Kennametal 1950382 Indexable Boring Bar Right Hand

Product Description

The KENNAMETAL 1950382 is an indexable boring bar designed for precision internal turning operations on CNC lathes and machining centers. Built with a solid carbide shank and steel head, this right-hand-cut toolholder accepts WP-style inserts secured by screw clamping. It features a 3-degree lead angle with neutral rake geometry, a minimum bore diameter of 0.347 inches, and an overall length of 6 inches. Coolant-through capability via a 0.093-inch coolant hole diameter supports chip evacuation and thermal management during tight-bore applications. This bar is installed and set up by machinists and tooling technicians working in precision machining environments.

This boring bar is suited for small-diameter internal boring where access and rigidity are critical. The 5/16-inch shank diameter and 0.347-inch minimum bore capability make it appropriate for fine-bore work in both production and job-shop settings. It is compatible with standard toolholding systems that accept 5/16-inch round shanks. The maximum bore depth of 3.12 inches allows for moderately deep passes without tool deflection concerns common to longer overhangs.

Key Features

• Solid carbide shank provides superior rigidity and vibration damping compared to steel-shank alternatives
• Coolant-through design with 0.093-inch coolant hole supports chip flushing in blind and deep bores
• Screw-clamp insert holding method ensures repeatable insert indexing and secure cutting edge retention
• Neutral rake, 3-degree lead angle geometry suits a broad range of workpiece materials
• Right-hand cut orientation for standard lathe and boring mill setups
• Accepts WP-style inserts with 0.187-inch inscribed circle for availability and versatility

Compatibility

Designed for use with WP-style inserts. Toolholder style is GCBIW within the G Series. No specific machine model compatibility was provided in the product data.

Installation Notes

This toolholder is installed by qualified machinists or toolroom technicians. Power down and lock out the machine spindle before inserting or indexing cutting inserts. Use the appropriate Torx or hex key as specified by the insert screw to avoid stripping the clamp screw. Verify shank runout and boring bar alignment before initiating a cut to prevent premature insert wear or workpiece damage.
