Tungaloy 6774056 Turning Insert CCMT09T308-PSF T9215

Product Description

The TUNGALOY 6774056 is a CCMT09T308-PSF turning insert in manufacturer grade T9215, designed for single-point turning, facing, and boring operations on CNC and manual lathes. The insert is manufactured from solid carbide with a CVD-applied multilayer coating sequence of TiCN, Al2O3, and TiN, delivering thermal stability and wear resistance across a range of workpiece materials. It features an 80-degree diamond shape, a positive rake angle of 20 degrees, a 7-degree relief angle, and a chamfered and honed cutting edge style. With two usable cutting edges and screw-style clamping, it suits production environments where consistent tool life and finish quality are priorities.

This insert is suited for turning, facing, and boring applications in both residential shop and industrial production settings. Primary workpiece materials are steel, stainless steel, and cast iron, corresponding to ISO material codes P, M, and K, with material grades P10 and P20. The PSF chip breaker geometry targets light to medium finishing cuts, as indicated by the maximum depth of cut of 0.0197 inches (0.50 mm). The neutral hand orientation makes it compatible with standard right-hand toolholders configured for CCMT-style inserts.

Key Features

• CVD multilayer coating (TiCN, Al2O3, TiN) for wear resistance and thermal barrier performance
• 80-degree diamond insert shape with positive 20-degree rake for reduced cutting forces
• PSF chip breaker geometry optimized for finishing passes on steel and stainless steel
• Chamfered and honed cutting edge style for edge strength and improved surface finish
• Two cutting edges per insert for extended usable tool life
• Screw-style insert holding for secure, repeatable seating in the toolholder pocket

Compatibility

Designed as an OEM-style replacement or direct-use insert for CCMT09T308-PSF toolholder pockets conforming to ANSI and ISO standards, series CCMT-PSF, industry standard number CCMT 32.52 PSF. Compatible with steel, stainless steel, and cast iron workpieces under ISO P, M, and K classifications.

Installation Notes

Turning inserts are installed and replaced by machinists and toolroom technicians. Power down and lock out the machine spindle before seating or removing inserts. Use the appropriate torx or hex key for the clamp screw and avoid overtightening, which can crack the carbide body. Verify the toolholder pocket and insert seat are clean and free of chips before installation to ensure proper seating and accurate tool geometry.
