Description of Micro 100 FG 250 040 Grooving Projection
Designed for generating square grooves in the face of the part. Polished split face for improved edge retention and chip evacuation while reducing galling. Split geometry makes the tool as rigid as possible. Relief ground along Maximum Bore Depth (L2) to avoid interference during deep hole applications. Sharp corner profile.
Very sharp and high quality carbide. Could not machine more than 12 grooves in hardened 4140 chromoly steel. The tool has very little material under the cutting tip and will break as the material hardens. Highly recommended for aluminum or brass, but stay away from hard or stainless steels.
