It features a 13\/16 inch length of cut, a 2-1\/2 inch overall length, and a 5\/16 inch cylindrical shank. The tool carries a nano-A coating for improved wear resistance and tool life in demanding materials. With a 4-flute configuration and a variable helix angle of 36 to 38 degrees, it is engineered to reduce chatter and improve chip evacuation during finishing and chamfering passes. Licensed machinists and CNC operators install this tool in milling centers and machining cells.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for single-end chamfering, corner breaking, and edge-prep work on ferrous and non-ferrous workpieces in production shop and job-shop environments. The right-hand cutting direction and right-hand flute direction make it compatible with standard milling machine spindle rotation. The variable helix geometry helps control vibration at higher feed rates, making it appropriate for both roughing chamfers and finish passes where surface quality matters. CNC machinists and tool-and-die professionals are the primary installers of this tool.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction provides rigidity and heat resistance in high-speed cutting applications\u003c\/li\u003e\n\u003cli\u003enano-A coating improves wear resistance and reduces friction at the cutting edge\u003c\/li\u003e\n\u003cli\u003eVariable helix angle of 36 to 38 degrees reduces harmonic vibration and chatter\u003c\/li\u003e\n\u003cli\u003e4-flute, right-hand helical design supports efficient chip flow and surface finish quality\u003c\/li\u003e\n\u003cli\u003eCenter-cutting capable, allowing plunge entry where required\u003c\/li\u003e\n\u003cli\u003eCylindrical shank for direct clamping in collet chucks, end mill holders, or shrink-fit tooling\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style precision cutting tool for use in CNC machining centers and manual milling machines accepting a 5\/16 inch cylindrical shank.

Power down and lock out the machine spindle before inserting or removing the tool from its holder. Seat the shank fully into the collet or tool holder and torque the retention hardware to the tool holder specification. Inspect the cutting edges and coating condition before each use and replace the tool at the first sign of chipping or excessive wear.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\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: nano-A\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: 13\/16 inches (0.8125 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 inches (0.3125 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 36 to 38 degrees (Variable)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Variable Helical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\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: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: GUHRING\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 9030800079400\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51729324081458,"sku":"9030800079400","price":96.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d10e7692d386694e335f99f3fe924d68.jpg?v=1788702909","url":"https:\/\/voomisupply.com\/products\/guhring-9030800079400-corner-chamfer-end-mill-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
