Sandvik Coromant 5749486 Indexable Turning Toolholder

Product Description

The SANDVIK COROMANT 5749486 is a left-hand indexable turning toolholder in the SDJCL163D style, designed for external turning and facing operations on CNC lathes and turning centers. It features a screw-clamp insert holding method with a neutral rake angle of 0 degrees, providing stable, repeatable cutting geometry. The toolholder accepts DCMT 32.52 inserts with a 3/8-inch inscribed circle. The shank measures 1 inch wide by 1 inch tall, and the overall length is 6 inches. At 1.68 pounds, it suits both production and job-shop turning environments. This holder is part of the CoroTurn 107 series and is installed by machinists and CNC tooling technicians.

This toolholder is suited for facing and external turning applications in light to medium cutting conditions. It is commonly mounted in gang-tool setups, turret lathes, and CNC turning centers where consistent insert indexing and minimal setup time are priorities. The left-hand orientation directs cutting forces toward the spindle on specific workholding configurations. The multi-use designation indicates it can be adapted across a range of turning profiles within its insert compatibility range. Machine shops running production runs or prototype work both benefit from the tool-change efficiency the screw-clamp system provides.

Installation Notes

Installation is performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before mounting or indexing any toolholder. Seat the shank fully in the turret or tool block and torque all mounting screws to the machine or tooling manufacturer specifications. Use the correct Torx or hex key for the insert clamping screw and verify insert seating before resuming cutting operations.
