TopThread™ inserts are available in TN6010™ and TN6025™ grades to withstand the demands placed on the cutting edge of the threading insert.
The versatility of the TopThread steel enables you to use both threading and grooving inserts in the same toolholder.
With the WIDIA™ TopThread solution, there is no need to worry about costly setup mistakes. TopThread insert selection is easy, quick, and enables accurate indexing to keep your machine spindle turning.
NOTE: Holders are designed to locate inserts inclined to 3° to provide back clearance down open side.
