Kennametal 1094719 Indexable Boring Bar 5/8 in Shank

Product Description

The KENNAMETAL 1094719 is a steel indexable boring bar designed for internal turning and boring operations on CNC lathes and manual turning centers. Built to the A-SVQB toolholder style, it accepts VB-style screw-clamped inserts and delivers a neutral rake angle for balanced cutting performance. The right-hand cutting orientation and -17.5-degree lead angle make it suited for standard bore entry profiles. With a 5/8-inch shank diameter and 10-inch overall length, it fits a wide range of tool turrets and boring bar holders common in production and job-shop turning environments. A coolant-through design with a 1/8-27 NPT coolant hole thread supports chip evacuation and tool life in demanding materials. Licensed machinists and CNC turning technicians are the primary installers.

This boring bar is used in ferrous and non-ferrous internal boring applications where a minimum bore diameter of 0.850 inches (21.59 mm) can be achieved. Its screw-clamp insert retention provides positive indexing for repetitive production runs. The 10-inch OAL allows reach into deeper bores while maintaining rigidity with the 5/8-inch steel shank. Typical applications include finish and semi-finish boring on turned components in aerospace, automotive, and general machining environments.

Key Features

• Minimum bore diameter of 0.850 inches (21.59 mm) for tight bore entry capability
• Right-hand cut orientation with -17.5-degree lead angle
• Screw-clamp insert holding for positive, repeatable indexing using VB-style inserts
• Coolant-through design with 1/8-27 NPT coolant hole thread for chip flushing and thermal control
• Neutral rake (0-degree rake angle) for broad material compatibility
• Steel construction with 5/8-inch shank diameter and 10-inch overall length
• 1/4-inch insert inscribed circle; 1/8-inch insert thickness

Compatibility

Accepts VB-style inserts with a 1/4-inch inscribed circle and 1/8-inch thickness. Designed for use in tool turrets and boring bar holders that accept a 5/8-inch round shank, consistent with A-SVQB toolholder style boring bars used on CNC and manual turning centers.

Installation Notes

Installation is performed by a machinist or CNC turning technician. The machine spindle must be fully stopped and the turret de-energized before mounting or indexing inserts. Shank clamping torque should follow the machine tool manufacturer specifications for 5/8-inch boring bar holders. Verify coolant line connection at the 1/8-27 NPT port before initiating a coolant-through cycle to prevent unintended fluid discharge.
