Kennametal 1097508 Indexable Profiling Toolholder External

Product Description

The KENNAMETAL 1097508 is an external indexable profiling toolholder designed for turning and profiling operations on CNC lathes and turning centers. Built to the Top Notch series standard, this right-hand toolholder features a neutral rake geometry and a clamp-style insert holding method. The steel shank measures 0.75 inches in height and 0.75 inches in width, with an overall length of 4 inches. It accepts NP.. series inserts with a 5/8-inch inscribed circle, making it a direct-fit choice for shops already running Top Notch tooling systems. Coolant-through capability is not included on this holder.

This toolholder is suited for external turning and contour profiling in general machining environments, including job shops and production turning cells. The NKLC toolholder style with a -5 degree lead angle supports profiling passes where controlled cutting geometry is required. It is appropriate for use on short-run and high-volume applications where quick insert indexing and repeatable tool positioning are priorities. Compatible insert size code NP.. 51R is the designated insert family for this holder.
