Sandvik Coromant 5740954 Grooving Toolholder RF151.23-12-30

Product Description

The SANDVIK COROMANT 5740954 is an indexable grooving and cutoff toolholder designed for external turning operations on CNC lathes and turning centers. Built to the RF151.23-12-30 style, it accepts N151.2-300-5E inserts secured by a clamp-style insert holding method, delivering consistent edge positioning across repeated insert changes. The toolholder handles groove widths from 3.00 millimeters to 4.15 millimeters and supports a maximum depth of cut of 20.07 millimeters (0.79 inches). The right-hand configuration and 3/4 inch square shank suit standard OD turning setups where precise groove geometry and reliable insert clamping are required. It weighs 0.71 pounds.

This toolholder is intended for external grooving and parting-off applications in production and job-shop environments. It fits lathes and turning centers accepting a 3/4 inch by 3/4 inch shank. The T-Max Q-Cut series design is oriented toward consistent groove width control in ferrous and non-ferrous workpiece materials. Licensed machinists and CNC operators working on precision turned components will find this holder well-suited for repetitive grooving cycles where insert changeover speed and dimensional repeatability matter.

Installation Notes

Installation should be performed by a qualified machinist or CNC technician with the machine powered off and the spindle locked before toolholder mounting or insert replacement. The shank must be clamped securely in a properly sized tool block or turret station, with adequate clamping engagement along the shank length to prevent deflection under cutting loads. Always follow the machine tool manufacturer torque and clamping recommendations for turret tooling. Verify insert seating and clamp condition before resuming cutting operations.
