Kennametal 1094733 Indexable Boring Bar 1 in Shank

Product Description

The KENNAMETAL 1094733 is a steel-body indexable boring bar designed for internal turning and boring operations on CNC lathes and machining centers. Built to the A16SCFPR3 toolholder style, it accepts CP-style inserts secured by screw clamping, providing repeatable positioning and quick insert changes at the machine. The shank diameter is 1 inch (25.40 mm), the minimum bore diameter is 1.200 inches (30.48 mm), and the overall length is 12.000 inches (304.80 mm). A neutral rake angle of 0 degrees keeps cutting forces balanced across a wide range of workpiece materials. A built-in coolant-through port (1/4-18 NPT thread) supports directed coolant delivery at the cutting edge. Installed by machinists and tool-room technicians in production and job-shop environments.

This boring bar is suited for internal diameter finishing and semi-finishing passes in both ferrous and non-ferrous materials. The right-hand cut orientation fits standard lathe spindle rotation in conventional turning setups. The 1-inch shank fits common VDI, rectangular, or round-bore tool blocks used on most CNC turning centers and manual lathes equipped with appropriate boring bar holders. The screw-clamp insert-holding method delivers secure seating under interrupted cuts and moderate feeds. Coolant-through capability makes it practical for deeper bore applications where chip evacuation and heat management are priorities.

Key Features

• A16SCFPR3 toolholder style with right-hand cut orientation
• Screw-clamp insert retention for secure, repeatable CP-style insert seating
• Coolant-through design with 1/4-18 NPT coolant port for direct cutting-zone cooling
• Neutral rake (0 degrees) geometry for broad material compatibility
• Steel body construction with 1-inch shank diameter
• Insert inscribed circle: 3/8 inch; insert thickness: 5/32 inch

Compatibility

Accepts CP-style indexable inserts with a 3/8-inch inscribed circle and 5/32-inch thickness. Fits tool blocks and boring bar holders sized for a 1-inch round shank.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the machine spindle before mounting or changing inserts. Seat the shank fully in the tool block and torque the clamping screws to the holder manufacturer specification. Connect coolant supply to the 1/4-18 NPT port before initiating coolant-through operation, and verify there are no leaks prior to running the spindle.
