Sandvik Coromant 7968157 Boring Bar 4.00mm Shank

Product Description

The SANDVIK COROMANT 7968157 is a precision boring bar designed for internal machining operations requiring tight dimensional control. With a 0.157-inch shank diameter and an overall length of 1.073 inches, this is a compact tooling solution suited for small-bore applications on lathes, machining centers, and CNC turning equipment. Machinists and tooling specialists working with fine-tolerance bores rely on boring bars of this type to achieve accurate diameter and surface finish in production and job-shop environments. The part ships individually and is available in single-unit quantities.

This boring bar is applicable in precision metal-cutting operations where small shank diameters are required. It is suited for use in CNC turning centers, Swiss-type lathes, and multi-axis machining platforms handling small-diameter internal features. Typical users include machinists, toolroom technicians, and production shops working with ferrous and non-ferrous materials requiring controlled bore geometry.

Key Features

• Compact 4.00 mm (0.157-inch) shank diameter for small-bore internal machining
• 27.25 mm (1.073-inch) overall length provides a minimal footprint in tight tooling setups
• Lightweight at 0.04 pounds, minimizing spindle load in sensitive applications
• Single-unit packaging supports individual replacement without excess inventory
• UNSPSC Code 23241601 classification for procurement and catalog integration

Compatibility

Designed as an OEM-style replacement boring bar for small-shank internal machining toolholders and systems accepting a 4.00 mm shank diameter.

Installation Notes

Installation of boring bars should be performed by a qualified machinist or tooling technician with the machine powered down and locked out per applicable safety procedures. Ensure the shank is fully seated and secured in the toolholder before resuming operation. Verify bore alignment and runout with a dial indicator before taking a finish pass. Follow the machine tool manufacturer guidelines for maximum overhang and cutting parameters for this shank diameter class.
