Ingersoll Cutting Tools 6213128 Dcmt Turning Insert

Product Description

The INGERSOLL CUTTING TOOLS 6213128 is a DCMT-style indexable carbide turning insert designed for steel machining applications. It carries ANSI code DCMT32.50.5 and ISO code DCMT11T302FM, manufactured to grade TT8115B with a CVD-applied multilayer coating of TiN, TiCN, and Al2O3. The 55-degree diamond (rhombic) insert shape provides a positive rake and positive side clearance for efficient chip formation. With a corner radius of 0.008 inches and a maximum depth of cut of 0.079 inches, this insert is suited for roughing and medium machining passes on steel workpieces. It is held in the toolholder by a screw and offers two usable cutting edges per insert.

This insert targets steel turning operations in general machining environments, covering both roughing and medium machining cycles. The TT8115B grade is characterized by high to moderate wear resistance combined with toughness, making it appropriate for production turning on CNC lathes and manual lathes where consistent tool life on steel is a priority. It is installed and changed by machinists and toolroom technicians. The FM chip breaker geometry promotes controlled chip evacuation across the intended depth-of-cut range.

Key Features

• DCMT insert style with 55-degree diamond shape for reliable nose strength and chip clearance
• CVD multilayer coating: TiN outer layer, TiCN mid layer, Al2O3 inner layer for thermal and wear resistance
• TT8115B carbide grade rated for steel (ISO P) with high to moderate wear resistance and toughness
• FM chip breaker geometry suited for roughing and medium machining operations
• Positive rake and positive side clearance reduce cutting forces on steel
• Screw-clamp holding method provides secure, repeatable insert seating

Compatibility

Designed as an OEM-style indexable turning insert for DCMT-compatible toolholders accepting a 0.375 inch inscribed circle insert with a screw-lock seat and clearance code C.

Installation Notes

This insert is installed by qualified machinists or toolroom technicians on CNC or manual lathes. Shut down the machine and lock out all rotational power before indexing or replacing inserts. Use the appropriate torx or hex key specified by the toolholder manufacturer to secure the clamping screw to the correct feel - do not overtighten, as insert breakage or seat damage may result. Inspect the toolholder pocket and seating surfaces for chips or wear before installing a new insert.
