Kennametal 1096474 Indexable Boring Bar 1 in Shank

Product Description

The KENNAMETAL 1096474 is a right-hand A-MWLN indexable boring bar designed for internal turning and precision bore finishing in metal cutting applications. Built from steel with a 1-inch (25.40 mm) shank diameter and a 12-inch overall length, this boring bar accepts WN-style inserts held securely by a screw and clamp method. The tool operates with a negative rake angle of 5 degrees and a lead angle of -5 degrees, making it well suited for stable cutting in tight bore conditions. Through-coolant capability is supported via a 1/4-18 NPT coolant hole, helping to manage heat and chip evacuation during continuous cuts.

This boring bar is intended for use in CNC lathes and turning centers where precision internal diameter work is required. It is suited for production machining environments in metalworking shops, tool rooms, and manufacturing facilities. The 30.48 mm (1.200 inch) minimum bore diameter defines the smallest bore this tool can effectively reach. It is part of the Kennametal Kenloc series, a line built around reliable insert retention and repeatable tool positioning for high-volume and precision boring operations.

Key Features

• A-MWLN toolholder style accepts WN-series indexable inserts with 3/8-inch inscribed circle
• Through-coolant design with 1/4-18 NPT threaded coolant port for chip flushing and heat control
• Screw and clamp insert holding method for secure retention under cutting loads
• Negative rake geometry at 5 degrees with -5 degree lead angle for stable boring performance
• 1-inch shank diameter and 12-inch overall length suits standard lathe and turning center tooling blocks
• Steel construction provides rigidity and durability in continuous cutting operations

Compatibility

Designed for use with WN-style indexable inserts with a 3/8-inch inscribed circle and 3/16-inch insert thickness, following the A-MWLN toolholder standard. Part of the Kennametal Kenloc series.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Secure the shank fully in the boring bar holder or turret block before operation and verify that insert seating and clamping torque meet the toolholder manufacturer guidelines. Connect the coolant supply line to the 1/4-18 NPT port before starting the spindle when through-coolant is in use. Confirm minimum bore clearance of 30.48 mm before engaging the cutting edge to avoid tool or workpiece damage.
