Sandvik Coromant 5747996 Indexable Boring Cartridge

Product Description

The SANDVIK COROMANT 5747996 is a right-hand indexable boring cartridge in the CoroBore 825 series, designed for precision finishing operations on CNC boring systems. The cartridge accepts TPMT 221 inserts and supports a minimum bore diameter of 2.1654 inches (55.00 mm). At 1.3701 inches overall length and Cartridge Size 3, it is built for controlled, repeatable cutting geometry in tight-tolerance bores. Machinists and tooling technicians working in production or job-shop environments install this cartridge as part of a modular boring setup where indexable tooling reduces changeover time and maintains consistent surface finish.

This cartridge is suited for finishing-pass boring applications in metalworking environments. It is intended for use in modular CoroBore 825 boring systems where cartridge-style tooling allows fine diameter adjustment. Typical applications include finishing bores in ferrous and non-ferrous workpieces where tight dimensional tolerances and surface quality are required. The right-hand cutting direction makes it compatible with standard spindle rotation in the majority of horizontal and vertical machining centers.

Key Features

• Minimum bore diameter of 2.1654 inches (55.00 mm) for finishing-range applications
• Right-hand cutting direction for compatibility with standard spindle rotation
• Accepts TPMT 221 indexable inserts for fast, repeatable edge changes
• Cartridge Size 3 fits CoroBore 825 series modular boring systems
• Toolholder style R825..AF..T..P for precise cartridge seating and adjustment
• Compact 1.3701-inch overall length supports use in confined bore depths

Compatibility

Designed for use in the CoroBore 825 modular boring system. Compatible insert style is TPMT, with complete insert compatibility confirmed for TPMT 221.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician with the machine spindle fully stopped and the control placed in a safe, locked-out state. Secure the cartridge to the boring head body according to the boring system manufacturer's torque guidance for the applicable cartridge size. Verify insert seating and cartridge clamping before resuming machine operation. Inspect cartridge and insert contact surfaces for debris or damage prior to each setup.
