SEC-Plunge Drill   SEC-Plunge Mill PDL Type / PCT Type PDL Type PCT Type ■ General Features The tool cuts in the Z axis direction where tool rigidity is highest, allowing high efficiency roughing for aeronautic components and dies with long tool overhang must be used to machine deep holes and pockets. ■ Characteristics ● The flat cutting edge design produces near-flat bottom profiles to reduce depth of cut variation during finishing. ● All sizes come with an air hole for supplying coolant internally to improve chip evacuation. ● Durable body with special surface treatment offers improved tool life and reliability. ● The tools use SumiDrill WDX type inserts for handling a wide range of work materials, from steel to non-ferrous metals and exotic alloys. ● The PDL type has a central insert making it possible ● Although the PCT type has limited radial cutting ability, the tool to make radial cuts beyond the tool's radius, pitch has many effective teeth enabling it to perform high feed cutting. feed cutting, and drilling.
