Sandvik Coromant 5724077 Turning Insert Ccgt 3/8 Ic

Product Description

The SANDVIK COROMANT 5724077 is a CCGT-style solid carbide turning insert from the CoroTurn 107 series, designed for precision external and internal turning operations. It carries a dual-layer PVD coating of TiAlN and AlCr2O3, which delivers heat resistance and wear performance when cutting difficult materials. The insert features an 80-degree diamond shape with a neutral hand orientation, a 3/8 inch inscribed circle, a corner radius of 0.0039 inches (0.10 mm), and an insert length of 0.3769 inches. The UM chip breaker geometry controls chip flow efficiently in light to medium cutting passes. Licensed HVAC techs, machinists, and tooling professionals install this insert on CNC lathes and turning centers.

This insert is engineered primarily for stainless steel machining and is rated for secondary use on superalloys and titanium. It fits screw-clamping toolholders that accept CCGT inserts with a 0.1732 inch hole diameter. The CoroTurn 107 series is suited for positive-rake toolholder systems used in finish and semi-finish turning where tight tolerances and surface finish quality are critical. The ISO designation for this insert is CCGT 09 T3 01-UM 1115, which can be used to cross-reference compatible toolholder systems and replacement options.

Key Features

• PVD-coated TiAlN and AlCr2O3 dual-layer finish for heat and wear resistance in stainless steel cutting
• 80-degree diamond insert shape (CCGT) with 7-degree relief angle for positive-rake toolholder compatibility
• UM chip breaker geometry optimized for light to medium depth-of-cut passes
• Screw-clamp insert holding method with 0.1732 inch center hole diameter
• 2 cutting edges per insert for extended tool life per unit
• Neutral hand orientation for flexible mounting on right- or left-hand compatible toolholders

Compatibility

Designed as a replacement-style turning insert for positive-rake CCGT screw-clamp toolholders in the CoroTurn 107 series. ISO code CCGT 09 T3 01-UM 1115 can be used to identify compatible toolholder bodies and adapter systems. Verify toolholder pocket geometry and insert seating before installation.

Installation Notes

Insert replacement should be performed by a qualified machinist or tooling technician with the machine powered down and spindle locked. Use a calibrated torque wrench on the clamping screw to avoid cracking the carbide substrate — consult the toolholder documentation for the recommended fastener specification. Inspect the insert pocket and seating surface for chips or contamination before seating the new insert. Handle carbide inserts with care; edges are brittle and can chip if dropped or struck against hard surfaces.
