Sandvik Coromant 5739169 Grooving Cutoff Toolholder Right Hand

Product Description

The SANDVIK COROMANT 5739169 is an indexable grooving and cutoff toolholder in the CoroCut XS series, designed for external grooving, parting, and cut-off operations on CNC lathes and turning centers. It uses a QS-SMALR083X style head with a clamp-style insert holding method, accepting MAxR 3.. inserts with a compatible insert size code of MACR 3 200. The toolholder features a 0.5-inch square shank and delivers a maximum depth of cut of 0.335 inches (8.5 mm). It is a right-hand configuration intended for professional machining environments where precise, repeatable grooving performance is required.

This toolholder is suited for external grooving and parting applications on turning centers and CNC lathes. The CoroCut XS series is built for small-part machining and Swiss-style turning environments where compact tooling with rigid insert clamping is essential. The QS quick-change shank interface allows fast, repeatable tool changes without resetting offsets, making it well suited for high-mix production environments and job shops running frequent changeovers.
