Sandvik Coromant 5735522 Indexable Boring Bar 1/2 in Shank

Product Description

The SANDVIK COROMANT 5735522 is a solid carbide indexable boring bar in the CoroCut MB series, designed for internal turning and boring operations on CNC lathes and machining centers. It carries a neutral cut geometry and accepts MB-09 style inserts, which are sold separately. The shank diameter is 0.5 inches (12.70 mm) and the overall length is 4.3307 inches (110 mm). Coolant-through capability delivers cutting fluid directly to the insert tip, supporting chip evacuation and extended tool life in difficult materials. This bar is a precision tool intended for machinists and toolroom professionals in production and job-shop environments.

This boring bar is suited for finish and semi-finish boring of small-diameter bores starting at 0.5 inches (12.70 mm) minimum bore diameter. The maximum bore depth reaches 41.70 mm. Its solid carbide construction provides rigidity and vibration resistance in slender-bore applications where chatter control is critical. Typical installations include CNC turning centers and live-tool lathes in both production shops and precision job shops. The CoroCut MB system is a dedicated small-part and back-boring platform.

Key Features

• Solid carbide body for superior rigidity and vibration damping in small-bore applications
• Neutral cut orientation accommodates standard insert indexing in confined bore geometries
• Coolant-through design directs fluid to the cutting zone for improved chip control and insert life
• Accepts MB-09 inserts — inserts not included, ordered separately
• Minimum bore diameter of 0.5 inches (12.70 mm) with a maximum bore depth of 41.70 mm
• Overall length of 4.3307 inches (110 mm) with a 0.5 inch (12.70 mm) shank diameter

Compatibility

Designed for use with MB-09 series inserts within the SANDVIK COROMANT CoroCut MB tooling system. Compatible with any machine tool spindle or turret accepting a 0.5 inch straight shank boring bar.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and the CNC program is in a safe state before mounting or removing the boring bar. Secure the shank in a compatible boring bar holder or turret block to the machine manufacturer's specified clamping torque using appropriate toolholder hardware. Verify coolant-through passages are clear and that the insert is properly seated and locked before resuming cutting operations.
