Sandvik Coromant 5735525 Indexable Boring Bar 1/2 in Rh

Product Description

The SANDVIK COROMANT 5735525 is a solid carbide indexable boring bar in the CoroCut MB series, designed for internal turning and bore finishing operations on CNC lathes and machining centers. With a minimum bore diameter of 0.5 inches (12.70 mm) and an overall length of 4.374 inches (111.10 mm), this right-hand-cut toolholder delivers rigid, accurate performance in small-bore applications. It accepts MB-07 inserts and features through-coolant capability, which helps extend insert life and evacuate chips from tight bore geometries. The shank diameter is 0.5 inches (12.70 mm), matching the minimum bore diameter for close-clearance work. Inserts are not included.

This boring bar is suited for precision internal machining in production and job-shop environments. The CoroCut MB system is commonly applied in high-precision bore work on ferrous and non-ferrous materials where tight tolerances and consistent surface finish are required. The through-coolant feature makes it particularly effective in deep-bore or high-speed applications where heat and chip management are critical. It is used by machinists and CNC operators on turning centers and mill-turn machines where a 0.5 inch shank interface is specified.

Key Features

• Minimum bore diameter of 0.5 inches (12.70 mm) for small-bore internal turning
• Right-hand cut orientation for standard turning center setup
• Solid carbide construction for rigidity and vibration resistance in small overhangs
• Through-coolant capability for chip evacuation and thermal control
• Compatible with MB-07 series inserts for quick, repeatable edge changes
• Maximum bore depth of 48.00 mm for versatile reach in confined bores

Compatibility

Accepts MB-07 series inserts. Part of the CoroCut MB toolholder system. Inserts are not included and must be ordered separately.

Installation Notes

Installation and setup should be performed by a qualified CNC machinist or tooling technician. Ensure the machine spindle and turret are fully powered down and locked out before mounting or removing the toolholder. Confirm shank clamping torque and coolant port alignment per the machine tool specification before engaging the through-coolant supply. Follow the insert manufacturer guidelines when seating MB-07 inserts to avoid damage to the insert pocket or clamping screw.
