Kennametal 1096419 Indexable Boring Bar 1-1/2 in Shank

Product Description

The KENNAMETAL 1096419 is a steel indexable boring bar designed for internal turning and boring operations on CNC lathes and machining centers. Built to the A-MCLN toolholder style, this right-hand-cut bar accepts CN-style inserts held by screw or clamp, supporting a negative rake geometry with a -5 degree lead angle. The shank diameter is 1.5 inches (38.10 mm) and the overall length is 14.0 inches (355.60 mm). Part of the Kenloc series, this bar is suited for machinists and tooling technicians running production or jobshop bore work where rigid, repeatable insert clamping is required.

This boring bar covers a minimum bore diameter of 1.76 inches (44.70 mm), making it appropriate for medium to large bore applications in steel, cast iron, and similar materials. The coolant-through design with a 1/4-18 NPT coolant hole supports chip evacuation and thermal management during interrupted or continuous cuts. Typical installations include horizontal and vertical turning centers in production machining environments where consistent bore finish and dimensional accuracy are priorities.

Key Features

• Minimum bore diameter of 1.76 inches (44.70 mm) for medium to large bore work
• Right-hand cut, A-MCLN toolholder style with negative rake at -5 degrees lead angle
• Accepts CN-style inserts (1/2-inch inscribed circle, 3/16-inch thickness) via screw or clamp holding
• Coolant-through capability with 1/4-18 NPT coolant hole thread for improved chip control
• Steel construction, 14.0-inch overall length for extended reach in deep bore setups
• Kenloc series design for consistent insert indexing and clamping rigidity

Compatibility

Designed to accept CN-style inserts with a 1/2-inch inscribed circle and 3/16-inch thickness, compatible with standard Kenloc series tooling systems. Insert holding is via screw or clamp method as specified by the A-MCLN toolholder style.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and locked out before mounting or adjusting the boring bar. The bar must be properly torqued into the tool turret or holder per the machine tool manufacturer specifications — do not overtighten the insert clamp screw beyond the insert manufacturer recommendation. Verify coolant line connection to the 1/4-18 NPT port before resuming operation to prevent thermal damage to the insert and workpiece.
