Kennametal 1094675 Indexable Boring Bar 5/8 Inch Shank

Product Description

The KENNAMETAL 1094675 is a steel indexable boring bar designed for internal turning and boring operations on CNC lathes and manual turning centers. It carries the toolholder style designation A10SCLPR3 and features a 5/8 inch (15.88 mm) shank diameter with a 10 inch (254 mm) overall length. The bar accepts CP-style inserts secured by a screw clamping method, providing consistent insert location and repeatable cutting performance. A built-in coolant-through port with a 1/8-27 NPT thread allows directed coolant delivery to the cutting zone, helping manage heat and chip evacuation during deep bore operations. Licensed machinists and CNC turning technicians install this tool in standard boring bar holders or turret tooling blocks.

This boring bar is suited for finish and semi-finish internal boring in steel, cast iron, and similar materials where a right-hand cutting, neutral-rake geometry is appropriate. The minimum bore diameter is 0.770 inch (19.56 mm), making it applicable to relatively tight bore diameters in production turning environments. The -5 degree lead angle geometry affects the direction of cutting forces and chip flow, which should be factored into setup planning. It is appropriate for both manual and CNC turning applications in job shop and production floor settings.

Key Features

• Minimum bore diameter of 0.770 inch (19.56 mm) for tight-bore internal turning
• 5/8 inch (15.88 mm) shank diameter, 10 inch (254 mm) overall length for extended reach
• Screw-clamp insert holding method for secure, repeatable insert indexing
• Coolant-through capability via 1/8-27 NPT port for in-cut cooling and chip control
• Neutral rake angle (0 degrees) suitable for a broad range of work materials
• Right-hand cut orientation; -5 degree lead angle for controlled axial force direction

Compatibility

Accepts CP-style inserts with a 3/8 inch inscribed circle and 5/32 inch insert thickness. Insert holding is by screw clamp. Confirm insert grade and geometry selection against the specific work material and cutting parameters before installation.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and the turret or tool post is in a safe, locked state before mounting or removing the boring bar. The bar must be clamped securely with adequate shank engagement in the holder to minimize overhang-related vibration. Verify coolant line connections to the 1/8-27 NPT port are leak-free before running the machine.
