Sandvik Coromant 5740645 RCMT22 Carbide Turning Insert

Product Description

The SANDVIK COROMANT 5740645 is a solid carbide turning insert designed for precision metal cutting on CNC lathes and turning centers. Manufactured to the RCMT 06 03 00 H13A ISO designation, this insert features a round (R) shape with a 7-degree relief angle (clearance code C) and tolerance code M. It measures 0.125 inches in thickness and 0.25 inches in inscribed circle diameter. The bright, uncoated H13A carbide grade is suited for applications where a sharp edge and consistent tool life are required. Neutral hand orientation means it can be used in either cutting direction. A licensed machinist or CNC operator handles installation and indexing.

This insert is engineered for turning steel as its primary workpiece material and stainless steel as a secondary workpiece material. It is part of the CoroTurn 107 series, which is commonly deployed in external turning and profiling operations on light to medium cutting depths. The screw-clamping holding method provides rigid insert seating, which is important when maintaining tight tolerances on turned diameters. With four available cutting edges per insert, it delivers multiple usable edges before replacement, which is relevant to tooling cost management in production environments.

Key Features

• Round insert shape (RCMT) with 7-degree relief angle for positive cutting geometry
• H13A uncoated solid carbide grade optimized for steel and stainless steel turning
• Four cutting edges per insert for extended tooling value
• Screw-clamping insert holding method for secure, repeatable seating
• Neutral hand orientation for flexible use in both cutting directions
• Conforms to ISO code RCMT 06 03 00 H13A for cross-reference compatibility

Compatibility

Designed for use in CoroTurn 107 series toolholders that accept RCMT style round inserts with a screw-clamping holding method. Verify toolholder pocket dimensions and ISO insert designation before installation.

Installation Notes

Insert indexing and replacement should be performed by a qualified machinist or CNC tooling technician. Always power down the machine and engage the spindle lock before accessing the turret or tool station. Use the correct Torx or hex key driver specified by the toolholder manufacturer to seat the clamping screw — do not overtighten, as this can fracture the carbide insert. Inspect the insert pocket and clamping screw for debris or wear before seating a new insert.
