Sandvik Coromant 5727601 Indexable Boring Bar 1 in Shank

Product Description

The SANDVIK COROMANT 5727601 is a steel indexable boring bar from the T-Max P series, designed for internal boring and turning operations on CNC lathes and turning centers. It carries a single CNMG 432 insert secured by a wedge-style clamping mechanism, delivering consistent cutting forces and reliable insert seating under demanding material removal conditions. The toolholder has a 1-inch shank diameter, a 12-inch overall length, and a minimum bore diameter of 1.28 inches (32.51 mm). With a negative rake angle of -6 degrees and a right-hand cut orientation, this bar suits a wide range of ferrous and non-ferrous boring applications where dimensional accuracy and tool rigidity are required.

This boring bar is suited for production and job-shop environments running internal diameter work on lathes and turning centers. Its multi-use design supports both boring and turning applications from a single toolholder body. The coolant-through capability makes it a practical choice for deep-bore work where chip evacuation and heat management at the cutting zone are critical. A licensed machinist or CNC turning specialist typically sets up and qualifies this toolholder. It is a direct-fit, OEM-style toolholder for shops already running CNMG 432-family inserts.

Key Features

• Wedge-style insert clamping for secure seating and repeatable insert indexing
• Coolant-through design supports chip evacuation in deep-bore applications
• Negative rake geometry (-6 degrees) provides strength and stability for interrupted and continuous cuts
• Multi-use toolholder rated for both boring and turning operations
• Right-hand cut orientation for standard spindle direction setups
• Steel toolholder body balances rigidity and vibration damping for precision internal work

Compatibility

Designed to accept CNMG 432 inserts with a 1/2-inch inscribed circle. Compatible with standard 1-inch round shank toolholder pockets on CNC lathes and turning centers. Multi-use application covers boring and turning.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. Power down and lock out the machine spindle before mounting or removing the toolholder. Verify shank clamp torque against machine manufacturer specifications and confirm insert seating and wedge clamp engagement before running the spindle. Do not exceed the machine tool manufacturer's recommended overhang-to-diameter ratio for this shank size, as excessive overhang increases the risk of chatter and tool deflection.
