Tool
DHR237R（Long Neck Radius Type）
●Long neck corner radius end mill specialized for machining copper electrode.
●37.5º helix angle provides both sharpness shearing ability and finishing surface quality, combining the most suitable cutting edge design realizes the higher quality of finishing surface.
●High quality and stable milling performance with long tool life by optimized design and DLC coating.
●Machining copper tungsten electrodes is also effective.
