Kennametal 1096149 Indexable Turning Toolholder MSRNR124B

Product Description

The KENNAMETAL 1096149 is an MSRNR-style indexable turning toolholder from the Kenloc series, designed for negative-rake external turning operations on CNC lathes and manual turning centers. The right-hand holder uses a clamp and screw insert-holding method to lock SN-style inserts securely under cutting loads. The steel shank measures 3/4 inches wide by 3/4 inches tall with an overall length of 4.5 inches. The head length is 1.23 inches and the back-of-bar to cutting edge distance is 0.88 inches, giving machinists a defined geometry for toolpost setup. Coolant-through capability is not included in this configuration.

This toolholder is suited for turning applications in production shops, job shops, and maintenance machining environments. The MSRNR style is a common choice for general-purpose OD turning where consistent insert indexing and rigid clamping are priorities. The Kenloc clamping system is intended for use with SN-style inserts having a 0.5-inch inscribed circle, making insert sourcing straightforward. A licensed machinist or CNC operator typically handles setup and insert changes on this type of toolholder.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. Power down and lock out the lathe spindle before inserting or indexing cutting inserts. Seat the shank fully in the toolpost or turret and torque the clamping fasteners according to the machine manufacturer and toolholder documentation. Inspect the insert pocket and clamping surfaces for chips or debris before each insert change to maintain accurate cutting geometry.
