Kennametal 1096135 Indexable Turning Toolholder MCKNR204D

Product Description

The KENNAMETAL 1096135 is a right-hand indexable turning toolholder in the Kenloc series, designed for use with CN-style negative-rake inserts. The toolholder accepts a CN..43. insert with a 0.5000-inch inscribed circle and uses a clamp screw holding method to secure the insert under cutting loads. The shank measures 1.25 x 1.25 inches in cross-section with an overall length of 6 inches. Constructed from steel, this toolholder is intended for CNC lathe and turning center applications and is installed by machinists, tooling setters, and shop technicians working in production or jobbing environments.

This toolholder is suited for external turning operations on conventional or CNC lathes where right-hand cutting direction is required. The negative-rake geometry of the insert seat accommodates heavy interrupted or continuous cuts. The MCKNR204D style designation reflects the insert geometry and shank dimensions, making it a direct selection for shops already running CN-style insert programs. It is not configured for coolant-through delivery, so external coolant application is required in wet-machining setups.

Installation Notes

Installation is performed by qualified machinists or tooling setup personnel. Before changing inserts or mounting the toolholder, confirm the machine spindle is fully stopped and locked out per shop lockout/tagout procedures. Seat the toolholder squarely in the turret or toolpost and tighten all clamping fasteners to the machine manufacturer's specifications. Inspect the insert seat and clamp screw for wear or debris before each insert change to ensure proper seating and cutting-edge alignment.
