Kennametal 1094655 Indexable Boring Bar 15.24mm Right Hand

Product Description

The KENNAMETAL 1094655 is a right-hand A-STFP indexable boring bar engineered for precision internal turning operations. Built from steel, it accepts TP-series inserts held in place by a screw-clamp method and features a through-coolant design to manage heat and chip evacuation at the cutting zone. The bar has a minimum bore diameter of 15.24mm (0.600 inches), an overall length of 203.2mm (8.0 inches), and a 12.70mm (0.5 inch) round shank. The neutral rake geometry at 0 degrees suits a broad range of workpiece materials and insert grades commonly used in production and job-shop environments.

This boring bar is suited for CNC lathes and turning centers where a 0.5-inch shank bore bar is required for small-diameter internal operations. The through-coolant port threads at 1/16-27 NPT, allowing direct connection to the machine tool coolant system. The 7.93mm (0.312 inch) center-to-cutting-edge dimension supports close-bore entry. Machinists and tooling technicians working in general machining, aerospace, and precision-parts manufacturing will find this bar appropriate for finish and semi-finish boring passes requiring consistent insert indexing.

Key Features

• Minimum bore diameter of 15.24mm (0.600 inches) for small-bore internal turning
• Through-coolant design with 1/16-27 NPT coolant port for directed chip and heat control
• Screw-clamp insert holding method for secure, repeatable TP-series insert indexing
• Neutral rake (0 degrees) geometry compatible with a wide range of insert grades and materials
• Steel construction with 12.70mm (0.5 inch) shank diameter for standard machine tool interfaces
• 1/4-inch insert inscribed circle with 3/32-inch insert thickness for TP-compatible inserts

Compatibility

Designed for use with TP-series (TP..) indexable inserts. Intended for installation in machine tool spindles or turrets accepting a 0.5-inch round shank boring bar.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician with the machine fully powered down and in an e-stop or lockout-tagout state before bar mounting or insert changes. Secure the shank in the turret or boring head to the tool manufacturer's recommended clamping practice for the machine type. Connect the through-coolant supply to the 1/16-27 NPT port using compatible fittings and verify coolant flow before beginning the cut. Index or replace TP-series inserts using the appropriate Torx or hex key driver per the insert screw specification.
