Product Overview
The QCMB2002-CT is a carbide parting and grooving insert with a dedicated chipformer that keeps chips narrow and curls them away from the groove, reducing the risk of jamming in deep parting cuts. Ground periphery accuracy means the insert seats quickly and runs true in standard QCMB-style parting bars. It is well suited to parting-off, necking and face grooving of steel, stainless steel and similar materials on CNC lathes.
