Carmex C12W08MT7 Grooving Insert 0.47 in Solid Carbide

Product Description

The CARMEX C12W08MT7 is a solid carbide grooving insert designed for precision grooving and parting operations on CNC lathes and turning centers. Built to the C12 W08 insert style, it features a 0.47-inch cutting width and a TiAlN (titanium aluminum nitride) coating that provides heat resistance and extended tool life in demanding cutting conditions. The MT7 manufacturer grade designation indicates a submicron carbide substrate, delivering the edge toughness and wear resistance required for consistent performance in production environments. This insert is right-hand oriented and suited for machinists and toolroom professionals running tight-tolerance groove profiles.

This insert is intended for use on external grooving applications where a 0.47-inch groove width is required. The maximum depth of cut ranges from 0.000 to 0.075 inches, making it suitable for shallow precision grooves in steel, stainless, and other materials compatible with TiAlN-coated carbide tooling. It is a single-use, non-reversible insert configured for right-hand cutting direction. Typical installation is in a compatible C12 W08 insert holder mounted on a CNC or manual lathe turret.

Key Features

• Solid carbide construction with submicron material grade for superior hardness and edge retention
• TiAlN coating provides thermal barrier and oxidation resistance at elevated cutting temperatures
• 0.47-inch cutting width for consistent, repeatable groove profiles
• Maximum depth of cut up to 0.075 inches for shallow external groove applications
• 0.004-inch corner radius for controlled edge geometry at groove shoulders
• Right-hand cutting orientation for standard lathe setup

Compatibility

Designed for use with C12 W08 style grooving toolholders. Confirm holder compatibility with insert style C12 W08 and right-hand cutting direction before installation.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician familiar with turning insert handling. Power down and lock out the machine before changing inserts. Seat the insert fully in the holder pocket and torque the clamping screw to the toolholder manufacturer specification. Inspect the insert edge for chips or damage before each use, as carbide inserts are brittle and should never be forced into a misaligned pocket.
