Sandvik Coromant has launched CoroCut QI, a range of internal and face-grooving inserts designed for smaller diameters. According to the company, CoroCut QI ensures high process security, reliable grooving operations and precise chip evacuation, resulting in high surface quality grooves.

The addition of CoroCut QI completes the CoroCut Q platform, which already consists of CoroCut QD for parting off and CoroCut QF for secure face grooving. CoroCut QI provides a comprehensive selection of optimized tools for numerous parting and grooving applications, designed specifically for smaller diameters. All inserts fit both internal and face grooving tool holders.

CoroCut QI is divided into internal grooving and face grooving application areas, and is said to be an upgrade of the T-max Q-Cut 151.3 program. The improved design reportedly enables for greater chip control, a 10% productivity increase, 20% improved tool life aided by tighter edge-rounding tolerances and internal coolant for both internal and face grooving tools.

Key features of the CoroCut QI include an optimized tip seat angle for lighter cutting action and cutting forces that aid vibration-free machining, a rail insert seat for a stable and precise insert position ensuring minimal insert movement. In addition, screw-clamped tool holders reportedly ensure stability and high process security, and inserts with high edge line quality increase tool life and surface quality.

Angélica González, product manager of the CoroCut Q platform at Sandvik Coromant, says, “CoroCut QI inserts are specifically designed for small diameters that require great precision. For example, the minimum hole diameter for internal grooving is between 12 and 60 mm with a cutting depth of two and eleven millimeters. Face grooving inserts can be used in a first cut diameter between 16 and 102 mm, with a cutting depth of 5.5 to 20 mm.”

The insert geometries include -GF, a ground sharp insert for internal grooving; -TF, with direct pressed geometry for face grooving and internal grooving and turning; and -RM, ideal for non-linear turning such as internal and face profiling.
