Kennametal 1094841 Indexable Boring Bar 2.25in Right Hand

Product Description

The KENNAMETAL 1094841 is a steel indexable boring bar designed for precision internal turning and boring operations on CNC lathes and machining centers. Built to the A28NER3 toolholder configuration, it uses a clamp-style insert holding method compatible with Top Notch series N-style inserts. The bar features a 1.75-inch shank diameter and a 14-inch overall length, providing the rigidity and reach needed for deep-bore applications. A 1/4-18 NPT coolant-through port delivers cutting fluid directly to the insert, supporting extended tool life and chip evacuation in demanding materials. Licensed machinists, CNC operators, and toolroom technicians install this bar in production and job-shop environments.

This boring bar is suited for right-hand internal turning operations requiring a minimum bore diameter of 2.25 inches. The 3-degree lead angle and center-to-cutting-edge dimension of 1.125 inches position the insert for consistent, repeatable cuts. The coolant-through design makes it a practical choice for deep-bore steel, cast iron, and similar workpiece materials where chip control and heat management are critical. It is a single-application tool (Multi-use Tool: No), intended for dedicated boring setups rather than combination operations.

Key Features

• Clamp-style insert retention for secure, repeatable Top Notch N-style insert seating
• Coolant-through port with 1/4-18 NPT thread for directed coolant delivery at the cutting edge
• 2.25-inch minimum bore diameter accommodates a wide range of internal turning applications
• 14-inch overall length provides extended reach for deep-bore setups
• 1.75-inch shank diameter delivers rigidity and resistance to deflection under load
• Right-hand cut orientation for standard CNC lathe spindle configurations

Compatibility

Designed for use with Top Notch series N-style indexable inserts. Confirm insert geometry, grade, and chip-breaker selection against KENNAMETAL Top Notch tooling documentation before ordering inserts.

Installation Notes

Installation is performed by qualified CNC machinists or toolroom technicians. Power down and lock out the machine spindle before mounting or removing the boring bar. Confirm shank-to-toolholder bore fit and torque all clamping screws per the machine tool manufacturer specifications. Connect the coolant-through supply line to the 1/4-18 NPT port and verify flow before beginning the cut.
