Multi-use Holder Solution for Internal Threading

A multi-use holder is a single bushing toolholder that can hold a full set of carbide
shank boring bars capable of grooving, turning, threading, profiling and recessing. The
carbide shanks provide excellent rigidity and a high length-to-diameter (L/D) ratio. This
allows the boring bar overhang to be adjusted to the best rigidity for each job. The new THREAD TURNING
bushing holders incorporate special stoppers, useful in many applications with ISCAR’s
CHAMGROOVE system and PICCO bars. Utilizing the stoppers eliminates resetting the tool
after every indexing. This versatile system replaces many expensive boring bars needed to
perform the variety of applications, which are now possible with this single bushing holder.
These holders are available with coolant channels.
