Kennametal 1098795 Indexable Threading Toolholder 20x20mm

Product Description

The KENNAMETAL 1098795 is an external, right-hand indexable threading toolholder in the Top Notch series, designed for precision thread-turning operations on CNC lathes and turning centers. It accepts N.3R inserts held in place by a clamp-style insert holding method, providing secure, repeatable seating during external threading passes. The shank measures 20 millimeters wide by 20 millimeters tall (0.7874 inches square), with an overall length of 125 millimeters (4.9213 inches). Maximum depth of cut reaches 5.30 millimeters (0.2087 inches). The toolholder style is NS, consistent with Top Notch system geometry. Machinists and CNC operators working in production or job-shop environments will find this holder suitable for right-hand external thread profiles on ferrous and non-ferrous materials.

This toolholder is intended for external threading applications on turning equipment where a 20 x 20 mm square shank is required. The right-hand configuration suits standard lathe setups cutting threads in the conventional direction. The Top Notch series is a recognized platform in indexable threading, and this holder is appropriate for shops running production threading cycles where consistent insert indexing and clamping rigidity matter. It does not include coolant-through capability, making it suited for flooded coolant or dry threading environments rather than high-pressure through-tool coolant systems.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Before mounting or changing inserts, the machine must be powered down and the spindle must be fully stopped. The toolholder should be secured in the tool block or turret according to the machine manufacturer torque guidelines for the fastener size used. Confirm insert seating and clamp engagement before resuming any cutting operations.
