Sandvik Coromant 5734223 Indexable Boring Bar Left Hand

Product Description

The SANDVIK COROMANT 5734223 is a solid carbide indexable boring bar from the CoroTurn 107 series, designed for internal turning and precision bore finishing operations. It features a left-hand cut orientation, a 3/8-inch shank diameter, and a minimum bore diameter of 0.4803 inches (12.20 mm). The toolholder uses screw clamping to secure a single CCMT 21.51 insert, providing secure, repeatable cutting edge positioning. At 6 inches overall length, this bar suits CNC turning centers and manual lathes where tight bore tolerances are required. Licensed machinists and CNC operators in production and job-shop environments are the primary users of this type of tooling.

This boring bar fits applications requiring left-hand internal turning in small-diameter bores. The CoroTurn 107 series is engineered for light to medium cutting depths in steel, stainless, cast iron, and non-ferrous materials. The neutral rake angle (0 degrees) and a center-to-cutting-edge distance of 0.25 inches allow consistent chip formation across a range of bore depths. Coolant-through capability makes it suitable for deep-bore applications where chip evacuation and tool-life management are priorities. Both production shops and toolrooms running tight-tolerance bore work will find this bar applicable to their operations.

Key Features

• Solid carbide construction provides rigidity and vibration resistance in small-diameter boring applications
• Left-hand cut orientation for specific machine setups and back-boring configurations
• Screw clamping insert retention for secure, repeatable CCMT 21.51 insert indexing
• Coolant-through design supports chip evacuation in deeper bore depths
• Neutral rake angle (0 degrees) compatible with a broad range of workpiece materials
• CoroTurn 107 series toolholder style (E-SCLC) for consistent geometric performance

Compatibility

This toolholder accepts CCMT 21.51 inserts with a 1/4-inch inscribed circle. It is designed as an OEM-style replacement or direct-use boring bar for CNC turning centers and manual lathes equipped with 3/8-inch tool station bores and requiring left-hand internal turning capability.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Power down and lock out the machine spindle before mounting or removing the toolholder. Ensure the shank seating surface and tool station bore are clean and free of chips before clamping. Follow the machine tool manufacturer's torque specifications for tool clamping hardware, and verify insert seating before running the spindle.
