Sandvik Coromant 7968154 Boring Bar 4 Mm Shank

Product Description

The SANDVIK COROMANT 7968154 is a compact boring bar designed for precision internal turning and bore finishing operations on CNC lathes and machining centers. With a 4.00 mm shank diameter and a 27.25 mm overall length, this bar is suited for small-bore applications where access and dimensional control are critical. The compact geometry allows operation in tight bore entries where larger tooling cannot reach. Machinists and toolroom technicians select this bar for fine finishing passes and light material removal in small-diameter bores requiring tight tolerances.

This boring bar is intended for use in small-bore internal turning applications on CNC turning centers and manual lathes equipped with appropriate toolholding. The 4.00 mm shank diameter makes it appropriate for micro-boring and precision finishing work on components such as hydraulic bodies, valve housings, and instrumentation parts. It is packaged individually and suited for both production and job-shop environments where small-bore accuracy is required.

Key Features

• 4.00 mm shank diameter engineered for small-bore internal turning applications
• 27.25 mm overall length provides a compact profile for restricted bore entries
• Designed for precision finishing passes requiring tight dimensional control
• Individual packaging ensures tooling integrity at point of use
• UNSPSC Code 23241601 for streamlined procurement classification

Compatibility

Designed as an OEM-style replacement boring bar for use in CNC turning centers and manual lathes with toolholding systems sized to accept a 4.00 mm shank diameter boring bar.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and all power is isolated before mounting or removing tooling. Secure the shank fully within the toolholder to the manufacturer-specified clamping depth to prevent deflection or pullout during cutting. Confirm bore entry clearance before initiating a cut to avoid tool or workpiece damage.
