Kennametal 1152607 Indexable Boring Bar Left Hand Solid Carbide

Product Description

The KENNAMETAL 1152607 is a solid carbide indexable boring bar designed for internal turning and boring operations on CNC lathes and turning centers. Designated style E10NEL2 KWH, this left-hand holder accepts N-style inserts secured by a clamp-style holding method. It features a minimum bore diameter of 1 inch and an overall length of 10 inches, making it suitable for moderate-depth boring applications where rigidity and precision are critical. A built-in coolant-through channel with a 0.2200-inch diameter coolant hole delivers cutting fluid directly to the insert tip, improving chip evacuation and tool life in demanding materials. Licensed machinists and CNC operators working in production or job-shop environments are the primary installers of this toolholder.

This boring bar is built for use in horizontal and vertical turning centers requiring left-hand internal boring capability. The 5/8-inch shank diameter fits standard boring bar holders and quick-change tooling systems common in production turning setups. The Top Notch series designation indicates compatibility with that insert platform. The center-to-cutting-edge dimension of 0.5000 inches supports consistent bore sizing when dialing in offsets. It is well suited for machining steel, cast iron, and similar ferrous materials where coolant-through capability provides a measurable advantage in tool life and surface finish.

Key Features

• Left-hand cut orientation for internal boring on CNC lathes and turning centers
• Solid carbide construction provides high rigidity and resistance to deflection in deep-reach applications
• Coolant-through design with 0.2200-inch coolant hole for direct tip cooling and chip flushing
• Clamp-style insert retention for reliable indexing and repeatable cutting geometry
• 10-inch overall length with 1-inch minimum bore diameter covers a practical range of internal feature sizes
• Top Notch series compatibility with N-style inserts for broad insert selection

Compatibility

Designed for use with N-style inserts in the Top Notch series insert platform. Fits standard 5/8-inch shank boring bar pockets and quick-change tooling blocks configured for that shank diameter.

Installation Notes

Installation is performed by a qualified CNC machinist or tooling setup technician. Power down the machine and engage the spindle lock before mounting or removing the boring bar from the turret. Confirm shank clamp torque per the machine tool builder specifications and verify insert seating and clamp integrity before running. Use the correct N-style insert geometry and grade for the workpiece material, and confirm coolant-through passages are clear and properly connected before initiating a cut.
