The CARMEX C18W15MT7 is a solid carbide grooving insert designed for precision external and internal grooving operations on CNC turning centers and lathes. Built to ISO standards, this right-hand insert features a TiAlN coating applied via PVD process, which provides heat resistance and extended tool life when cutting cast iron and similar hard materials. The cutting width measures 0.7 inches with a maximum depth of cut of 0.059 inches, and a corner radius of 0.004 inches for tight, clean groove profiles. Manufactured from submicron-grade solid carbide, this insert offers consistent dimensional accuracy across production runs. Licensed machinists and CNC operators install this part as a direct insert replacement in compatible C18-series toolholders.
The C18W15MT7 is suited for grooving applications in industrial machining environments, including job shops and high-volume production facilities. Its MT7 grade and TiAlN finish make it particularly effective when working with cast iron workpieces classified under ISO material code K. The insert fits C18-series toolholders and is appropriate for both roughing and finishing groove passes within its stated depth-of-cut range. It is sold individually, with a minimum order quantity of three units per order.
Designed for use with C18-series toolholders accepting W15 insert style inserts, per ISO standards. Primary workpiece material is cast iron (ISO material group K). Verify toolholder seat dimensions and insert pocket style before installation.
Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine before seating or replacing any insert. Use the appropriate torx or clamping key to secure the insert to the specified clamp torque indicated by the toolholder manufacturer. Inspect the insert pocket for chips or debris before seating a new insert to prevent premature edge failure.
