Sandvik Coromant 5733413 Grooving Toolholder LF123G079-12B

Product Description

The SANDVIK COROMANT 5733413 is an indexable grooving and cutoff toolholder designated style LF123G079-12B, part of the CoroCut 1-2 series. Designed for external grooving, parting, and cut-off operations, this left-hand toolholder accepts N123G2-0300-CM inserts secured by a clamp-style insert holding method. It supports groove widths from 3.00 mm to 4.00 mm and delivers a maximum depth of cut of 20.07 mm (0.79 inches). The 3/4 x 3/4 inch shank fits standard toolpost setups on CNC lathes and turning centers. This toolholder is installed by machinists and CNC turning specialists working in production or job-shop environments.

The LF123G079-12B toolholder is suited for external grooving and parting applications on CNC turning machines. Its left-hand orientation positions it for specific spindle and turret configurations where right-hand holders are not appropriate. The CoroCut 1-2 series is engineered for precise, repeatable groove geometry in both roughing and finishing passes. Compatible insert N123G2-0300-CM is used for groove widths at the 3.00 mm end of the specified range. This toolholder is appropriate for use on ferrous and non-ferrous workpieces in both light and moderate cutting conditions.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Power down and lockout the machine before mounting or removing the toolholder from the turret or toolpost. Secure the shank to the correct torque specification per your machine tool manufacturer guidelines using appropriate toolholder clamp hardware. Do not exceed the rated maximum depth of cut or overhang, as doing so may cause insert breakage or toolholder damage.
