Kennametal 1095908 Indexable Profiling Toolholder 0.625 in

Product Description

The KENNAMETAL 1095908 is a left-hand external indexable profiling toolholder designed for precision turning and profiling operations on CNC lathes and turning centers. Built to the Top Notch series standard, it features a 5-degree lead angle and a neutral rake configuration using a clamp-style insert holding method. The steel shank measures 0.625 inches in diameter and the toolholder has an overall length of 10 inches. It accepts NP.. series inserts, specifically the NP.. 51R, and includes a 1/8-27 NPT coolant-through port to support high-pressure coolant delivery at the cutting zone. Designed for machinists and tooling technicians in production and job-shop environments.

This toolholder is suited for external profiling passes on turned components where controlled lead angle and consistent insert presentation are required. The left-hand orientation accommodates specific tool path directions on CNC turning machines. The coolant-through design helps manage chip evacuation and heat at the insert during interrupted or continuous cuts. The Toolholder Style designation is A-NKLC, and the center-to-cutting-edge dimension of 0.500 inches supports precise part geometry control. It is appropriate for both light finishing and general-purpose profiling in steel and similar workpiece materials.

Key Features

• External, left-hand profiling toolholder with 5-degree lead angle and neutral rake
• Accepts NP.. series inserts (compatible insert: NP.. 51R) via clamp-style holding method
• Coolant-through capability with 1/8-27 NPT coolant hole thread for directed cutting fluid delivery
• Steel construction for rigidity and dimensional stability under turning loads
• Center-to-cutting-edge distance of 0.500 inches for predictable geometry setup
• Top Notch series design for repeatable insert indexing and consistent cutting performance

Compatibility

Compatible with NP.. 51R inserts as specified for the Top Notch series. Insert size code NP.. applies. Toolholder style A-NKLC. Designed as an OEM-style replacement or direct-fit toolholder for external turning and profiling applications using Top Notch series compatible inserts.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Power down and lock out the machine spindle before changing or seating the toolholder. Ensure the insert pocket is clean and free of chips before indexing or replacing the NP.. insert. Verify coolant line connection to the 1/8-27 NPT port is properly sealed before resuming coolant-through operation.
