Kennametal 1095158 Replaceable Boring Bar Head Steel

Product Description

The KENNAMETAL 1095158 is a steel replaceable boring bar head designed for precision internal turning and boring operations on CNC and manual lathes. It accepts CPMT21.51 indexable inserts, allowing fast insert changes without removing the boring bar body from the machine. The steel construction provides rigidity and durability in standard boring applications. This head is suited for machinists and toolroom professionals working with modular boring systems where quick head swaps are required to change cutting geometry or accommodate varying bore diameters and depths.

This replaceable head is used in metalworking environments where modular tooling systems are preferred over solid boring bars. It fits into compatible KENNAMETAL boring bar bodies that accept this head style and is appropriate for both production machining and job-shop applications. The CPMT21.51 insert style is a standard indexable format, giving operators access to a wide range of insert grades and geometries for different workpiece materials and cutting conditions.

Key Features

• Accepts CPMT21.51 indexable inserts for broad insert grade and geometry selection
• Steel construction for rigidity in standard internal boring applications
• Replaceable head design allows quick tooling changes without disturbing bar setup
• Modular system compatibility reduces tooling inventory requirements
• Sold individually (package quantity of 1)

Compatibility

Designed for use with KENNAMETAL modular boring bar bodies that accept this replaceable head style. Uses CPMT21.51 indexable inserts. Consult KENNAMETAL tooling documentation to confirm body compatibility before ordering.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel. Before mounting or changing the boring bar head, ensure the machine spindle is fully stopped and locked out per OSHA lockout/tagout procedures. Use the manufacturer-specified torque wrench and fasteners when securing the head to the bar body — do not overtighten or substitute fasteners. Verify insert seating and clamp engagement before resuming cutting operations.
