Sandvik Coromant 5747994 Indexable Boring Cartridge

Product Description

The SANDVIK COROMANT 5747994 is an indexable boring cartridge designed for precision finishing operations in boring applications. Part of the CoroBore 825 series, this right-hand cutting cartridge accepts TCMT-style inserts, specifically the TCMT 221, allowing for repeatable, accurate bore finishes. With a minimum bore diameter of 2.1654 inches (55.00 mm) and an overall length of 1.3701 inches, this cartridge is built for tight-tolerance internal diameter work. It is installed by machinists and tooling technicians in CNC turning and boring setups where consistent insert replacement and reliable geometry are required.

This cartridge fits finishing applications on CNC lathes and boring machines where the CoroBore 825 modular boring system is in use. It is suited for shops performing high-accuracy internal diameter finishing on medium to large bore diameters. The right-hand cutting direction makes it appropriate for standard spindle rotation setups. Compatible insert style is TCMT, with full compatibility confirmed for the TCMT 221 insert designation as specified by the manufacturer.
