Kennametal 1094747 Indexable Boring Bar Right Hand Steel

Product Description

The KENNAMETAL 1094747 is an indexable boring bar designed for internal turning and boring operations on CNC lathes and manual turning centers. Built on an A-STLP toolholder style with a 1/2-inch (12.70 mm) shank diameter and an overall length of 8 inches (203.20 mm), it delivers rigid, repeatable performance in a compact form factor. The bar features a screw-clamp insert holding method and accepts TP-style inserts with a 1/4-inch inscribed circle and 3/32-inch thickness. A neutral rake angle and a -5 degree lead angle suit a wide range of steel and alloy-boring applications. A built-in coolant-through port with a 1/16-27 NPT thread size supports chip evacuation and tool life in continuous-cut conditions.

This boring bar is suited for right-hand boring passes on lathes requiring a minimum bore diameter of 0.600 inches (15.24 mm). It is a single-purpose, non-multi-use holder intended for precision internal diameter work in production and job-shop environments. Machinists and CNC programmers running tight-tolerance bores in steel, alloy steel, and similar materials will find the neutral rake geometry and screw-clamp security appropriate for finishing and semi-finishing passes where insert indexing speed and repeatability matter.

Key Features

• Minimum bore diameter of 0.600 inches (15.24 mm) for small-bore internal turning
• A-STLP toolholder style with right-hand cut orientation
• Screw-clamp insert retention for secure, repeatable indexing of TP-style inserts
• Neutral rake (0 degrees) with -5 degree lead angle for controlled chip formation
• Coolant-through design with 1/16-27 NPT port to support chip evacuation and thermal management
• Steel construction with 1/2-inch shank diameter and 8-inch overall length

Compatibility

Accepts TP-style inserts with a 1/4-inch inscribed circle and 3/32-inch insert thickness. Verify toolholder pocket and insert geometry match before ordering replacement inserts.

Installation Notes

Installation is performed by a machinist or CNC tooling technician. The machine spindle must be at a full stop and all power isolated before mounting or removing the boring bar from the turret or tool block. Use calibrated torque tools when seating the insert screw to avoid over-torquing the clamp. Confirm shank-to-bore clearance and reach requirements against the workpiece setup before committing to a tool path.
