Kennametal 1096690 Indexable Profiling Toolholder 0.75 in

Product Description

The KENNAMETAL 1096690 is an external indexable profiling toolholder designed for precision turning and profiling operations on CNC lathes and manual turning centers. Built to the Top Notch series standard, it accepts NP.. 51R inserts held by a clamp-style insert holding method. The toolholder features a neutral hand orientation, a 0 degree lead angle, and a 0.75 x 0.75 inch square shank with a 4.5 inch overall length. These dimensions make it well suited for close-tolerance external profiling passes where consistent tool geometry is critical. Licensed machinists and CNC turning specialists install this holder as part of a precision tooling setup.

This toolholder is intended for external turning and profiling applications in production and job-shop environments. It is a neutral-hand holder, making it appropriate for straight profiling cuts where a dedicated right- or left-hand orientation is not required. The 0 degree lead angle supports full-face engagement and reduces radial cutting forces during profiling passes. Facilities running Top Notch tooling systems will find this holder integrates directly into existing insert and block setups without modification.
