Kennametal 1094848 Indexable Boring Bar 2.5in Left Hand

Product Description

The KENNAMETAL 1094848 is an indexable boring bar designed for internal turning and boring operations in metal cutting applications. Built on the Top Notch series platform, this left-hand holder accepts N-style inserts secured by a clamp holding method, providing rigid and repeatable cutting performance. The bar features a 1.75-inch shank diameter and a 14-inch overall length, supporting a minimum bore diameter of 2.5 inches. A coolant-through design with a 1/4-18 NPT coolant hole thread delivers coolant directly to the cutting zone, reducing heat and extending insert life. Licensed machinists and CNC operators working in production or job-shop environments are the typical end users.

This boring bar is suited for left-hand internal boring operations on lathes and turning centers where coolant-through capability is required. The 3-degree lead angle and 1.25-inch center-to-cutting-edge dimension make it appropriate for moderate-depth bores in ferrous and non-ferrous materials. It is well-suited for production environments requiring consistent, repeatable bore geometry on medium to large-diameter workpieces.

Key Features

• Top Notch series platform with N-style insert compatibility
• Clamp-style insert holding method for secure, repeatable seating
• Coolant-through design with 1/4-18 NPT threaded coolant port
• Left-hand cut orientation for specific lathe setup requirements
• 1.25-inch center-to-cutting-edge dimension for bore geometry control
• Steel construction for rigidity and durability in heavy boring applications

Compatibility

Designed for use with N-style Top Notch indexable inserts. Verify insert geometry and nose radius against job requirements before ordering. No specific machine model compatibility was provided in the product data.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle and turret are fully powered down and locked out before mounting or removing the boring bar. Torque the toolholder clamp screws according to the machine tool manufacturer and insert supplier specifications. Confirm coolant line connection to the 1/4-18 NPT port is leak-free before resuming cutting operations.
