Sandvik Coromant 5731604 Indexable Boring Bar Solid Carbide

Product Description

The SANDVIK COROMANT 5731604 is a solid carbide indexable boring bar from the CoroTurn 111 series, designed for internal boring and turning operations on small-diameter workpieces. It features a right-hand cut orientation and a screw clamping insert holding method that secures WPMT 1.210 inserts firmly during aggressive cuts. The shank diameter is 3/16 inches (4.76 mm) and the overall length is 4 inches (101.60 mm). With a minimum bore diameter of 0.2598 inches (6.60 mm), this bar is built for tight-tolerance small-bore work in production and job shop environments. Coolant-through capability supports chip evacuation and tool life in demanding applications.

This boring bar is suited for CNC turning centers and live-tool lathes performing internal diameter operations in small bores. The CoroTurn 111 platform is designed for small-part machining where access is limited and bore diameter control is critical. The neutral rake angle (0 degrees) and screw clamping system make it a dependable choice for machinists running both boring and turning operations from a single toolholder. It accepts one insert per holder and is rated for multi-use applications.

Key Features

• Solid carbide construction for rigidity and vibration resistance in small-bore applications
• Coolant-through design aids chip flushing and extends insert life
• Screw clamping insert retention provides secure, repeatable insert indexing
• Neutral rake angle (0 degrees) supports stable cutting across a range of materials
• Compatible with WPMT 1.210 inserts with a 0.150-inch inscribed circle
• Multi-use toolholder supports both boring and turning operations

Compatibility

Designed for use with WPMT 1.210 inserts (inscribed circle 0.150 inches / 3.81 mm). Part of the SANDVIK COROMANT CoroTurn 111 series platform for small-part internal machining.

Installation Notes

Installation should be performed by a qualified machinist following standard toolholder setup procedures for CNC turning equipment. Secure the shank in a collet or boring bar holder rated for 3/16-inch shanks and verify runout before cutting. Power down the machine and follow lockout/tagout procedures before changing inserts or adjusting the toolholder. Do not exceed the minimum bore diameter of 0.2598 inches to avoid tool deflection or insert damage.
