b84.jpg?v=1788588612","url":"https:\/\/voomisupply.com\/products\/mitsubishi-682734-corner-chamfer-end-mill-3-4-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
