Kennametal 1094699 Indexable Boring Bar 3/4 in Shank

Product Description

The KENNAMETAL 1094699 is a steel indexable boring bar designed for internal turning and boring operations on CNC lathes and machining centers. It carries the toolholder style designation A-SVSP and accepts VB-series inserts secured by a screw clamping method. The shank diameter measures 3/4 inches (19.05 mm) with an overall length of 10 inches (254 mm). Minimum bore diameter is 0.980 inches (24.89 mm), making it suited for small-to-mid-range bore work. The neutral rake angle of 0 degrees and a lead angle of -3 degrees define the cutting geometry. A coolant-through design with a 1/8-27 NPT coolant hole thread supports chip evacuation and tool life in production environments. Machinists and tool-and-die professionals install and set this bar.

This boring bar fits standard lathe and turning center setups where a 3/4-inch round shank tool station is available. It is intended for right-hand cut operations. The screw-lock insert retention and neutral rake geometry make it appropriate for a range of ferrous and non-ferrous materials depending on the insert grade selected. It is a single-purpose tool (not multi-use) and is sold individually. Typical applications include finish and semi-finish internal diameter turning in job-shop and production machining environments.

Key Features

• Steel construction shank for rigidity in boring applications
• Screw-clamp insert retention for secure, repeatable insert indexing
• Coolant-through design with 1/8-27 NPT thread for directed coolant delivery
• Neutral rake (0 degrees) with -3 degree lead angle for controlled cutting geometry
• Accepts VB-series inserts with 1/4-inch inscribed circle and 1/8-inch thickness
• Right-hand cut orientation for standard lathe spindle direction

Compatibility

Designed to accept VB-series indexable inserts with a 1/4-inch inscribed circle and 1/8-inch insert thickness, secured via screw clamping. Toolholder style is A-SVSP. Verify insert grade and geometry selection against workpiece material and machine specifications before use.

Installation Notes

Installation is performed by a qualified machinist or tooling technician. Power down and lock out the machine spindle before mounting or removing the boring bar from the tool turret or boring bar holder. Secure the 3/4-inch shank to the specified clamping torque called out in the machine tool manual. Follow the insert manufacturer guidelines for insert indexing and replacement, and confirm coolant line connection to the 1/8-27 NPT port before resuming operation.
