EVX endmillwith centre cutting edge for plunge millingN E WFeaturesModern machining processes demand forflexible application and highest productivity.Tungaloy set a sign and developed anew tool concept. The multi-functionalEVX endmill is the result of an elaboratemarket analysis carried out amongst acarefully chosen and well balanced circleof end-users from the Die and Mould industry,machine tool industry and fixtureconstruction but also machine constructionindustry and repair shops.The innovative EVX endmill is a double cuttingendmill with centre cutting edge bestsuited for a multitude of different applications.These are next to conventionalmilling operations as shoulder milling andslotting also plunging operations into thefull material.Especially the effective double clampingmechanism of the insert by clamp screwand form fit extraordinarily compensatescutting forces developing from differentsources and directs these into the insertseat. The result is higher stability of thewhole tool system and an optimised completemachining process.N E WBenefitsDouble clampingInsert is fixed with clamp screwand form fit for highest stability.Optimal fixing through the inclinationof the clamping screwMaximal rigidityNew Torx-Plus clamp screw for20 % increase of clamp torqueUniqueSpecial marks on inserts andcutter body for easy indexingAir holeEffecient coolant supply (coolinglubricant or compressed air)Wide range of applicationsCentre cutting edge for plunge millingOne geometry for internal andperipheral cutting edgeTorx-Plus clamp screw for maximalrigidity2
