Sandvik Coromant 5749557 Indexable Turning Toolholder

Product Description

The SANDVIK COROMANT 5749557 is a left-hand indexable turning toolholder in the SDJC style, part of the CoroTurn 107 series. It accepts DCMT 11 T3 08 inserts secured by a screw clamping method, providing a stable and repeatable cutting setup on CNC lathes and manual turning centers. The toolholder features a neutral rake angle of 0 degrees and a 0.5 inch square shank, making it suitable for external turning operations where a left-hand cutting direction is required. The steel body delivers the rigidity needed for consistent chip control and dimensional accuracy across production turning applications. This toolholder is installed by machinists and CNC operators in precision metalworking environments.

The 5749557 is designed for external turning operations on CNC lathes and turning centers where left-hand tool orientation is needed. It is a single-use toolholder, not rated for multi-use or driven applications. The SDJC style geometry directs cutting forces appropriately for finishing and semi-finishing passes. The 0.5 inch square shank fits standard tool blocks and turret stations commonly found in light to medium-duty turning setups. Insert changes are fast and repeatable using the screw-clamp method, reducing downtime during production runs.

Compatibility

Compatible with DCMT 11 T3 08 series inserts. Designed as an OEM-style replacement toolholder for CoroTurn 107 series turning setups requiring a left-hand SDJC-style holder with a 1/2 inch square shank.

Installation Notes

Installation is performed by a qualified machinist or CNC operator. Ensure the lathe or turning center is fully powered down and the turret is locked before mounting or removing the toolholder. Seat the shank fully in the tool block and torque the clamping screws according to the machine tool manufacturer specifications. Verify insert seating and tool overhang before resuming cutting operations.
