Sandvik Coromant 5732367 Indexable Boring Bar Solid Carbide

Product Description

The SANDVIK COROMANT 5732367 is a solid carbide indexable boring bar from the CoroTurn 107 series, designed for precision internal boring and turning operations on CNC lathes and turning centers. The bar features a 1/2-inch shank diameter, a minimum bore diameter of 0.5984 inches (15.20 mm), and an 8-inch overall length. Screw clamping secures a single TCMT 221 insert at a neutral rake angle, providing consistent cutting geometry across both boring and turning applications. Through-coolant capability supports chip evacuation and tool life in demanding cuts.

This boring bar is suited for right-hand internal machining in precision turning environments, including aerospace, die and mold, and general metalworking shops. It accepts TCMT 221 triangular inserts with a 1/4-inch inscribed circle diameter. The E-STFC toolholder style positions the cutting edge 0.3120 inches from center and extends back-of-bar to cutting edge at 8.0000 inches, making it appropriate for moderate-depth bores requiring a rigid, vibration-resistant solid carbide body. Both boring and turning operations are supported with this toolholder.

Key Features

• Solid carbide body provides rigidity and vibration damping in small-bore applications
• Minimum bore diameter of 0.5984 inches (15.20 mm) for tight-diameter internal work
• Through-coolant design aids chip removal and extends insert life
• Screw clamping insert retention for secure, repeatable insert indexing
• Neutral rake angle (0 degrees) and 0-degree lead angle for balanced cutting forces
• Multi-use capability supports both boring and turning operations

Compatibility

Designed for use with TCMT 221 inserts featuring a 1/4-inch (6.35 mm) inscribed circle and 1/8-inch insert thickness. Part of the CoroTurn 107 series and compatible with E-STFC style toolholder systems requiring a 1/2-inch shank diameter.

Installation Notes

Installation is performed by qualified machinists or tooling technicians on CNC lathes or turning centers. Ensure the machine spindle is fully stopped and the turret is in a safe index position before mounting or changing inserts. Verify that the boring bar shank is clamped squarely and to the full recommended engagement depth in the turret block before initiating cuts. Follow the insert manufacturer torque guidelines for screw clamping during insert indexing.
