Tungaloy 6829228 Ccmt Turning Insert 3/8 in Ic

Product Description

The TUNGALOY 6829228 is a CCMT-style solid carbide turning insert designed for precision metal cutting in CNC and manual lathe applications. It carries a multilayer PVD coating of TiAlN and TiCN under the AH6225 manufacturer grade, delivering thermal resistance and wear life on demanding workpiece materials. The insert features an 80-degree diamond shape with a 3/8-inch inscribed circle, a 0.031-inch corner radius, and a positive rake angle of 10 degrees. A honed cutting edge style reduces micro-chipping at the edge line. Licensed HVAC technicians, machinists, and toolroom professionals install this insert in standard screw-lock toolholders.

This insert is suited for turning, facing, and boring operations on steel and stainless steel workpieces. It falls within ISO material grades P20, P30, M20, and M30, covering a wide range of medium-carbon steels and austenitic stainless grades. The PS chip breaker geometry is optimized for light-to-medium depth-of-cut passes, with a maximum depth of cut of 0.098 inches. It is a neutral-hand insert applicable across right-hand and left-hand toolholders with compatible pocket geometry. The CCMT-PS series is a common production-floor choice for general turning where consistent chip control and surface finish are priorities.

Key Features

• Multilayer PVD TiAlN and TiCN coating under AH6225 grade for extended tool life on steel and stainless steel
• 80-degree diamond insert shape with 2 usable cutting edges per insert
• PS chip breaker geometry supports turning, facing, and boring in a single insert style
• Positive rake angle (10 degrees) reduces cutting forces on light-to-medium passes
• Honed cutting edge reduces edge micro-fracture risk at moderate feed rates
• Screw-lock holding method for secure, repeatable seating in CCMT-compatible toolholders

Compatibility

Designed as an OEM-style replacement and standard production insert for CCMT-compatible screw-lock toolholders conforming to ANSI and ISO CCMT standards (ISO designation CCMT09T308-PS, industry standard CCMT 32.52 PS). Primary workpiece materials are steel (ISO P) and stainless steel (ISO M).

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the machine spindle before seating or replacing the insert. Use the manufacturer-specified torx or hex key for the clamp screw to avoid stripping the screw head - do not overtighten by hand. Inspect the insert pocket and seating surface for chips or debris before installing a new edge.
